Mem (mem.ai)

Mem is an AI-native notes app built around the idea that organisation should be the computer's job, not yours. Instead of forcing you to choose a folder, project or tag for every note, Mem connects new entries to related ones automatically, then surfaces them when relevant via a chat interface that reads across your entire workspace. You can paste meeting transcripts, voice memos, articles, PDFs and screenshots, and Mem will summarise them, extract tasks, and link them to the people, companies and projects already mentioned in your knowledge base. The Mem chat is particularly strong for 'what did I say about X last quarter' or 'pull every decision we made on launch dates,' because the index spans your full history rather than just the active document. Teams get shared spaces with permissioned access, a Slack integration that captures messages into searchable memory, and a smart write feature that drafts in the user's voice. Mem has positioned itself in 2026 as the bridge between personal AI memory (think of it as a second brain) and team knowledge tools like Notion or Confluence, and is increasingly used as a working layer between AI assistants and human-written context.
