A side-by-side comparison of Strata and Tana on pricing, features, and fit, so you can decide which is right for you.
Quick answer
Strata and Tana are both strong choices, but they fit different needs. Choose Strata if you mainly need engineering teams maintaining living technical documentation that ai agents keep up to date — its edge is purpose-built for the ai agent era with native mcp support out of the box. Choose Tana if you need researchers building a connected, queryable knowledge base from papers, notes, and ideas — its edge is supertag system offers unmatched flexibility for structuring complex, relational information. Strata starts at Pricing available on request; Tana starts at Plus plan at $10/month (or $8/month billed annually), includes 2,000 AI credits.

- Auditable and reversible agent actions to maintain oversight and safety
- Real-time markdown editing with collaborative team support
- Supertag system for creating typed, relational data structures across your entire workspace
- Built-in AI meeting transcription and voice note capture for hands-free information collection
- Knowledge graph that connects nodes across notes, tasks, contacts, and projects automatically
- AI-assisted structured capture that surfaces patterns and helps you query your workspace intelligently
Pros & cons
- Purpose-built for the AI agent era with native MCP support out of the box
- Reversible agent actions provide safety and confidence when granting AI write access
- Filesystem-mount design makes it compatible with existing developer workflows and tooling
- Pricing is not publicly listed, making it hard to evaluate costs without contacting sales
- Highly specialized for agent-driven workflows, which may be overkill for teams not yet using AI agents
- Supertag system offers unmatched flexibility for structuring complex, relational information
- Native AI features for transcription and voice notes reduce manual data entry significantly
- Deep linking between nodes creates a truly connected knowledge graph rather than isolated documents
- Steep learning curve makes onboarding difficult for users new to knowledge graph concepts
- Free tier is limited to 1,000 nodes, which can be restrictive for heavy or long-term use
