What is Nuclino?

Nuclino's October drop turns to mobile and content blocks after three MCP-focused releases.

Nuclino ships a feature roundup roughly every quarter. The October 26 release covers mobile app improvements, more highlight colors and audio blocks; the feed carries only the title, so details aren't visible. The three releases before it, January through September, each extended its MCP server and API access for AI assistants.

What is SiYuan?

SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.

SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

Nuclino vs SiYuan: editorial side-by-side

2.5

Nuclino's October drop turns to mobile and content blocks after three MCP-focused releases.

◆ Current state

Nuclino ships a feature roundup roughly every quarter. The October 26 release covers mobile app improvements, more highlight colors and audio blocks; the feed carries only the title, so details aren't visible. The three releases before it, January through September, each extended its MCP server and API access for AI assistants.

◆ Where it's heading

After a year where MCP access was the recurring thread, the latest drop goes back to editor and mobile basics. Nuclino looks to alternate between the AI-assistant access layer and core editing features rather than going all-in on either.

◆ Prediction

The quarterly rhythm points to the next roundup around late January 2027. Whether MCP returns as a headline item there is unclear from these entries.

SiYuan 3.8.9 reaches RC, adding AI-agent extraction of images embedded in PDFs.

◆ Current state

SiYuan moved 3.8.9 from beta.6 to rc.1 on Oct 28. The RC's only new item is AI-agent extraction of images embedded in PDFs; the rest of its long list matches beta.5's cumulative notes: pinned agent sessions, backlink filtering by database fields, block-reference collection through database automation, resizable table rows, mind-map themes and node copy/paste, TIFF previews and macOS proxy detection.

◆ Where it's heading

The 3.8.x line keeps turning databases and mind maps into structured tools that act on the block graph, and the built-in agent is gaining reach into document content such as PDFs. The release cadence is fast and noisy, with most builds repeating the same cumulative notes.

◆ Prediction

A stable 3.8.9 is likely within days, with little added beyond fixes now that it has reached RC.
