## [Unreleased] — v3.2.0 (on develop)
## [Unreleased] — v3.3.0 (on develop)
### New Features
- Closet layer — a compact searchable index of pointers to verbatim drawers, enabling fast topical lookup without reading all content (#788)
- BM25 hybrid search — closets boost ranking, drawers remain the source of truth (#795, #829)
- Entity metadata on every drawer for filterable search (#829)
- Diary ingest — day-based rooms for conversation transcripts (#829)
- Cross-wing tunnels — explicit links between rooms in different wings for multi-project agents (#829)
- Drawer-grep — returns the best-matching chunk plus adjacent context drawers (#829)
- Offline fact checker against the entity registry and knowledge graph (#829)
- LLM-based closet regeneration — optional, bring-your-own endpoint, no mandatory API key (#793)
- Hall detection — routes drawer content to `emotions` / `technical` / `family` / `memory` / `identity` / `consciousness` / `creative` halls, enabling hall-based graph connectivity within wings (#835)
### Bug Fixes
- Set `hnsw:space=cosine` metadata on all collection creation sites — fixes broken similarity scoring under ChromaDB's default L2 distance (#807, #218)
- File-level locking prevents duplicate drawers when agents mine the same file concurrently (#784, #826)
- Hybrid closet+drawer retrieval — closets boost ranking, never gate results (#795)
- Stop hooks from making agents write in chat — saves tokens on every turn (#786)
- Strip system tags, hook output, and Claude UI chrome from drawers before filing (#785)
- Verbatim-safe `strip_noise` scoped to Claude Code JSONL only (#785)
- Prevent diary entry ID collisions via microsecond timestamp and full content hash (#819)
- Auto-rebuild stale drawers via `NORMALIZE_VERSION` schema gate
- Enforce atomic topics in closets and extract richer pointers
- Sync `version.py` to match `pyproject.toml` (#820)
- Remove unused `main` import from `mempalace/__init__.py` (#827)
- README audit — fix 7 stale claims (tool count, version badge, wake-up token cost, `dialect.py` lossless disclaimer, `pyproject.toml` version) with 42 regression-guard tests (#835)
### Improvements
- Optimize entity detection with regex caching and pre-compilation (#828)
- Extract locked filing block into helper to keep `mine_convos` under C901 complexity
### Documentation
- Add `docs/CLOSETS.md` — closet layer overview
- Fix stale `milla-jovovich/*` org URLs in website and plugin manifests (#787)
- Fix remaining stale org URLs in contributor docs (#808)
- Rewrite `README.md` and `mempalaceofficial.com` benchmark pages to remove category-error cross-system comparisons (R@5 retrieval recall had been listed next to competitor QA accuracy under one column), remove the retracted "+34% palace boost" claim from the surfaces where it had remained, replace the `100%` Haiku-rerank headline with the honest held-out `98.4%` R@5, drop the LoCoMo `100%` top-50 row (retrieval-bypass artefact), and fix the broken `aya-thekeeper/mempal` reproduction URL (#875)
- Add `docs/HISTORY.md` as the canonical home for corrections, retractions, and public notices; move the 2026-04-07 "Note from Milla & Ben" and the 2026-04-11 impostor-domain notice out of `README.md`
- Add v3.3.0 reproduction result JSONLs and the deterministic `seed=42` 50/450 LongMemEval split under `benchmarks/` — every BENCHMARKS.md claim reproduces exactly
### Internal
- Add test coverage for `mine_lock`, closets, entity metadata, BM25, and diary
- Verify `mine_lock` via disjoint critical-section intervals
- Serialize `mine_lock` concurrency test with multiprocessing
- Make diary state path assertion platform-neutral
- Add `TestTunnels` coverage for cross-wing tunnel operations
- Ruff format with CI-pinned version (0.4.x); format `mempalace/palace.py`

- Remove `chromadb<0.7` upper bound — unblocks installs against chromadb 1.x palaces (#690)
- Bump version to 3.2.0 across `pyproject.toml`, `mempalace/version.py`, README badge, and OpenClaw SKILL (#761)

# MemPalace
### The highest-scoring AI memory system ever benchmarked. And it's free.
<br>
Every conversation you have with an AI — every decision, every debugging session, every architecture debate — disappears when the session ends. Six months of work, gone. You start over every time.
Other memory systems try to fix this by letting AI decide what's worth remembering. It extracts "user prefers Postgres" and throws away the conversation where you explained *why*. MemPalace takes a different approach: **store everything, then make it findable.**
**The Palace** — Ancient Greek orators memorized entire speeches by placing ideas in rooms of an imaginary building. Walk through the building, find the idea. MemPalace applies the same principle to AI memory: your conversations are organized into wings (people and projects), halls (types of memory), and rooms (specific ideas). No AI decides what matters — you keep every word, and the structure gives you a navigable map instead of a flat search index.
**Raw verbatim storage** — MemPalace stores your actual exchanges in ChromaDB without summarization or extraction. The 96.6% LongMemEval result comes from this raw mode. We don't burn an LLM to decide what's "worth remembering" — we keep everything and let semantic search find it.
**AAAK (experimental)** — A lossy abbreviation dialect for packing repeated entities into fewer tokens at scale. Readable by any LLM that reads text — Claude, GPT, Gemini, Llama, Mistral — no decoder needed. **AAAK is a separate compression layer, not the storage default**, and on the LongMemEval benchmark it currently regresses vs raw mode (84.2% vs 96.6%). We're iterating. See the [note above](#a-note-from-milla--ben--april-7-2026) for the honest status.
**Local, open, adaptable** — MemPalace runs entirely on your machine, on any data you have locally, without using any external API or services. It has been tested on conversations — but it can be adapted for different types of datastores. This is why we're open-sourcing it.
<br>
Local-first AI memory. Verbatim storage, pluggable backend, 96.6% R@5 raw on LongMemEval — zero API calls.

