Mem is an AI note-taking and personal knowledge management app that captures notes and automatically organizes and links them, aiming to reduce the manual filing and tagging typical of traditional note apps. Version Mem 2.0, released in 2026, added faster performance and deeper AI features described as a 'thought partner' for surfacing relevant past notes during writing or planning. The app is available as native apps for Mac, Windows and iOS as well as a web app, with offline editing that syncs once back online. A free tier covers core note-taking with capped monthly AI usage, while a paid Pro tier raises those limits, and a Teams plan adds shared workspaces for collaboration.
Notion is a single space where you can think, write, and plan. Capture thoughts, manage projects, or even run an entire company.
Free for individuals; paid plans start at $10/user/month for teams.
