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