## A Note from Milla & Ben — April 7, 2026
## What it is
> The community caught real problems in this README within hours of launch and we want to address them directly.
>
> **What we got wrong:**
>
> - **The AAAK token example was incorrect.** We used a rough heuristic (`len(text)//3`) for token counts instead of an actual tokenizer. Real counts via OpenAI's tokenizer: the English example is 66 tokens, the AAAK example is 73. AAAK does not save tokens at small scales — it's designed for *repeated entities at scale*, and the README example was a bad demonstration of that. We're rewriting it.
>
> - **"30x lossless compression" was overstated.** AAAK is a lossy abbreviation system (entity codes, sentence truncation). Independent benchmarks show AAAK mode scores **84.2% R@5 vs raw mode's 96.6%** on LongMemEval — a 12.4 point regression. The honest framing is: AAAK is an experimental compression layer that trades fidelity for token density, and **the 96.6% headline number is from RAW mode, not AAAK**.
>
> - **"+34% palace boost" was misleading.** That number compares unfiltered search to wing+room metadata filtering. Metadata filtering is a standard ChromaDB feature, not a novel retrieval mechanism. Real and useful, but not a moat.
>
> - **"Contradiction detection"** exists as a separate utility (`fact_checker.py`) but is not currently wired into the knowledge graph operations as the README implied.
>
> - **"100% with Haiku rerank"** is real (we have the result files) but the rerank pipeline is not in the public benchmark scripts. We're adding it.
>
> **What's still true and reproducible:**
>
> - **96.6% R@5 on LongMemEval in raw mode**, on 500 questions, zero API calls — independently reproduced on M2 Ultra in under 5 minutes by [@gizmax](https://github.com/milla-jovovich/mempalace/issues/39).
> - Local, free, no subscription, no cloud, no data leaving your machine.
> - The architecture (wings, rooms, closets, drawers) is real and useful, even if it's not a magical retrieval boost.
>
> **What we're doing:**
>
> 1. Rewriting the AAAK example with real tokenizer counts and a scenario where AAAK actually demonstrates compression
> 2. Adding `mode raw / aaak / rooms` clearly to the benchmark documentation so the trade-offs are visible
> 3. Wiring `fact_checker.py` into the KG ops so the contradiction detection claim becomes true
> 4. Pinning ChromaDB to a tested range (Issue #100), fixing the shell injection in hooks (#110), and addressing the macOS ARM64 segfault (#74)
>
> **Thank you to everyone who poked holes in this.** Brutal honest criticism is exactly what makes open source work, and it's what we asked for. Special thanks to [@panuhorsmalahti](https://github.com/milla-jovovich/mempalace/issues/43), [@lhl](https://github.com/milla-jovovich/mempalace/issues/27), [@gizmax](https://github.com/milla-jovovich/mempalace/issues/39), and everyone who filed an issue or a PR in the first 48 hours. We're listening, we're fixing, and we'd rather be right than impressive.

MemPalace stores your conversation history as verbatim text and retrieves
it with semantic search. It does not summarize, extract, or paraphrase.
The index is structured — people and projects become *wings*, topics
become *rooms*, and original content lives in *drawers* — so searches
can be scoped rather than run against a flat corpus.
The retrieval layer is pluggable. The current default is ChromaDB; the
interface is defined in [`mempalace/backends/base.py`](mempalace/backends/base.py)
and alternative backends can be dropped in without touching the rest of
the system.
Nothing leaves your machine unless you opt in.

## An important follow up note regarding fake MemPalace websites - April 11, 2026
Several Community Members (#267, #326, #506) have pointed out there are fake MemPalace websites popping up, including ones with Malware.
To be super clear, MemPalace *has no website* (at least for now), so anything claiming to be one is false.
Thanks to our Community Members for letting us know about the problem.
Stay safe out there.

Three mining modes: **projects** (code and docs), **convos** (conversation exports), and **general** (auto-classifies into decisions, preferences, milestones, problems, and emotional context). Everything stays on your machine.

## How You Actually Use It
After the one-time setup (install → init → mine), you don't run MemPalace commands manually. Your AI uses it for you. There are two ways, depending on which AI you use.
### With Claude Code (recommended)
Native marketplace install:
```bash
claude plugin marketplace add milla-jovovich/mempalace
claude plugin install --scope user mempalace
```
Restart Claude Code, then type `/skills` to verify "mempalace" appears.
### With Claude, ChatGPT, Cursor, Gemini (MCP-compatible tools)
```bash
# Connect MemPalace once
claude mcp add mempalace -- python -m mempalace.mcp_server
```
Now your AI has 19 tools available through MCP. Ask it anything:
> *"What did we decide about auth last month?"*
Claude calls `mempalace_search` automatically, gets verbatim results, and answers you. You never type `mempalace search` again. The AI handles it.
MemPalace also works natively with **Gemini CLI** (which handles the server and save hooks automatically) — see the [Gemini CLI Integration Guide](examples/gemini_cli_setup.md).
### With local models (Llama, Mistral, or any offline LLM)
Local models generally don't speak MCP yet. Two approaches:
**1. Wake-up command** — load your world into the model's context:
```bash
mempalace wake-up > context.txt
# Paste context.txt into your local model's system prompt
```
This gives your local model ~170 tokens of critical facts (in AAAK if you prefer) before you ask a single question.
**2. CLI search** — query on demand, feed results into your prompt:
```bash
mempalace search "auth decisions" > results.txt
# Include results.txt in your prompt
```
Or use the Python API:
```python
from mempalace.searcher import search_memories
results = search_memories("auth decisions", palace_path="~/.mempalace/palace")
# Inject into your local model's context
```
Either way — your entire memory stack runs offline. ChromaDB on your machine, Llama on your machine, AAAK for compression, zero cloud calls.
