Capture rough, retrieve smart.

Most PKM systems fail because the capture/organise overhead outweighs the retrieval benefit. AI tilts the balance.

The PKM problem

If you spend more time tagging notes than reading them, you've built a museum, not a brain.

The system

  • Capture freely in one place (Mem, Notion AI, or Apple Notes).
  • Skip tagging — let AI search do the work.
  • Weekly: ask AI for highlights and emerging themes.
  • Monthly: write one synthesis essay from the highlights.

Key takeaways

  • Capture > organise.
  • Let AI replace your tagging system.
  • Synthesise monthly to compound learning.
