Memento

One memory layer for every AI assistant you use.

A local-first, LLM-agnostic memory layer for AI assistants. Memento runs an MCP server over a single SQLite file on your machine, so any MCP-capable AI assistant — Claude Desktop, Claude Code, Cursor, GitHub Copilot, Cline, OpenCode, Aider, custom agents — can read and write durable, structured memory about you, your work, and your decisions.
