A side-by-side editorial comparison of Tana and Notion — release velocity, themes, recent moves, and the top alternatives to consider.
Tana is rebuilding itself around meetings — capture, present, and AI wrap-up, all native
Tana, once a supertag-driven knowledge base, now spends nearly all its release energy on a meeting layer: a pre-meeting hub card, one-click capture of external Zoom/Teams/Meet calls through system audio, live document presentation, and AI agents that summarize and extract outcomes. The Today page has become the product's home surface, organizing the day around calls and their generated artifacts. Recent work is dense and iterative — join nudges, permission recovery, presentation palettes, voice agents — all pointed at the same target.
Notion is turning its workspace into an orchestration layer for external AI agents.
Notion has moved well past docs-and-wikis: the 3.5 Developer Platform and 3.6 release reposition it as an orchestration layer where external agents like Claude and Cursor, hosted Workers, and MCP connections do work alongside teams. Recent shipping is almost entirely agent infrastructure — shareable Workers, an agent-focused iOS app, calendar and Outlook control, and admin guardrails for spend and audit.

The direction is unambiguous: Tana wants to own the full arc of a meeting — before (hub, invites, calendar sync), during (capture, present, live AI digest), and after (summaries, outcomes, review queue) — and fold the results back into its typed knowledge graph. External-meeting capture moving to on-by-default and live doc presentation without screen sharing put it in direct competition with Granola and Fellow, not just as a notes tool. The knowledge-base roots are increasingly the substrate that meeting outputs land in, not the headline.
Expect the next releases to deepen the AI wrap-up loop — richer automatic outcome extraction, agent actions triggered from meeting content, and tighter linking of meeting artifacts into typed entities — since that is the recurring thread across these entries.

The direction is consistent: own the surface where humans and agents collaborate, then meter it. Workers move to credit-based billing on August 11, the MCP connector list keeps expanding, and each new capability — more file types, calendar, external-agent orchestration — widens what an agent can do inside Notion rather than adding features for people directly.
Expect the Workers-to-credits cutover to anchor a usage-based pricing push, with more first-party MCP connectors and deeper external-agent orchestration as the next beats.