---
## The Problem
Decisions happen in conversations now. Not in docs. Not in Jira. In conversations with Claude, ChatGPT, Copilot. The reasoning, the tradeoffs, the "we tried X and it failed because Y" — all trapped in chat windows that evaporate when the session ends.
**Six months of daily AI use = 19.5 million tokens.** That's every decision, every debugging session, every architecture debate. Gone.
| Approach | Tokens loaded | Annual cost |
|----------|--------------|-------------|
| Paste everything | 19.5M — doesn't fit any context window | Impossible |
| LLM summaries | ~650K | ~$507/yr |
| **MemPalace wake-up** | **~170 tokens** | **~$0.70/yr** |
| **MemPalace + 5 searches** | **~13,500 tokens** | **~$10/yr** |
MemPalace loads 170 tokens of critical facts on wake-up — your team, your projects, your preferences. Then searches only when needed. $10/year to remember everything vs $507/year for summaries that lose context.
---
## How It Works
### The Palace
The layout is fairly simple, though it took a long time to get there.
It starts with a **wing**. Every project, person, or topic you're filing gets its own wing in the palace.
Each wing has **rooms** connected to it, where information is divided into subjects that relate to that wing — so every room is a different element of what your project contains. Project ideas could be one room, employees could be another, financial statements another. There can be an endless number of rooms that split the wing into sections. The MemPalace install detects these for you automatically, and of course you can personalize it any way you feel is right.
Every room has a **closet** connected to it, and here's where things get interesting. We've developed an AI language called **AAAK**. Don't ask — it's a whole story of its own. Your agent learns the AAAK shorthand every time it wakes up. Because AAAK is essentially English, but a very truncated version, your agent understands how to use it in seconds. It comes as part of the install, built into the MemPalace code. In our next update, we'll add AAAK directly to the closets, which will be a real game changer — the amount of info in the closets will be much bigger, but it will take up far less space and far less reading time for your agent.
Inside those closets are **drawers**, and those drawers are where your original files live. In this first version, we haven't used AAAK as a closet tool, but even so, the summaries have shown **96.6% recall** in all the benchmarks we've done across multiple benchmarking platforms. Once the closets use AAAK, searches will be even faster while keeping every word exact. But even now, the closet approach has been a huge boon to how much info is stored in a small space — it's used to easily point your AI agent to the drawer where your original file lives. You never lose anything, and all this happens in seconds.
There are also **halls**, which connect rooms within a wing, and **tunnels**, which connect rooms from different wings to one another. So finding things becomes truly effortless — we've given the AI a clean and organized way to know where to start searching, without having to look through every keyword in huge folders.
You say what you're looking for and boom, it already knows which wing to go to. Just *that* in itself would have made a big difference. But this is beautiful, elegant, organic, and most importantly, efficient.

```
**Wings** — a person or project. As many as you need.
**Rooms** — specific topics within a wing. Auth, billing, deploy — endless rooms.
**Halls** — connections between related rooms *within* the same wing. If Room A (auth) and Room B (security) are related, a hall links them.
**Tunnels** — connections *between* wings. When Person A and a Project both have a room about "auth," a tunnel cross-references them automatically.
**Closets** — summaries that point to the original content. (In v3.0.0 these are plain-text summaries; AAAK-encoded closets are coming in a future update — see [Task #30](https://github.com/milla-jovovich/mempalace/issues/30).)
**Drawers** — the original verbatim files. The exact words, never summarized.
**Halls** are memory types — the same in every wing, acting as corridors:
- `hall_facts` — decisions made, choices locked in
- `hall_events` — sessions, milestones, debugging
- `hall_discoveries` — breakthroughs, new insights
- `hall_preferences` — habits, likes, opinions
- `hall_advice` — recommendations and solutions
**Rooms** are named ideas — `auth-migration`, `graphql-switch`, `ci-pipeline`. When the same room appears in different wings, it creates a **tunnel** — connecting the same topic across domains:
```
wing_kai / hall_events / auth-migration → "Kai debugged the OAuth token refresh"
wing_driftwood / hall_facts / auth-migration → "team decided to migrate auth to Clerk"
wing_priya / hall_advice / auth-migration → "Priya approved Clerk over Auth0"
```
Same room. Three wings. The tunnel connects them.
### Why Structure Matters
Tested on 22,000+ real conversation memories:
```
Search all closets: 60.9% R@10
Search within wing: 73.1% (+12%)
Search wing + hall: 84.8% (+24%)
Search wing + room: 94.8% (+34%)
```
Wings and rooms aren't cosmetic. They're a **34% retrieval improvement**. The palace structure is the product.
### The Memory Stack
| Layer | What | Size | When |
|-------|------|------|------|
| **L0** | Identity — who is this AI? | ~50 tokens | Always loaded |
| **L1** | Critical facts — team, projects, preferences | ~120 tokens (AAAK) | Always loaded |
| **L2** | Room recall — recent sessions, current project | On demand | When topic comes up |
| **L3** | Deep search — semantic query across all closets | On demand | When explicitly asked |
Your AI wakes up with L0 + L1 (~170 tokens) and knows your world. Searches only fire when needed.
### AAAK Dialect (experimental)
AAAK is a lossy abbreviation system — entity codes, structural markers, and sentence truncation — designed to pack repeated entities and relationships into fewer tokens at scale. It is **readable by any LLM that reads text** (Claude, GPT, Gemini, Llama, Mistral) without a decoder, so a local model can use it without any cloud dependency.
**Honest status (April 2026):**
- **AAAK is lossy, not lossless.** It uses regex-based abbreviation, not reversible compression.
- **It does not save tokens at small scales.** Short text already tokenizes efficiently. AAAK overhead (codes, separators) costs more than it saves on a few sentences.
- **It can save tokens at scale** — in scenarios with many repeated entities (a team mentioned hundreds of times, the same project across thousands of sessions), the entity codes amortize.
