AI memory

agent-memory

Gives AI agents a lasting memory stored as plain text files you can read, search and keep.

What it does

AI agents usually forget everything when a session ends. agent-memory saves what they learn as plain Markdown files (simple text files) in one folder on your computer. Claude Code, Codex CLI, Muse Code and other tools that can run commands can all share that same folder.

When an agent needs to remember something, the tool searches the files locally and returns a ranked list of matching files. The agent then opens only as much of each file as it needs. New memories are written automatically at the end of conversations, and a separate 'sleep-time' pass tidies and combines memories later. Deletions only happen after you confirm them.

The search index is just a shortcut that can be deleted and rebuilt without losing anything, because the text files are the real record. Its makers say no API key is needed, because it borrows reasoning from the agent tool you already use.

Who it's for

People who use command-line AI coding agents like Claude Code or Codex and want them to remember past work between sessions.

Can I use it without coding?
