Tana
Build a structured AI-powered second brain for your work
Quick answer
Tana — Build a structured AI-powered second brain for your work. It's freemium. Best for researchers building a connected, queryable knowledge base from papers, notes, and ideas.
Tana is a freemium AI-native workspace that merges notes, tasks, and a dynamic knowledge graph into a single, highly structured environment. Designed for power users, researchers, and teams who want more than a simple note-taking app, Tana uses a concept called supertags to let you define typed, relational structures for any kind of information. Instead of flat documents, every piece of data in Tana becomes a node in a connected graph, meaning your meeting notes, project tasks, contacts, and ideas can all link together intelligently. Built-in AI features handle meeting transcription, voice note capture, and structured data entry, so you spend less time organizing and more time thinking. Whether you are building a personal knowledge base, managing complex research, or coordinating team workflows, Tana adapts to the way your brain works rather than forcing you into rigid templates. The learning curve is steeper than typical note apps, but users who invest the time consistently describe it as a transformative productivity upgrade.
