Tana

Tana is an "AI-native" workspace that has won over a community of advanced productivity enthusiasts. Its core idea: supertags, which turn any note into structured, reusable, queryable data, without leaving free-form writing behind.

What is Tana used for?

You take notes like in an ideation tool, then apply supertags (a task, a person, a meeting) that instantly generate fields, views, and relationships. Notes become a living database: you filter, aggregate, and build dashboards from the same content. AI sits at the core of the tool, with per-plan credits for writing, summarizing, and enriching nodes. Tana appeals to those who want the power of a structured database with the fluidity of a text editor.

Tana or Notion and Capacities?

Compared to Notion, more visual and mainstream, Tana targets advanced users who want to structure from the bottom up, on the fly. Compared to Capacities, another knowledge tool, it pushes AI and the supertag logic further. In exchange, its learning curve is real, and the tool isn't built for simple mainstream use.

What are Tana's limitations?

That power comes with a learning cost: supertags and the database logic require an investment. AI credits are capped per plan, and the tool, still young, remains built for power users more than teams looking for simplicity.
