description	Local-first AI memory system — 96.6% R@5 trên LongMemEval, verbatim storage (không lossy summary), MCP server 29 tools, ChromaDB/Qdrant/pgvector backends. Zero API calls.

MemPalace: hệ thống bộ nhớ AI local-first, benchmark cao nhất open-source — lưu verbatim (không tóm tắt), retrieval theo không gian (wing/room/drawer).

Install

uv tool install mempalace
# hoặc
pipx install mempalace

Cách dùng

# Index project hoặc Claude Code conversation archives
mempalace mine ./project/

# Semantic search
mempalace search "database migration strategy"

# Load context cho session mới
mempalace wake-up

Architecture

Palace structure:
  Wing  — người, project (top-level namespace)
  Room  — topic trong wing
  Drawer — content gốc verbatim

Backends:
  ChromaDB  (default, local)
  SQLite    (exact match, correctness verification)
  Qdrant    (REST external)
  pgvector  (PostgreSQL)

MCP Server

{
  "mcpServers": {
    "mempalace": {
      "command": "mempalace",
      "args": ["mcp"]
    }
  }
}

29 tools: palace operations, cross-wing navigation, agent diaries, search.

Performance

96.6% R@5 on LongMemEval  — zero API calls (embedding only)
98.4% R@5                 — hybrid pipeline (keyword + temporal boost)
>99%                      — với LLM reranking (Claude/Ollama compatible)

Tính năng nổi bật

• Verbatim storage — không lossy extraction, không paraphrase
• Knowledge graph — temporal entity-relationship với validity windows
• Auto-save hooks — periodic save + pre-compression backup cho Claude Code
• Agent diaries — per-agent wings riêng, runtime discovery
• Privacy — không có gì rời máy trừ khi opt-in

So với Memory OS
