About Tana
Tana is an outliner-based knowledge tool that organizes information as nested nodes and adds structured, typed fields on top of them.
Its defining feature is supertags: structured templates with typed fields you can apply to any node in the outline. On top of that, AI commands like extract, summarize, transform, and translate can be run on individual nodes or selections, so the same node holds both structured data and AI actions.
It fits people who want structured, database-like notes rather than plain text, and who work on the web or on the macOS and Windows desktop apps. It is a weaker fit if you rely on mobile, since there is no dedicated mobile app and phone use is limited to the responsive web interface. The supertag and command system also carries a learning curve versus simpler note apps, and it is a closed-source hosted service with no self-hosting, which means vendor lock-in for stored data.
Against simpler note-taking apps, Tana trades ease of entry for a typed, structured outline with built-in AI commands.
