Tana

What it does

Tana turns hierarchical notes into structured data — supertags make any node a database row with fields and views. Research, CRM notes and project tracking live in one graph with AI commands over the lot.

The learning curve is real; the payoff is a personal operating system. Free tier; paid plans for AI credits and teams.
