What is Tana AI?
Tana AI is a knowledge management and productivity tool developed by Tana that enables professionals and teams to streamline knowledge management, note-taking, and task management. It combines an outliner with advanced AI capabilities to create a connected knowledge graph. Functioning as an all-in-one workspace, Tana AI allows users to organize notes, tasks, and projects within a dynamic knowledge graph, emphasizing a 'write first, tag later' philosophy where the tool builds structure around content. Key developments include a $25 million Series A funding round in February 2025 and the evolution into two distinct products as of March 2026: 'Tana Outliner' and a 'new Tana' for collaboration and agentic work.