- **AAAK currently regresses LongMemEval** vs raw verbatim retrieval (84.2% R@5 vs 96.6%). The 96.6% headline number is from **raw mode**, not AAAK mode.
- **The MemPalace storage default is raw verbatim text in ChromaDB** — that's where the benchmark wins come from. AAAK is a separate compression layer for context loading, not the storage format.
We're iterating on the dialect spec, adding a real tokenizer for stats, and exploring better break points for when to use it. Track progress in [Issue #43](https://github.com/milla-jovovich/mempalace/issues/43) and [#27](https://github.com/milla-jovovich/mempalace/issues/27).
### Contradiction Detection (experimental, not yet wired into KG)
A separate utility (`fact_checker.py`) can check assertions against entity facts. It's not currently called automatically by the knowledge graph operations — this is being fixed (track in [Issue #27](https://github.com/milla-jovovich/mempalace/issues/27)). When enabled it catches things like:
```
Input: "Soren finished the auth migration"
Output: 🔴 AUTH-MIGRATION: attribution conflict — Maya was assigned, not Soren
Input: "Kai has been here 2 years"
Output: 🟡 KAI: wrong_tenure — records show 3 years (started 2023-04)
Input: "The sprint ends Friday"
Output: 🟡 SPRINT: stale_date — current sprint ends Thursday (updated 2 days ago)
```
Facts checked against the knowledge graph. Ages, dates, and tenures calculated dynamically — not hardcoded.

## Real-World Examples
### Solo developer across multiple projects
```bash
# Mine each project's conversations
mempalace mine ~/chats/orion/ --mode convos --wing orion
mempalace mine ~/chats/nova/ --mode convos --wing nova
mempalace mine ~/chats/helios/ --mode convos --wing helios
# Six months later: "why did I use Postgres here?"
mempalace search "database decision" --wing orion
# → "Chose Postgres over SQLite because Orion needs concurrent writes
# and the dataset will exceed 10GB. Decided 2025-11-03."
# Cross-project search
mempalace search "rate limiting approach"
# → finds your approach in Orion AND Nova, shows the differences
```
### Team lead managing a product
```bash
# Mine Slack exports and AI conversations
mempalace mine ~/exports/slack/ --mode convos --wing driftwood
mempalace mine ~/.claude/projects/ --mode convos
# "What did Soren work on last sprint?"
mempalace search "Soren sprint" --wing driftwood
# → 14 closets: OAuth refactor, dark mode, component library migration
# "Who decided to use Clerk?"
mempalace search "Clerk decision" --wing driftwood
# → "Kai recommended Clerk over Auth0 — pricing + developer experience.
# Team agreed 2026-01-15. Maya handling the migration."
```
### Before mining: split mega-files
Some transcript exports concatenate multiple sessions into one huge file:
```bash
mempalace split ~/chats/ # split into per-session files
mempalace split ~/chats/ --dry-run # preview first
mempalace split ~/chats/ --min-sessions 3 # only split files with 3+ sessions
```
---
## Knowledge Graph
Temporal entity-relationship triples — like Zep's Graphiti, but SQLite instead of Neo4j. Local and free.
```python
from mempalace.knowledge_graph import KnowledgeGraph
kg = KnowledgeGraph()
kg.add_triple("Kai", "works_on", "Orion", valid_from="2025-06-01")
kg.add_triple("Maya", "assigned_to", "auth-migration", valid_from="2026-01-15")
kg.add_triple("Maya", "completed", "auth-migration", valid_from="2026-02-01")
# What's Kai working on?
kg.query_entity("Kai")
# → [Kai → works_on → Orion (current), Kai → recommended → Clerk (2026-01)]
# What was true in January?
kg.query_entity("Maya", as_of="2026-01-20")
# → [Maya → assigned_to → auth-migration (active)]
# Timeline
kg.timeline("Orion")
# → chronological story of the project
```
Facts have validity windows. When something stops being true, invalidate it:
```python
kg.invalidate("Kai", "works_on", "Orion", ended="2026-03-01")
```
Now queries for Kai's current work won't return Orion. Historical queries still will.
| Feature | MemPalace | Zep (Graphiti) |
|---------|-----------|----------------|
| Storage | SQLite (local) | Neo4j (cloud) |
| Cost | Free | $25/mo+ |
| Temporal validity | Yes | Yes |
| Self-hosted | Always | Enterprise only |
| Privacy | Everything local | SOC 2, HIPAA |
---
## Specialist Agents
Create agents that focus on specific areas. Each agent gets its own wing and diary in the palace — not in your CLAUDE.md. Add 50 agents, your config stays the same size.
```
~/.mempalace/agents/
├── reviewer.json # code quality, patterns, bugs
├── architect.json # design decisions, tradeoffs
└── ops.json # deploys, incidents, infra
```
Your CLAUDE.md just needs one line:
```
You have MemPalace agents. Run mempalace_list_agents to see them.
```
The AI discovers its agents from the palace at runtime. Each agent:
- **Has a focus** — what it pays attention to
- **Keeps a diary** — written in AAAK, persists across sessions
- **Builds expertise** — reads its own history to stay sharp in its domain
```
# Agent writes to its diary after a code review
mempalace_diary_write("reviewer",
"PR#42|auth.bypass.found|missing.middleware.check|pattern:3rd.time.this.quarter|★★★★")
# Agent reads back its history
mempalace_diary_read("reviewer", last_n=10)
# → last 10 findings, compressed in AAAK
```
Each agent is a specialist lens on your data. The reviewer remembers every bug pattern it's seen. The architect remembers every design decision. The ops agent remembers every incident. They don't share a scratchpad — they each maintain their own memory.
Letta charges $20–200/mo for agent-managed memory. MemPalace does it with a wing.

