Mem
AI note app that organizes itself.
About
Mem (mem.ai) is a capture-first note app: you drop notes in via web, mobile, email, or Slack, and its AI auto-tags and auto-links them by embedding similarity. No folders to manage.
Mem 2.0 added an agentic AI layer and Mem Chat for asking questions across your notes. Free tier (25 notes/month); Pro around $12-15/month. Great at surfacing past notes, weaker at turning them into finished documents.
What it can do
- Frictionless capture (web, mobile, email, Slack)
- Auto-tagging and auto-linking
- Mem Chat (Q&A over your notes)
- AI-powered deep search
- Collections

Setup
- Sign up at mem.ai (free tier available).
