Knowledge graph. Write information, not documents.
Tana is a knowledge graph. Just like how a map shows how different cities and towns are connected by roads, a knowledge graph shows how different concepts and entities are connected to each other. This way of connecting information aligns more closely with how the human brain works compared to traditional databases, giving you and your AI a set of capabilities in Tana that are impossible to achieve with other tools.
Tana is one of the few knowledge management tools that moves beyond mimicking static text on paper. It takes the computational medium seriously. It gives regular folks access to a set of powerful primitives that previously only developers could touch.

Old habits die hard, but the document has to go.

The document format has survived from scrolls, via the printing press and typewriter, to various incarnations of live web docs — all without fundamentally changing much. The reason is simple: documents are straight-forward, familiar and it's just what we've always done.Documents are painfully limiting, and invariably lead to scattered and outdated information, time wasted copying and pasting across different tools. They also don't lend themselves well to leveraging the power of AI, because of their lack of proper structure.Why is it that we have to choose between the familiar flexibility of a plain document, and the awkward rigidity of structured tools? At Tana, we believe we have found a sweet spot.

Knowledge graph + outline editor = ❤️

An outline editor is the perfect interface for working with a knowledge graph because it allows for efficient navigation and organization of complex information. However, it has lacked a way to represent structure in your information, beyond a simple hierarchy. Tana has brought two important innovations to the outline editor that solve this issue: supertags and their fields let you capture structured information, and views let you visualise information within the outline editor.
Tana's design reflects deep knowledge of the strengths and weaknesses of existing connected outliner tools.

Knowledge graphs are superior for AI.

As we are entering the AI era, a lot of things will change. The single-purpose software that we've been used to, with their rigid interfaces and traditional databases, will struggle to leverage the new possibilities.Knowledge graphs are better suited for AI than traditional databases because they provide a more versatile and expressive way to represent and connect data.Graph-based data models allows for more complex relationships between your information, which in turn helps AI systems to better understand and reason about it. They can be updated and expanded with ease, making them perfect for ever-changing information and needs.Learn more about AI in Tana
Tana is to the knowledge graph, what Netscape was to the Internet.
