+ + Memory is + identity. +
++ An AI that forgets cannot know you. MemPalace keeps every word you have + shared — verbatim, on your machine, forever available. One hundred + percent recall by design. +

+ ii anatomy of a palace
+
+
+
+
+
+ the method of loci, updated
+
+ + Wings. Rooms. Drawers. +
++ A two-thousand-year-old memory technique, reworked for a machine. + Broad categories nest time-based groupings; time-based groupings hold + verbatim drawers. A symbolic index lets the model scan thousands of + drawers in a single breath and open only the ones it needs. +
+
+
+ W — wing
+
+
+
+ R — room
+
+
+
+ D — drawer
+
+
+ The Wing
+people · projects · topics
+A broad region of the palace, keyed to a real entity — a person by name, a project by codename, a domain of your life. Entity-first, always.
+
+
+
+ The Room
+days · sessions · threads
+Inside a wing sit rooms — discrete units of time. One room per day, or one per session. Walk the corridor and the palace unfolds chronologically, room by room.
+
+
+
+ The Drawer
+verbatim · permanent · exact
+Each room holds drawers. A drawer is a single chunk of verbatim content — the exact words, untouched. The palace's promise is kept here.
+
+
+
+ iii the aaak dialect
+
+
+ index ← verbatim
+
+
+ + A compressed symbolic language for finding, not remembering. +
++ The content stays verbatim — always. The index above it is written + in AAAK: a dense symbolic dialect an LLM can scan at a glance. Tens of + thousands of entries, one pass, exact drawer located. +

++ "My son's name is Noah. He turns six + on September 12th. He loves dinosaurs — + especially the therizinosaurus because of the + claws. We want to do a small party at the park on Glebe + Point Road, maybe eight kids." +
++ — kept as spoken. never rewritten. +
+The pointer, as indexed.

+ Ninety-plus percent compression on the pointer layer. One hundred percent + fidelity on the content layer. You get speed without ever losing a word. +

+ Local-first
+ChromaDB on disk. SQLite for the knowledge graph. Nothing is uploaded. Nothing is synced. Your palace lives under a single directory on your machine.
+path · ~/.mempalace
+ Zero API
+Extraction, chunking, and embedding all run locally. No OpenAI key, no Anthropic key, no sentence-transformers endpoint. The memory works even offline, on a plane.
+keys required · none
+ Background hooks
+Filing and indexing happen silently through Claude Code hooks. On session end, on pre-compaction. You write. The palace fills itself behind the curtain.
+hook budget · <500 ms
+ Temporal graph
+Relationships across entities with valid-from and valid-to dates. Who worked on what. When did this change. Facts that were true then, and may not be now.
