Tana
4.3
Tana stores meeting notes, internal wiki pages and tasks as the same structured data, so a note can be a task and a project page at once rather than being copied between three tools. It supports MCP, which lets AI assistants read and write that structure directly.

What it is good for
- Teams whose notes, wiki and tasks currently live in three tools
- Capturing meetings as structured data rather than prose
- Workflows where the same item has several roles
- Connecting an AI assistant to an internal knowledge base
Strengths and trade-offs
Strengths
- One structured store behind notes, wiki and tasks
- Supertags make structure emerge from use rather than upfront design
- MCP support for AI assistants
- Meeting capture that produces data, not just text
Trade-offs
- Steep learning curve; the model has to be understood first
- Hard to adopt across a team that wants a simple document
- Migrating existing notes is substantial work
Editors' review
One structure behind the notes, the wiki and the tasks
The usual arrangement has meeting notes in one tool, the wiki in another, tasks in a third, and the same information copied between them going stale at different rates. Tana's premise is one structured store where an item can be all three.
MCP support makes that structure reachable by an assistant, which is where it gets genuinely interesting — a knowledge base an AI can query is worth more than one a person has to search.
The cost is the learning curve. Tana requires understanding its model before it is useful, which is a hard sell to colleagues who want to write a document. It rewards teams willing to invest; it frustrates everyone else.
Verdict
Powerful for structured thinkers and teams willing to learn it. Not a drop-in replacement for a document tool.
