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

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