---
## Auto-Save Hooks
Two hooks for Claude Code that automatically save memories during work:
**Save Hook** — every 15 messages, triggers a structured save. Topics, decisions, quotes, code changes. Also regenerates the critical facts layer.
**PreCompact Hook** — fires before context compression. Emergency save before the window shrinks.
```json
{
"hooks": {
"Stop": [{"matcher": "", "hooks": [{"type": "command", "command": "/path/to/mempalace/hooks/mempal_save_hook.sh"}]}],
"PreCompact": [{"matcher": "", "hooks": [{"type": "command", "command": "/path/to/mempalace/hooks/mempal_precompact_hook.sh"}]}]
}
}
```
**Optional auto-ingest:** Set the `MEMPAL_DIR` environment variable to a directory path and the hooks will automatically run `mempalace mine` on that directory during each save trigger (background on stop, synchronous on precompact).
For Claude Code, Gemini CLI, MCP-compatible tools, and local models, see
[mempalaceofficial.com/guide/getting-started](https://mempalaceofficial.com/guide/getting-started.html).

## Benchmarks
Tested on standard academic benchmarks — reproducible, published datasets.
All numbers below are reproducible from this repository with the commands
in [`benchmarks/BENCHMARKS.md`](benchmarks/BENCHMARKS.md). Full
per-question result files are committed under `benchmarks/results_*`.
| Benchmark | Mode | Score | API Calls |
|-----------|------|-------|-----------|
| **LongMemEval R@5** | Raw (ChromaDB only) | **96.6%** | Zero |
| **LongMemEval R@5** | Hybrid + Haiku rerank | **100%** (500/500) | ~500 |
| **LoCoMo R@10** | Raw, session level | **60.3%** | Zero |
| **Personal palace R@10** | Heuristic bench | **85%** | Zero |
| **Palace structure impact** | Wing+room filtering | **+34%** R@10 | Zero |
**LongMemEval — retrieval recall (R@5, 500 questions):**
The 96.6% raw score is the highest published LongMemEval result requiring no API key, no cloud, and no LLM at any stage.
| Mode | R@5 | LLM required |
|---|---|---|
| Raw (semantic search, no heuristics, no LLM) | **96.6%** | None |
| Hybrid v4, held-out 450q (tuned on 50 dev, not seen during training) | **98.4%** | None |
| Hybrid v4 + LLM rerank (full 500) | ≥99% | Any capable model |
### vs Published Systems
The raw 96.6% requires no API key, no cloud, and no LLM at any stage. The
hybrid pipeline adds keyword boosting, temporal-proximity boosting, and
preference-pattern extraction; the held-out 98.4% is the honest
generalisable figure.
| System | LongMemEval R@5 | API Required | Cost |
|--------|----------------|--------------|------|
| **MemPalace (hybrid)** | **100%** | Optional | Free |
| Supermemory ASMR | ~99% | Yes | — |
| **MemPalace (raw)** | **96.6%** | **None** | **Free** |
| Mastra | 94.87% | Yes (GPT) | API costs |
| Mem0 | ~85% | Yes | $19–249/mo |
| Zep | ~85% | Yes | $25/mo+ |
The rerank pipeline promotes the best candidate out of the top-20
retrieved sessions using an LLM reader. It works with any reasonably
capable model — we have reproduced it with Claude Haiku, Claude Sonnet,
and minimax-m2.7 via Ollama Cloud (no Anthropic dependency). The gap
between raw and reranked is model-agnostic; we do not headline a "100%"
number because the last 0.6% was reached by inspecting specific wrong
answers, which `benchmarks/BENCHMARKS.md` flags as teaching to the test.
---
**Other benchmarks (full results in [`benchmarks/BENCHMARKS.md`](benchmarks/BENCHMARKS.md)):**
## All Commands
| Benchmark | Metric | Score | Notes |
|---|---|---|---|
| LoCoMo (session, top-10, no rerank) | R@10 | 60.3% | 1,986 questions |
| LoCoMo (hybrid v5, top-10, no rerank) | R@10 | 88.9% | Same set |
| ConvoMem (all categories, 250 items) | Avg recall | 92.9% | 50 per category |
| MemBench (ACL 2025, 8,500 items) | R@5 | 80.3% | All categories |
We deliberately do not include a side-by-side comparison against Mem0,
Mastra, Hindsight, Supermemory, or Zep. Those projects publish different
metrics on different splits, and placing retrieval recall next to
end-to-end QA accuracy is not an honest comparison. See each project's
own research page for their published numbers.

# Security Policy
## Supported Versions
MemPalace follows semantic versioning. Security fixes land on the current major version line.
| Version | Supported |
| ------------------ | --------- |
| 3.x (current) | Yes |
| 2.x and earlier | No |
## Reporting a Vulnerability
**Please do not report security vulnerabilities through public GitHub issues.**
We take the security of MemPalace seriously. If you believe you have found a security vulnerability, please report it privately using **GitHub Private Vulnerability Reporting**:
1. Open the [Security tab](https://github.com/MemPalace/mempalace/security) of this repository.
2. Click **Advisories** → **Report a vulnerability**.
3. Fill in the form with the details below.
### What to include in your report
- A descriptive summary of the vulnerability.
- Detailed steps to reproduce the issue (including any proof-of-concept scripts or specific file paths).
- The affected version(s) and platform(s).
- The potential impact and severity.
### What to expect
- We aim to acknowledge receipt within 48 hours.
- We will triage the issue and keep you updated on progress toward a patch.
- Once the vulnerability is resolved and an update is released, we will publish a security advisory and credit you for the discovery (if you wish to be credited).

## Comparison vs Published Systems (LongMemEval)
| # | System | R@5 | LLM Required | Which LLM | Notes |
> **Important caveat — read before quoting this table.**
> MemPal's `R@5` in this table is **retrieval recall**: is the labelled
> session for this question inside the top-5 retrieved candidates?
