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 SiYuan?

SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0

SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.

Document360 vs SiYuan: editorial side-by-side

D6.3

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.

6.3

SiYuan stabilises 3.8.1 after a seven-build beta run, all of it widening the agent surface it opened in 3.8.0

◆ Current state

SiYuan has just cut 3.8.1 stable, the endpoint of a beta chain that ran six builds in five days. The release groups into three areas: AI integration work - custom editor actions syncing across devices, an Agent panel shortcut, user-level skills read from a shared agents directory, nested rerank API formats and OpenAI Responses API support; editing and database throughput, including virtualised grouped-table rendering and faster document loading; and cross-platform reliability covering HEIF/HEIC previews, PDF export and mobile behaviour. A batch of MCP and publishing-service fixes rounds it out.

◆ Where it's heading

This is consolidation of the surface 3.8.0 opened, not an extension of it. The agent, semantic search and MCP endpoint arrived in the 3.8.0 line; 3.8.1 makes them portable and pluggable - skills come from a directory the user controls, editor actions follow the user between devices, and the provider layer now speaks the OpenAI Responses API rather than one bespoke shape. The high beta count against a modest final diff shows a project stabilising a young subsystem rather than building a new one.

◆ Prediction

The next line most likely pushes on the skills directory - discovery, sharing or marketplace distribution of user-level skills - since that is the piece 3.8.1 made user-editable without giving it a distribution path.
