Capacities vs Notion
A side-by-side editorial comparison of Capacities and Notion — release velocity, themes, recent moves, and the top alternatives to consider.
Capacities vs Notion: at a glance
What is Capacities?
Capacities is becoming an AI-connected knowledge hub with a real developer API.
Capacities, a note-and-object-based personal knowledge tool, is shipping fast — roughly biweekly releases — and pushing two frontiers at once: opening the app to outside systems and deepening its own AI. It now has AI Chat Connectors to ChatGPT, Claude, and Cursor, an on-device Search 3.0, image analysis, recurring tasks, and a choice of AI model provider.
What is Notion?
Notion is turning itself into the place teams and their AI agents share one board.
Notion has moved well past docs-and-databases into an agent platform. Its 3.5 and 3.6 releases stood up a full developer platform — a hosted Workers runtime, a CLI, and an External Agents API — then wired Claude, Cursor, and Codex into shared boards where teammates can @-mention them. AI Meeting Notes with speaker labels, Microsoft file read/write, and Outlook control round out a workspace being rebuilt around agents doing real work.
Capacities vs Notion: editorial side-by-side
Capacities
6.3COLLAB
Capacities is becoming an AI-connected knowledge hub with a real developer API.
◆ Current state
Capacities, a note-and-object-based personal knowledge tool, is shipping fast — roughly biweekly releases — and pushing two frontiers at once: opening the app to outside systems and deepening its own AI. It now has AI Chat Connectors to ChatGPT, Claude, and Cursor, an on-device Search 3.0, image analysis, recurring tasks, and a choice of AI model provider.
◆ Where it's heading
The arc is Capacities moving from a closed personal tool toward a platform: API 2.0 gives developers programmatic access, while the AI Chat Connectors let external assistants read and increasingly write into a user's space. Its AI work emphasizes user control — local-first search, choose-your-model — rather than a single hosted assistant. Cadence is high and consistent.
◆ Prediction
With the API opened and connectors moving from read to write, the likely next step is a richer integration surface — third-party tools and agents building on the API — plus more of what connected AI apps can create inside a space.
Notion
6.3PMCOMMS
Notion is turning itself into the place teams and their AI agents share one board.
◆ Current state
Notion has moved well past docs-and-databases into an agent platform. Its 3.5 and 3.6 releases stood up a full developer platform — a hosted Workers runtime, a CLI, and an External Agents API — then wired Claude, Cursor, and Codex into shared boards where teammates can @-mention them. AI Meeting Notes with speaker labels, Microsoft file read/write, and Outlook control round out a workspace being rebuilt around agents doing real work.
◆ Where it's heading
The direction is orchestration: Notion wants to be the surface where human and machine work sit side by side, with agents assignable like teammates and extensible through customer-written Workers. Each recent release deepens that bet — mobile agents, more model choices, new MCP connections, and admin controls for spend and audit. The note-taking product is now the on-ramp, not the point.
◆ Prediction
Expect the External Agents roster to expand beyond Claude, Cursor, and Codex, and Workers to move from free beta to credit-metered billing on the announced August 11, 2026 date.
