Tana

What is Tana?

Tana is an AI-native knowledge management platform that reimagines the way individuals and teams capture, organize, and connect information. Unlike traditional note-taking apps that rely on folders and documents, Tana uses a graph-based structure where every piece of information — notes, tasks, people, projects, and ideas — exists as a node that can be connected to any other node. The AI is baked into the core experience, powering smart capture, automatic tagging, relationship suggestions, and natural language queries. As reviewed by PureAINav, Tana represents a new category of productivity tools that combine the flexibility of Notion, the structure of Roam Research, and the task management of Linear into a single, AI-powered workspace. The platform uses a unique supertag system that allows users to define custom types, fields, and relationships for any piece of information, creating a personalized knowledge graph.

Key Features

• Graph-Based Knowledge Base: Every piece of information is a node that can be connected bidirectionally, creating a rich web of knowledge rather than a folder hierarchy
• AI-Powered Smart Capture: Natural language input that automatically tags, categorizes, and links new information as it is captured, reducing manual organization
• Supertags: Customizable type system that defines fields, relationships, and behaviors for different kinds of information, from contacts to projects to book notes
• Natural Language Query: Ask questions in plain English and Tana surfaces relevant information from across your knowledge graph, powered by AI
• Task Management: Built-in task tracking with status, priority, due dates, and dependencies, all integrated with your knowledge graph
• Daily Notes: Automatic daily note creation with AI-generated summaries of what you worked on, connected to the relevant nodes in your graph
• Collaboration: Share nodes, workspaces, and knowledge graphs with team members for collaborative knowledge management

Who Should Use Tana

Tana is ideal for knowledge workers, researchers, and information-intensive professionals who need to manage complex, interconnected information. Product managers and engineers who deal with constantly evolving requirements and dependencies will benefit from the graph-based structure. Researchers and academics who need to connect ideas across papers, notes, and projects will find that Tana bidirectional linking is transformative. The learning curve is steeper than traditional note-taking apps, so Tana is best suited for users who are willing to invest time in learning the system in exchange for long-term productivity gains. Users who prefer simple, folder-based organization may find Tana overly complex.

Pricing

Tana is currently in beta with a free tier available for individual users. Paid plans are expected to launch with the general release. The free beta includes full access to all features, including the AI-powered smart capture and natural language query. There is no current limit on the number of nodes or storage. Tana has indicated that future pricing will be subscription-based, with a free tier for individuals and paid plans for teams and enterprises. The beta period is an excellent opportunity to build a comprehensive knowledge graph before the paid tiers launch.

Pros & Cons

Pros: Revolutionary graph-based approach to knowledge management, deeply integrated AI that genuinely improves the capture and organization workflow, supertag system is incredibly powerful once learned, natural language query makes information retrieval effortless, excellent for connecting complex interdisciplinary information.

Cons: Steep learning curve compared to traditional note-taking apps, still in beta with occasional bugs and missing features, no mobile app yet, export options are limited, the flexibility can be overwhelming for users who prefer structured workflows.

Alternatives

Notion: More mature with better collaboration features and templates but less powerful for interconnected knowledge. Roam Research: Similar graph-based approach with stronger emphasis on academic research but less AI integration. Obsidian: Excellent for local-first markdown-based knowledge management with a mature plugin ecosystem. Curated by PureAINav — PureAINav.com.
