Tana Outliner
Tana Outliner is Tana's first product. It works like a regular outliner, where you type bullets and indent them, but every bullet is a node in a graph. The same node can appear in many places at once, and stays in sync everywhere.
Supertags are the main idea. When you tag a bullet as a task or a meeting, it picks up fields, and it becomes findable across the whole workspace. There is no schema to design up front. You write, and the structure accumulates as you go.
The same nodes can be viewed as a table, a calendar or a set of cards. We later brought AI into the outline, so you can chat with your notes, and turn voice memos and meetings into structured nodes.
I worked on Tana Outliner from 2021 to mid 2025, on all aspects of the app: conceptual design, product and interaction design, and front end engineering. From mid 2025, I shifted my focus to the new Tana product.
