About Tana

Tana is a powerful 'knowledge graph' and task manager that uses a unique tagging system called 'Supertags'. By tagging a node, you instantly give it a set of fields and behaviors, turning a simple list of notes into a structured database without the overhead of traditional tables.

Key Features

Supertags: Define schemas for notes via tags
Networked graph of ideas and tasks
Powerful search and dynamic filtering
Daily nodes for seamless capture
AI-powered tagging and content synthesis
Flexible layout and view options
Deeply integrated task management within the graph

Tana Use Cases

💡Dynamic Project & Task Management

A project manager uses a #task supertag with fields for 'Priority', 'Due Date', and 'Assignee'. They can now instantly view all tasks across 10 different projects in one consolidated list, filtered by priority, while still keeping the tasks in their original contextual notes.

💡High-Fidelity Content Pipeline

A content creator uses a #content-idea tag and a #published-post tag. They can move an idea through a pipeline by simply changing its tag, while the supertag ensures that each stage (Idea -> Draft -> Review -> Published) has the required fields and checklists.

💡Personalized Research Database

A researcher defines a #source supertag with fields for 'Author', 'URL', and 'Key Takeaway'. Every time they find a new paper, they tag it. Tana automatically organizes these into a searchable library where they can find all sources related to a specific 'Concept' tag instantly.
