Outline editor. The writing surface for clear thinking.
Feels like writing. Works like a knowledge graph. Start simple, end with a system that connects everything you know. Feather-light yet packed with power.
Start writing, structure follows
The outline in Tana Outliner lets you start immediately without setup. Structure emerges naturally. No designing schemas upfront, no choosing between notes and databases.
The outline gives you both freeform writing and structured data at once.
Feels simple. Builds a knowledge graph.
See the big picture while keeping the details
The outline's infinite zoom controls what you see. Zoom in to focus on one item and everything else disappears. Zoom out to see how it all connects.
When you have 200 notes, you can see one or see them all. The details are always there when you need them.
Zoom in to focus. Zoom out for context.
Structure information in a flash
The outline makes shaping information effortless. Move items to explore how ideas relate. Indent to nest, outdent to separate. Create relationships instantly.
Stop duplicating information, start reusing knowledge. Information can grow in multiple places at once. Update it anywhere and it updates everywhere. No rigid folders, no duplicate information to keep in sync.
