The honest brief

Heptabase

Pairs an infinite visual whiteboard with AI that answers across your own PDFs, videos, and notes — spatial sense-making most PKM apps lack.

  • Spatial whiteboards for connecting ideas
  • AI Q&A cited across your own sources
  • True cross-platform with offline support
  • Strong PDF annotation and web clipping
  • No free tier — paid plans only
  • AI usage capped by monthly credits
  • Visual-first approach has a learning curve

Mem

Strongest auto-organization of any AI notes app — you never file anything; AI links and resurfaces it for you.

  • No manual filing or folders
  • Natural-language search that works
  • Auto-links related notes
  • Fast capture-to-retrieval
  • No free plan; $15/mo
  • AI useful only after ~20-50 notes
  • Limited offline access and export
  • Weaker for structured/team work
