Local-first AI memory system for Claude that stores conversation history verbatim — no summarizing or paraphrasing — and retrieves it with semantic search. The index is organized as a memory palace: people and projects become wings, topics become rooms, and original content lives in drawers, so searches can be scoped instead of run against a flat corpus. Retrieval backend is pluggable (ChromaDB by default) and nothing leaves your machine unless you opt in.
- Store and retrieve project context across multiple sessions
- Search past conversations and decisions using natural language
- Organize persistent memory in a structured hierarchy
Solves context loss between Claude sessions with verbatim, locally stored memory and scoped semantic search — the palace structure lets retrieval target a person, project, or topic instead of a flat corpus, and no data leaves your machine unless you opt in.
Teams running long-lived Claude projects who want local-first context persistence across sessions and are comfortable adopting a fast-moving young project after their own security review.

Things to check
- Watch for impostor sites: the only official sources are the MemPalace/mempalace GitHub repo, the mempalace PyPI package, and mempalaceofficial.com — the project warns other domains may distribute malware. Claude Code sessions expire in 30 days unless auto-save hooks are wired (see project docs). Retrieval quality claims (96.6% R@5 on LongMemEval) come from the project itself; verify against your own workload before production use.
