Overview

MemPalace stores your conversation history and project files on your own computer as the original text and lets your AI assistant search it by meaning. Content is organised into wings for people and projects, rooms for topics and drawers for the saved text, and an MCP server gives the assistant tools to read and write it. A knowledge graph and per-agent diaries sit on top. It suits people who run long projects with a coding assistant and want it to remember earlier decisions.

It keeps your words exactly as written instead of summaries, and says nothing leaves your machine unless you opt in.

Try these first

Start with the first one: it is a small task you can check easily.

Good to know

You work on a project with an AI assistant for weeks and each new chat starts blank. MemPalace saves past conversations and project files, then lets the assistant search them and answer with the original wording.

Limits

  • Claude Code sessions expire after 30 days unless the auto-save hooks are set up; older sessions can be mined in with the mine command.
  • The first command that needs embeddings downloads the embedding model and needs network access.