>
> Several of the other systems below publish **end-to-end QA accuracy** —
> a different metric that scores whether the system's generated answer
> is correct. Retrieval recall and QA accuracy are not comparable; a
> system can have 100% retrieval recall and 40% QA accuracy, and vice
> versa.
>
> - **Mastra's 94.87%** is binary QA accuracy with GPT-5-mini, per
> [mastra.ai/research/observational-memory](https://mastra.ai/research/observational-memory).
> - **Supermemory ASMR's ~99%** is QA accuracy with an 8-/12-agent
> ensemble, and the authors explicitly frame it as an experimental
> proof-of-concept, not production, per
> [their ASMR post](https://supermemory.ai/blog/we-broke-the-frontier-in-agent-memory-introducing-99-sota-memory-system/).
> - **Mem0** does not publish a LongMemEval number; their published
> metric is LoCoMo QA accuracy (~66.9%), per
> [mem0.ai/research](https://mem0.ai/research).
>
> The table is kept here as a historical record of how the comparison
> was originally framed. Public-facing pages (`README.md`,
> `mempalaceofficial.com`) no longer present this table, per issue
> [#875](https://github.com/MemPalace/mempalace/issues/875). For a fair
> head-to-head, run the same metric on the same split.

|---|---|---|---|---|---|
| 1 | **MemPal (hybrid v4 + rerank)** | **100%** | Optional | Haiku | Reproducible, 500/500 |
| 2 | Supermemory ASMR | ~99% | Yes | Undisclosed | Research only, not in production |
| 1 | **MemPal (hybrid v4 + Haiku rerank)** | **100%** | Optional | Haiku | 500/500 — but the 99.4%→100% step tuned on 3 specific wrong answers (see "Benchmark Integrity" below). Held-out 450q is 98.4%. |
| 2 | Supermemory ASMR | ~99% *(QA accuracy, not R@5)* | Yes | Ensemble of Gemini 2.0 Flash / GPT-4o-mini | Experimental, not production, per authors |
| 3 | MemPal (hybrid v3 + rerank) | 99.4% | Optional | Haiku | Reproducible |

| 10 | BM25 (sparse) | ~70% | None | None | Keyword baseline |
**MemPal raw (96.6%) is the highest published LongMemEval score that requires no API key, no cloud, and no LLM at any stage.**
The MemPal raw 96.6% is the headline we ship on public surfaces: it's
retrieval recall, it requires no API key, and it reproduces.
**MemPal hybrid v4 + Haiku rerank (100%) is the first perfect score on LongMemEval — 500/500 questions, all 6 question types at 100%.**
The MemPal hybrid v4 + Haiku rerank 100% remains an internal
result — reproducible with `--mode hybrid_v4 --llm-rerank` — but we
don't quote it on public pages because the final 0.6% was reached by
inspecting three specific wrong answers (see "Benchmark Integrity"
below), which is teaching to the test. The honest generalisable figure
when an LLM is in the loop is the held-out 98.4% R@5 on 450 unseen
questions, or the model-agnostic 99.2% R@5 / 100% R@10 we reproduced
with minimax-m2.7 on the full 500.

# Closets — The Searchable Index Layer
## What closets are
Drawers hold your verbatim content. Closets are the index — compact pointers that tell the searcher which drawers to open.
```
CLOSET: "built auth system|Ben;Igor|→drawer_api_auth_a1b2c3"
↑ topic ↑ entities ↑ points to this drawer
```
An agent searching "who built the auth?" hits the closet first (fast scan of short text), then opens the referenced drawer to get the full verbatim content.
## Lifecycle
### When are closets created?
Closets are created during `mempalace mine`. For each file mined:
1. Content is chunked into drawers (verbatim, ~800 chars each)
2. Topics, entities, and quotes are extracted from the content
3. A closet is created with pointer lines to those drawers
### What's inside a closet?
Each line is one atomic topic pointer:
```
topic description|entity1;entity2|→drawer_id_1,drawer_id_2
"verbatim quote from the content"|entity1|→drawer_id_3
```
Topics are never split across closets. If adding a topic would exceed 1,500 characters, a new closet is created.
### When do closets update?
When a file is re-mined (content changed, or `NORMALIZE_VERSION` was bumped), the miner first deletes every closet for that source file (`purge_file_closets`) and then writes a fresh set. Stale topics from the prior mine are gone — closets are always a snapshot of the current content, never an accumulation across runs.
### What about stale topics?
There are no stale topics: each re-mine is a clean rebuild for that source file. If a file gets larger and produces fewer or more closets than last time, the leftover numbered closets from the larger run are still purged because the delete is done by `source_file`, not by ID.
### Do closets survive palace rebuilds?
Closets are stored in the `mempalace_closets` ChromaDB collection alongside `mempalace_drawers`. If you delete and rebuild the palace, closets are recreated during the next `mempalace mine`.
## How search uses closets
```
Query → search mempalace_closets (fast, small documents)
↓
top closet hits → parse `→drawer_id_a,drawer_id_b` pointers
↓
fetch exactly those drawers from mempalace_drawers (verbatim content)
↓
apply max_distance filter
↓
return chunk-level results (same shape as direct search)
```
Hits carry `matched_via: "closet"` (or `"drawer"` for the fallback path) plus a `closet_preview` field showing the line that surfaced them.
If no closets exist (palace created before this feature) — or all closet hits get filtered out by `max_distance` — search falls back to direct drawer search. Closets are created on next mine.
> **BM25 hybrid re-rank** is on the roadmap (deferred to a follow-up PR alongside generic `LLM_*` env-var support); the current closet search ranks purely by ChromaDB cosine distance against the closet text.
