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.
What is Whimsical?
Whimsical rebuilt itself as a diagramming surface agents can drive, then went back to polishing the canvas
The agent work landed in two steps: April put Whimsical inside ChatGPT and shipped a remote MCP server reachable from Claude, Cursor and other agents without the desktop app; July shipped Ask Whimsical, an in-product AI agent that creates diagrams, wireframes and mind maps and searches the workspace. Since then the releases have gone back to craft — dark mode across whiteboarding and embeds, Turbopuffer-backed search, icons inside flowchart shapes, snappier elbow connectors, SVG export and a Linux desktop app. MCP coverage keeps widening, most recently to editable doc tables.

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.

6.3COLLAB
Whimsical rebuilt itself as a diagramming surface agents can drive, then went back to polishing the canvas
◆ Current state
The agent work landed in two steps: April put Whimsical inside ChatGPT and shipped a remote MCP server reachable from Claude, Cursor and other agents without the desktop app; July shipped Ask Whimsical, an in-product AI agent that creates diagrams, wireframes and mind maps and searches the workspace. Since then the releases have gone back to craft — dark mode across whiteboarding and embeds, Turbopuffer-backed search, icons inside flowchart shapes, snappier elbow connectors, SVG export and a Linux desktop app. MCP coverage keeps widening, most recently to editable doc tables.
◆ Where it's heading
Whimsical is treating the agent as a second class of user with the same rights as a person: everything reachable in the UI is progressively becoming reachable over MCP, and the doc tables becoming editable rather than readable is the tell. Meanwhile the human-facing work targets the reasons people leave a diagramming tool — search that finds things across a large workspace, exports that survive the trip elsewhere, and a canvas that is comfortable to sit in for hours. The two tracks are not competing for the same roadmap slots, which suggests both are considered core.
◆ Prediction
Expect MCP write coverage to keep expanding toward boards and wireframes, matching what Ask Whimsical can already do in-product, and for the ChatGPT integration to be joined by equivalents in other assistant surfaces given the remote MCP server already makes that cheap.
