Tana

Tana is an AI-native workspace combining an outliner note editor with a structured knowledge graph powered by "supertags," which turn any bullet into queryable, database-like data. By 2026 it added agentic AI that joins meetings, transcribes in many languages, and generates outputs from graph context. It handles meeting notes, tasks, calendar sync, and collaboration. Best for power users and teams who want a structured, AI-enhanced knowledge environment.

Tana is an AI-native workspace that blends an outliner-style note editor with a structured knowledge graph. Its signature feature is the "supertag": tag any bullet with something like #project, #person, or #meeting and that bullet gains structured fields and can be queried, filtered, and displayed as a database view anywhere in your workspace. This lets unstructured notes double as a flexible database without leaving the writing flow. On top of this, Tana layers AI capabilities. By 2026 it had evolved toward an agentic system where AI agents can participate in meetings, transcribe discussions across dozens of languages, and autonomously generate actionable outputs such as specs, storyboards, and drafts using context from your graph. It also handles meeting notes, tasks, reminders, calendar sync, and collaboration features like mentions and comments. Tana rewards users who invest in setting it up, its power comes from modeling your own information with supertags, which means a steeper learning curve than simpler note apps. It is best for power users, teams, and knowledge workers who want a single, structured, AI-enhanced environment rather than a plain notes tool.
