Overview
Mem is a notes app that bets the useful half of note-taking is retrieval, not capture: semantic search over everything you saved. What earns it a spot in an agentic stack is the MCP server Mem hosts itself, so Claude or ChatGPT can read your saved research while you draft. This is Mem the notes app, not Mem0.
