Overview
anathem gives coding agents such as Claude Code and opencode a memory that lasts between sessions. It is one binary and one SQLite file on your machine, with no background service, no server and no API key, and it registers itself as an MCP server. The agent saves what it learned only when asked, with no model call when writing, and searches it later with keyword search; an optional 22.5 MB pack adds vector search that helps across languages. Corrections replace old notes while keeping them in history. The binaries are unsigned, so your operating system may warn about them; each release has checksums and a signature you can verify. You get a searchable local memory your agent can save to and recall from.
