What It Does
MemPalace stores AI conversation history as verbatim text — no AI-generated summaries, no paraphrasing — then retrieves it with semantic search scoped to a structured hierarchy: "wings" projects/people, "rooms" topics, and "drawers" raw content. Nothing leaves your machine by default. A 29-tool MCP server makes it available to Claude Code, Cursor, and any other MCP-compatible agent without extra configuration.
Why It's Blowing Up
MemPalace launched on April 5, 2026, and hit 22,000 stars in 48 hours on the strength of a single credible number: 96.6% R@5 on LongMemEval — raw retrieval, no LLM, no API key at any stage. That score sits above every paid competitor in the category and landed the repo at the top of Hacker News.
The timing hit a genuine pain point. Claude Code, Cursor, and Gemini CLI all gained long-running agent capabilities this year, and losing context between sessions became a daily friction point for developers. MemPalace's approach — mine your conversations once, recall them forever from a local corpus — filled that gap without requiring any subscription or cloud account.
Today's v3.3.4 release deepens the local-only story: mempalace init now detects a running Ollama, LM Studio, or llama.cpp instance and uses it for free zero-cloud setup, falling back gracefully if none is found. A new cross-wing tunnel feature also connects related topics across separate projects, so agents find relevant context without knowing which project wing to search.
