What is Tana AI?
AI-Augmented Outliner That Thinks Like You Do
Tana is a powerful AI-augmented outliner and knowledge base tool that combines a flexible outline structure with AI capabilities to help users capture, organize, and develop knowledge. It introduces the concept of "supertags" — typed nodes that give structure to information — combined with AI commands that can process, search, and generate content across your entire knowledge graph.
A Programmable Thinking Environment
Tana's distinctive approach is treating everything as a structured node that can be typed, queried, and processed by AI. Users can build custom workflows where AI agents process nodes — summarizing content, extracting data, generating new nodes, and even interacting with external services. This programmability makes Tana especially appealing to power users who want their note-taking tool to be a genuine personal knowledge operating system.
- Supertags for structured knowledge organization
- AI commands that operate on any node or selection
- Search and query across your entire knowledge base
- Custom AI workflows and agent automation