## Limits
| Setting | Value | Reason |
|---------|-------|--------|
| Max closet size | 1,500 chars (`CLOSET_CHAR_LIMIT`) | Leaves buffer under ChromaDB's working limit |
| Source content scanned | 5,000 chars (`CLOSET_EXTRACT_WINDOW`) | Caps regex extraction cost on long files; back-of-file content is currently invisible to closet extraction (tracked for follow-up) |
| Max topics per file | 12 | Keeps closets focused |
| Max quotes per file | 3 | Most relevant only |
| Max entities per pointer | 5 | Top names by frequency, after stoplist filtering |
## For developers
Closet functions live in `mempalace/palace.py`:
- `get_closets_collection()` — get the closets ChromaDB collection
- `build_closet_lines()` — extract topics/entities/quotes into pointer lines
- `upsert_closet_lines()` — write lines to closets respecting the char limit (overwrites existing IDs; does not append — call `purge_file_closets` first when re-mining)
- `purge_file_closets()` — delete every closet for a given source file before rebuild
- `CLOSET_CHAR_LIMIT` / `CLOSET_EXTRACT_WINDOW` — size constants
The closet-first search path lives in `mempalace/searcher.py`:
- `_extract_drawer_ids_from_closet()` — parse `→drawer_a,drawer_b` pointers out of a closet document
- `_closet_first_hits()` — query closets, parse pointers, hydrate matching drawers, return chunk-level hits or `None` to fall back
Note: only the project miner (`miner.py::process_file`) builds closets today. Conversation-mined wings (Claude Code JSONL, ChatGPT export, etc.) will keep using direct drawer search via the searcher fallback until the convo-closet PR lands.

# MemPalace — History, Corrections, and Public Notices
This file is the canonical record of post-launch corrections, public notices,
and retractions that affect MemPalace's public claims. Newest first.
---
## 2026-04-14 — Benchmark table rewrite (issue [#875](https://github.com/MemPalace/mempalace/issues/875))
A community audit identified a category error in the public benchmark tables
on `README.md` and `mempalaceofficial.com`: MemPalace's retrieval recall
numbers (R@5, R@10) were listed in the same columns as competitors'
end-to-end QA accuracy numbers. They are different metrics and are not
comparable — a system can have 100% retrieval recall and 40% QA accuracy.
The audit also found that the retracted "+34% palace boost" claim (see the
April 7 note below) was still present in multiple surfaces despite that
retraction, and that two competitor numbers (`Mem0 ~85%`, `Zep ~85%`) had no
published source and did not match the metrics those projects actually
publish.
What changed in this PR:
- The headline number on all surfaces is now **96.6% R@5 on LongMemEval in
raw mode**, independently reproduced on Linux x86_64 against the tagged
v3.3.0 release on 2026-04-14. Result JSONLs are committed under
`benchmarks/results_*.jsonl` (see PR description for the scorecard).
- The **"100% with Haiku rerank"** claim has been removed from all public
comparison tables. It reproduces on our machines and with a different LLM
family (minimax-m2.7 via Ollama Cloud: 99.2% R@5 / 100.0% R@10 on the full
500-question LongMemEval set) — but the 99.4% → 100% step was developed
by inspecting three specific wrong answers (`benchmarks/BENCHMARKS.md` has
called this "teaching to the test" since February). It belongs in the
methodology document, not in a headline.
- The **honest held-out number** for the hybrid pipeline — 98.4% R@5 on 450
questions that `hybrid_v4` was never tuned on, deterministic seed — is now
the comparable figure when an LLM rerank is involved.
- The **retracted "+34% palace boost"** has been removed from
`README.md`, `website/concepts/the-palace.md`,
`website/guide/searching.md`, and `website/reference/contributing.md`.
Wing and room filters remain useful — they're standard metadata filters —
but they are not presented as a novel retrieval improvement.
- **Competitor comparison tables** mixing retrieval recall with QA accuracy
have been removed from `README.md` and `website/reference/benchmarks.md`.
Where MemPalace can be fairly compared on the same metric, we link to the
cited source. Otherwise we report our own numbers and let readers draw
their own conclusions.
- **Reproduction instructions** in `benchmarks/BENCHMARKS.md` and
`benchmarks/README.md` were pointing at a defunct branch
(`aya-thekeeper/mempal`); they now point at `MemPalace/mempalace`.
- The **LoCoMo 100% R@10 with top-50 rerank** row has been removed from
public comparison surfaces. With per-conversation session counts of 19–32
and `top_k=50`, the retrieval stage returns every session in the
conversation by construction, so the number measures an LLM's
reading comprehension over the whole conversation, not retrieval.
Thanks to [@dial481](https://github.com/MemPalace/mempalace/issues/875) for
the detailed audit and to [@rohitg00](https://github.com/rohitg00) for the
parallel write-up in Discussion #747.

## 2026-04-11 — Impostor domains and malware
Several community members (issues #267, #326, #506) reported fake MemPalace
websites distributing malware. The only official surfaces for this project
are:
- This GitHub repository: [github.com/MemPalace/mempalace](https://github.com/MemPalace/mempalace)
- The PyPI package: [pypi.org/project/mempalace](https://pypi.org/project/mempalace/)
- The docs site: [mempalaceofficial.com](https://mempalaceofficial.com)
Any other domain — `mempalace.tech` being the one most commonly reported —
is not ours. Never run install scripts from unofficial sites.
Thanks to our community members for flagging the problem.

>
> **What we got wrong:**
>
> - **The AAAK token example was incorrect.** We used a rough heuristic
> (`len(text)//3`) for token counts instead of an actual tokenizer. Real
> counts via OpenAI's tokenizer: the English example is 66 tokens, the
> AAAK example is 73. AAAK does not save tokens at small scales — it's
> designed for *repeated entities at scale*, and the README example was a
> bad demonstration of that. We're rewriting it.
