What is Capacities?
Capacities pairs an AI-connected knowledge hub with a real developer API.
Capacities has spent 2026 turning a personal knowledge tool into an AI-connected, programmable workspace. The past two months shipped API 2.0 for developers, AI Chat Connectors that let ChatGPT, Claude, and Cursor create and edit objects, plus steady polish across the editor, dates, and presentation mode. The newest release is a reliability roundup rather than a feature push.
What is Document360?
Document360 rebuilt its API for agents; now it's turning the AI inward on authoring.
Monthly point releases on a steady 12.x line, each a themed bundle rather than a fix list. The last three releases rebuilt the developer-facing surface: an interactive API reference with an in-page Try It! console, a ground-up API v3 with OAuth 2.0 and scoped keys, and a Widget 2.0 embedding architecture now rolling out with a migration deadline. Around that, Eddy AI and the MCP server have been gaining governance controls — reader-group restrictions, workflow permissions, usage analytics — more often than new capabilities.

Capacities
6.3COLLAB
Capacities pairs an AI-connected knowledge hub with a real developer API.
◆ Current state
Capacities has spent 2026 turning a personal knowledge tool into an AI-connected, programmable workspace. The past two months shipped API 2.0 for developers, AI Chat Connectors that let ChatGPT, Claude, and Cursor create and edit objects, plus steady polish across the editor, dates, and presentation mode. The newest release is a reliability roundup rather than a feature push.
◆ Where it's heading
The direction is consistent: make a user's space reachable from both AI assistants and code, then harden it. Capability drops (API, connectors, bulk import, image analysis) now alternate with polish passes that stabilize the surface just expanded. Presentation mode is quietly maturing from a side feature into a first-class output.
◆ Prediction
Next likely move is deeper API coverage or an AI-connector upgrade that writes richer object types — extending the programmable surface it just opened rather than adding a net-new pillar.
Document360
6.3COLLAB
Document360 rebuilt its API for agents; now it's turning the AI inward on authoring.
◆ Current state
Monthly point releases on a steady 12.x line, each a themed bundle rather than a fix list. The last three releases rebuilt the developer-facing surface: an interactive API reference with an in-page Try It! console, a ground-up API v3 with OAuth 2.0 and scoped keys, and a Widget 2.0 embedding architecture now rolling out with a migration deadline. Around that, Eddy AI and the MCP server have been gaining governance controls — reader-group restrictions, workflow permissions, usage analytics — more often than new capabilities.
◆ Where it's heading
Two threads run through the year. One makes the knowledge base machine-readable and machine-writable: MCP server, automatic llms.txt, open-an-article-in-ChatGPT-or-Claude, then API v3. The other fences that access with admin controls before enterprise buyers have to ask. The newest release turns the AI inward for the first time — the redesigned Publish dialog puts suggestions and validation in the author's path rather than the reader's, which is a different customer for the same capability.
◆ Prediction
The AI suggestions now sitting in the Publish dialog are the obvious candidate to move into the editor itself, and the advanced v3 endpoints sold as an add-on look like the seed of a higher API tier. The Widget 2.0 forced migration is the near-term execution risk, since it puts required technical work on existing customers to a fixed timeline.
