And it's free. [Permalink: The highest-scoring AI memory system ever benchmarked. And it's free.](https://github.com/milla-jovovich/mempalace#the-highest-scoring-ai-memory-system-ever-benchmarked-and-its-free) 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 makes it searchable. That structure alone improves retrieval by 34%. **AAAK** — A lossless shorthand dialect designed for AI agents. Not meant to be read by humans — meant to be read by your AI, fast. 30x compression, zero information loss. Your AI loads months of context in ~120 tokens. And because AAAK is just structured text with a universal grammar, it works with **any model that reads text** — Claude, GPT, Gemini, Llama, Mistral. No decoder, no fine-tuning, no cloud API required. Run it against a local model and your entire memory stack stays offline. Nothing else like it exists. **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.

No cloud. Local only. | Reproducible — runners in [benchmarks/](https://github.com/milla-jovovich/mempalace/blob/main/benchmarks). [Full results](https://github.com/milla-jovovich/mempalace/blob/main/benchmarks/BENCHMARKS.md). * * * ## Quick Start [Permalink: Quick Start](https://github.com/milla-jovovich/mempalace#quick-start) ``` pip install mempalace # Set up your world — who you work with, what your projects are mempalace init ~/projects/myapp # Mine your data mempalace mine ~/projects/myapp # projects — code, docs, notes mempalace mine ~/chats/ --mode convos # convos — Claude, ChatGPT, Slack exports mempalace mine ~/chats/ --mode convos --extract general # general — classifies into decisions, milestones, problems # Search anything you've ever discussed mempalace search "why did we switch to GraphQL" # Your AI remembers mempalace status ``` 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 [Permalink: How You Actually Use It](https://github.com/milla-jovovich/mempalace#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, ChatGPT, Cursor (MCP-compatible tools) [Permalink: With Claude, ChatGPT, Cursor (MCP-compatible tools)](https://github.com/milla-jovovich/mempalace#with-claude-chatgpt-cursor-mcp-compatible-tools) ``` # 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. ### With local models (Llama, Mistral, or any offline LLM) [Permalink: With local models (Llama, Mistral, or any offline LLM)](https://github.com/milla-jovovich/mempalace#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: ``` 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: ``` mempalace search "auth decisions" > results.txt # Include results.txt in your prompt ``` Or use the Python API: ``` 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 [Permalink: The Problem](https://github.com/milla-jovovich/mempalace#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 [Permalink: How It Works](https://github.com/milla-jovovich/mempalace#how-it-works) ### The Palace [Permalink: The Palace](https://github.com/milla-jovovich/mempalace#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. ``` ┌─────────────────────────────────────────────────────────────┐ │ WING: Person │ │ │ │ ┌──────────┐ ──hall── ┌──────────┐ │ │ │ Room A │ │ Room B │ │ │ └────┬─────┘ └──────────┘ │ │ │ │ │ ▼ │ │ ┌──────────┐ ┌──────────┐ │ │ │ Closet │ ───▶ │ Drawer │ │ │ └──────────┘ └──────────┘ │ └─────────┼──────────────────────────────────────────────────┘ │ tunnel │ ┌─────────┼──────────────────────────────────────────────────┐ │ WING: Project │ │ │ │ │ ┌────┴─────┐ ──hall── ┌──────────┐ │ │ │ Room A │ │ Room C │ │ │ └────┬─────┘ └──────────┘ │ │ │ │ │ ▼ │ │ ┌──────────┐ ┌──────────┐ │ │ │ Closet │ ───▶ │ Drawer │ │ │ └──────────┘ └──────────┘ │ └─────────────────────────────────────────────────────────────┘ ``` **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** — compressed summaries that point to the original content. Fast for AI to read. **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 [Permalink: Why Structure Matters](https://github.com/milla-jovovich/mempalace#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 [Permalink: The Memory Stack](https://github.com/milla-jovovich/mempalace#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 Compression [Permalink: AAAK Compression](https://github.com/milla-jovovich/mempalace#aaak-compression) AAAK is a lossless dialect — 30x compression, readable by any LLM without a decoder. It works with **Claude, GPT, Gemini, Llama, Mistral** — any model that reads text. Run it against a local Llama model and your whole memory stack stays offline. **English (~1000 tokens):** ``` Priya manages the Driftwood team: Kai (backend, 3 years), Soren (frontend), Maya (infrastructure), and Leo (junior, started last month). They're building a SaaS analytics platform. Current sprint: auth migration to Clerk. Kai recommended Clerk over Auth0 based on pricing and DX. ``` **AAAK (~120 tokens):** ``` TEAM: PRI(lead) | KAI(backend,3yr) SOR(frontend) MAY(infra) LEO(junior,new) PROJ: DRIFTWOOD(saas.analytics) | SPRINT: auth.migration→clerk DECISION: KAI.rec:clerk>auth0(pricing+dx) | ★★★★ ``` Same information. 8x fewer tokens. Your AI learns AAAK automatically from the MCP server — no manual setup. ### Contradiction Detection [Permalink: Contradiction Detection](https://github.com/milla-jovovich/mempalace#contradiction-detection) MemPalace catches mistakes before they reach you: ``` 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 [Permalink: Real-World Examples](https://github.com/milla-jovovich/mempalace#real-world-examples) ### Solo developer across multiple projects [Permalink: Solo developer across multiple projects](https://github.com/milla-jovovich/mempalace#solo-developer-across-multiple-projects) ``` # 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.

