About Tana

Tana is a structured note-taking and knowledge management application designed around the concept of an AI-native workspace. At its core, the tool organizes information using a node-based outline system where every piece of content is a typed, tagged object. Its signature feature, called supertags, allows users to define structured templates that automatically apply fields, commands, and behaviors to any node that receives that tag. This means a note tagged as a "meeting" can instantly inherit fields for attendees, action items, and follow-up dates, turning freeform notes into queryable, structured data. The tool supports daily agenda views that pull tagged nodes into a unified planner, giving users a single place to track tasks, meetings, and priorities across their workspace. Voice memo capture is also built in, allowing users to record and transcribe thoughts on the go, which then land in the inbox for later processing and tagging. AI features are woven throughout the product rather than bolted on as an afterthought — users can invoke AI commands directly within nodes to summarize content, generate drafts, extract action items, or transform raw notes into structured entries. This makes Tana particularly well suited for knowledge workers, researchers, writers, and anyone who deals with high volumes of loosely connected information and needs to impose structure without abandoning flexibility. Tana is positioned for power users who are comfortable investing time in setting up a personal system. It rewards those willing to define their own supertag schemas and workflows, but carries a steeper learning curve than simpler note-taking apps. The product has been available through an invite-based access model and offers a free tier for individual use, with paid plans aimed at teams and users who need collaboration features or higher usage limits. It runs as a web application with companion mobile apps for capture.
