Mem AI

Mem is an AI-powered note-taking app that automatically organizes and connects your notes, with Mem Chat to ask questions about your own notes and get answers with cited sources. Version 2.0 (2026) significantly improved speed and stability.

Taking notes that organize and relate themselves automatically through AI, so you can ask your notes directly instead of searching for them manually.

For knowledge workers who accumulate lots of scattered notes and want AI to organize them and make them searchable, rather than for team work (collaboration is limited).