Maya handling the migration." ``` ### Before mining: split mega-files [Permalink: Before mining: split mega-files](https://github.com/milla-jovovich/mempalace#before-mining-split-mega-files) Some transcript exports concatenate multiple sessions into one huge file: ``` 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 [Permalink: Knowledge Graph](https://github.com/milla-jovovich/mempalace#knowledge-graph) Temporal entity-relationship triples — like Zep's Graphiti, but SQLite instead of Neo4j. Local and free. ``` 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: ``` 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 [Permalink: Specialist Agents](https://github.com/milla-jovovich/mempalace#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. * * * ## MCP Server [Permalink: MCP Server](https://github.com/milla-jovovich/mempalace#mcp-server) ``` claude mcp add mempalace -- python -m mempalace.mcp_server ``` ### 19 Tools [Permalink: 19 Tools](https://github.com/milla-jovovich/mempalace#19-tools) **Palace (read)** | Tool | What | | --- | --- | | `mempalace_status` | Palace overview + AAAK spec + memory protocol | | `mempalace_list_wings` | Wings with counts | | `mempalace_list_rooms` | Rooms within a wing | | `mempalace_get_taxonomy` | Full wing → room → count tree | | `mempalace_search` | Semantic search with wing/room filters | | `mempalace_check_duplicate` | Check before filing | | `mempalace_get_aaak_spec` | AAAK dialect reference | **Palace (write)** | Tool | What | | --- | --- | | `mempalace_add_drawer` | File verbatim content | | `mempalace_delete_drawer` | Remove by ID | **Knowledge Graph** | Tool | What | | --- | --- | | `mempalace_kg_query` | Entity relationships with time filtering | | `mempalace_kg_add` | Add facts | | `mempalace_kg_invalidate` | Mark facts as ended | | `mempalace_kg_timeline` | Chronological entity story | | `mempalace_kg_stats` | Graph overview | **Navigation** | Tool | What | | --- | --- | | `mempalace_traverse` | Walk the graph from a room across wings | | `mempalace_find_tunnels` | Find rooms bridging two wings | | `mempalace_graph_stats` | Graph connectivity overview | **Agent Diary** | Tool | What | | --- | --- | | `mempalace_diary_write` | Write AAAK diary entry | | `mempalace_diary_read` | Read recent diary entries | The AI learns AAAK and the memory protocol automatically from the `mempalace_status` response. No manual configuration. * * * ## Auto-Save Hooks [Permalink: Auto-Save Hooks](https://github.com/milla-jovovich/mempalace#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. ``` { "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"}]}] } } ``` * * * ## Benchmarks [Permalink: Benchmarks](https://github.com/milla-jovovich/mempalace#benchmarks) Tested on standard academic benchmarks — reproducible, published datasets. | 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 | The 96.6% raw score is the highest published LongMemEval result requiring no API key, no cloud, and no LLM at any stage. ### vs Published Systems [Permalink: vs Published Systems](https://github.com/milla-jovovich/mempalace#vs-published-systems) | 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+ | * * * ## All Commands [Permalink: All Commands](https://github.com/milla-jovovich/mempalace#all-commands) ``` # Setup mempalace init # guided onboarding + AAAK bootstrap # Mining mempalace mine # mine project files mempalace mine --mode convos # mine conversation exports mempalace mine --mode convos --wing myapp # tag with a wing name # Splitting mempalace split # split concatenated transcripts mempalace split --dry-run # preview # Search mempalace search "query" # search everything mempalace search "query" --wing myapp # within a wing mempalace search "query" --room auth-migration # within a room # Memory stack mempalace wake-up # load L0 + L1 context mempalace wake-up --wing driftwood # project-specific # Compression mempalace compress --wing myapp # AAAK compress # Status mempalace status # palace overview ``` All commands accept `--palace ` to override the default location. * * * ## Configuration [Permalink: Configuration](https://github.com/milla-jovovich/mempalace#configuration) ### Global (`~/.mempalace/config.json`) [Permalink: Global (~/.mempalace/config.json)](https://github.com/milla-jovovich/mempalace#global-mempalaceconfigjson) ``` { "palace_path": "/custom/path/to/palace", "collection_name": "mempalace_drawers", "people_map": {"Kai": "KAI", "Priya": "PRI"} } ``` ### Wing config (`~/.mempalace/wing_config.json`) [Permalink: Wing config (~/.mempalace/wing_config.json)](https://github.com/milla-jovovich/mempalace#wing-config-mempalacewing_configjson) Generated by `mempalace init`.
