What is Tana AI?

Tana is a knowledge management workspace designed for people who need to organise complex information and think through problems systematically. It combines a flexible database structure (using supertags) with AI capabilities to help you capture, organise, and connect ideas across research projects, writing, and learning. The tool sits between a traditional note-taking app and a full database system, offering more structure than free-form notes but more flexibility than rigid databases. It's particularly useful if you regularly work with interconnected information, conduct research, or need to maintain detailed project documentation.

Key Features

Supertags

customisable tags that can contain structured fields and metadata, allowing you to organise information in hierarchical ways

AI-assisted writing and research

built-in AI tools to help summarise, expand, and generate content within your workspace

Linked databases

create connections between different pieces of information to build knowledge networks

Templates

pre-built and custom templates to standardise how you capture and organise different types of information

Full-text search

find information across your entire workspace quickly

Collaborative features

share workspaces and collaborate with others in real-time

Pros & Cons

Advantages

  • More powerful than basic note-taking apps for managing complex, interconnected information
  • Freemium pricing lets you test the core functionality without commitment
  • Built-in AI features reduce manual summarisation and content generation work
  • Flexible structure means you can adapt it to your specific workflow rather than forcing your work into a rigid system

Limitations

  • The learning curve is steeper than simpler note-taking tools; understanding supertags and database relationships takes time
  • Pricing and feature limits for the free tier are not widely published, so budget planning requires checking their current offer
  • Less established than competitors like Notion or Obsidian, so you may find fewer templates and community resources online