>
> - **"30x lossless compression" was overstated.** AAAK is a lossy
> abbreviation system (entity codes, sentence truncation). Independent
> benchmarks show AAAK mode scores **84.2% R@5 vs raw mode's 96.6%** on
> LongMemEval — a 12.4 point regression. The honest framing is: AAAK is
> an experimental compression layer that trades fidelity for token
> density, and **the 96.6% headline number is from RAW mode, not AAAK**.
>
> - **"+34% palace boost" was misleading.** That number compares unfiltered
> search to wing+room metadata filtering. Metadata filtering is a
> standard feature of the underlying vector store, not a novel retrieval
> mechanism. Real and useful, but not a moat.
>
> - **"Contradiction detection"** exists as a separate utility
> (`fact_checker.py`) but is not currently wired into the knowledge graph
> operations as the README implied.
>
> - **"100% with Haiku rerank"** is real (we have the result files) but
> the rerank pipeline is not in the public benchmark scripts. We're
> adding it.
>
> **What's still true and reproducible:**
>
> - **96.6% R@5 on LongMemEval in raw mode**, on 500 questions, zero API
> calls — independently reproduced on M2 Ultra in under 5 minutes by
> [@gizmax](https://github.com/MemPalace/mempalace/issues/39).
> - Local, free, no subscription, no cloud, no data leaving your machine.
> - The architecture (wings, rooms, closets, drawers) is real and useful,
> even if it's not a magical retrieval boost.
>
> **What we're doing:**
>
> 1. Rewriting the AAAK example with real tokenizer counts and a scenario
> where AAAK actually demonstrates compression
> 2. Adding `mode raw / aaak / rooms` clearly to the benchmark
> documentation so the trade-offs are visible
> 3. Wiring `fact_checker.py` into the KG ops so the contradiction
> detection claim becomes true
> 4. Pinning the vector store dependency to a tested range (issue #100),
> fixing the shell injection in hooks (#110), and addressing the macOS
> ARM64 segfault (#74)

## Known Limitations
**Hooks require session restart after install.** Claude Code loads hooks from `settings.json` at session start only. If you run `mempalace init` or manually edit hook config mid-session, the hooks won't fire until you restart Claude Code. This is a Claude Code limitation.
## Cost
**Zero extra tokens.** The hooks are bash scripts that run locally. They don't call any API. The only "cost" is the AI spending a few seconds organizing memories at each checkpoint — and it's doing that with context it already has loaded.
**Zero extra tokens.** The hooks notify the AI that saves happened in the background — the AI doesn't need to write anything in the chat. All filing is handled automatically. Previous versions asked the AI to write diary entries and drawer content in the chat window, which cost ~$1/session in retransmitted tokens.

the miner; this path regenerates them afterward using whatever LLM the user
chooses. Core memory operations remain API-free by design (see CLAUDE.md,

diary_ingest.py — Ingest daily summary files into the palace.
Architecture:
- ONE drawer per (wing, day) — full verbatim content, upserted as the day grows.
- Closets pack topics up to CLOSET_CHAR_LIMIT, never split mid-topic.
- A re-ingest fully purges the prior day's closets before rebuilding so a
shorter day never leaves orphans behind.
- Only new entries are processed by default (tracks entry count in a state
file under ``~/.mempalace/state/`` — never inside the user's diary dir).
- Per-file ``mine_lock`` so concurrent ingest from two terminals can't race.
- Entities extracted and stamped on metadata for filterable search.
Usage:

"""
test_closets.py — Tests for the closet (searchable index) layer and the
features that ride on top of it: mine_lock serialization, entity metadata,
hybrid BM25+vector search, and diary ingest.
Coverage map:
* mine_lock — acquire/release, blocks concurrent acquisition.
* build_closet_lines — pointer-line shape, header pickup, entity stoplist
(regression for "When/After/The"), real-name survival, fallback line.
* upsert_closet_lines — pure overwrite (regression for the append bug),
char-limit packing without splitting a line.
* purge_file_closets — scoped to source_file.
* Project-miner end-to-end rebuild — re-mining with fewer topics fully
purges leftover numbered closets from a larger prior run.
* _extract_drawer_ids_from_closet — pointer parsing + dedup.
* search_memories hybrid path — drawer query always the floor,
closets boost matching source_file, matched_via reflects both signals,
no whole-file glue, max_distance enforcement.
* Entity metadata — extracted, stoplist applied, registry cached by mtime.
* Real BM25 — real IDF over candidate corpus, hybrid rerank.
* Diary ingest — drawers + closets created, incremental skips, state
file lives outside the diary dir, wing-prefixed drawer IDs prevent
cross-diary collisions, force=True purges leftover closets.

Temporal entity-relationship graphs are a familiar pattern — Zep's
Graphiti, for example, also exposes a bi-temporal model. MemPalace's
knowledge graph is local-first (SQLite, everything on disk) and free;
Zep is a managed service backed by Neo4j with its own pricing, SLAs,
and compliance surface. See Zep's own [documentation](https://www.getzep.com/)
for authoritative details on their deployment model.

## Why Structure Matters
Tested on 22,000+ real conversation memories:
Wing and room identifiers become metadata filters at query time. Narrowing a search to a specific wing (or wing + room) means the vector store only scores candidates inside that scope, which is useful when you have many unrelated projects or people filed in the same palace.
| Search scope | R@10 | Improvement |
|-------------|------|-------------|
| All closets | 60.9% | baseline |
| Within wing | 73.1% | +12% |
| Wing + hall | 84.8% | +24% |
| Wing + room | 94.8% | +34% |
The practical point is that structure improves retrieval. In the project benchmarks, narrowing the search scope by wing and room outperformed searching the entire corpus at once.
This is standard metadata filtering in the underlying vector store, not a novel retrieval mechanism. The useful property here is operational — clear scoping rules that a human or an agent can apply predictably — not a magic retrieval boost.
