About Tana

Tana is a commercial knowledge workspace built on an outliner, where every note is a node in a nested list. Its signature concept is supertags, which turn nodes into structured, typed items with their own fields, letting notes, tasks and projects live in the same system.

The product also includes AI features for working with the content a user has captured. Tana is a cloud-based app rather than a self-hosted product, and it is relevant to people who want a flexible, database-like note system; check the official site for current capabilities and pricing.
