Claude Code keeps your chat history on your computer for 30 days by default, then clears out old sessions. So the reasons behind your decisions, the fixes that worked and the plans you made quietly disappear. This free, open-source memory, past 60,000 GitHub stars, saves every chat word for word and files it by person, project and topic. Months later you ask Claude a plain question and it pulls up the exact conversation.
Here's what it does, how to set it up in about ten minutes, and what to watch out for.
What it does for you
- Saves your chats word for word. It doesn't summarize or rewrite them, so nothing gets lost in translation.
- Files them like a palace: a wing per person or project, a room per topic, the original text in drawers.
- Lets Claude search your past chats by meaning ("why did we rewrite the landing page?") and quote the answer.
- Saves on its own while you work and right before Claude shortens a long chat.
- Runs on your computer with no API key. Nothing leaves your machine unless you turn that on.
