Interact vs SiYuan: at a glance
What is Interact?
Interact opens its intranet to outside AI assistants and uses Claude to attack its own platform.
Interact's October feed is led by Interact MCP, which brings the intranet into AI assistants people already use, with read and write access under each person's permissions. Its security team joined Anthropic's Cyber Verification Program and is testing its own platform with Claude Mythos 5.1, and Cyber Essentials certification now covers Interact and Sideways 6. The rest of the month is buyer guides, award news and thought leadership.
What is SiYuan?
SiYuan 3.8.11 alphas add freeform mind maps and plugin snapshots right after 3.8.10.
SiYuan pushed 3.8.10 through betas and release candidates between November 7 and 9, carrying workspace AI memory, database sub-items and a built-in Markdown editor. The 3.8.11 alphas followed within days: freeform mind map relationships with per-node connector styles, browsing and restoring plugin snapshots, excluding assets from cleanup, a built-in date picker and rich text in database primary keys. Alpha 4 adds search and replace in the standalone Markdown editor.
Interact vs SiYuan: editorial side-by-side
Interact
5.0COLLAB
Interact opens its intranet to outside AI assistants and uses Claude to attack its own platform.
◆ Current state
Interact's October feed is led by Interact MCP, which brings the intranet into AI assistants people already use, with read and write access under each person's permissions. Its security team joined Anthropic's Cyber Verification Program and is testing its own platform with Claude Mythos 5.1, and Cyber Essentials certification now covers Interact and Sideways 6. The rest of the month is buyer guides, award news and thought leadership.
◆ Where it's heading
The Spring Action Agent work put agents inside the intranet; MCP moves the intranet out to wherever employees already work. That raises the stakes on trust, which is why the security items matter more than they would alone: a system holding company knowledge is being opened to more clients. The company's content messaging now describes the intranet as adaptive.
◆ Prediction
Expect Conductor and MCP connections to reach more business systems, following the Workday pattern from the Spring Launch. Further security attestations are also likely as AI access expands.
SiYuan
5.0COLLAB
SiYuan 3.8.11 alphas add freeform mind maps and plugin snapshots right after 3.8.10.
◆ Current state
SiYuan pushed 3.8.10 through betas and release candidates between November 7 and 9, carrying workspace AI memory, database sub-items and a built-in Markdown editor. The 3.8.11 alphas followed within days: freeform mind map relationships with per-node connector styles, browsing and restoring plugin snapshots, excluding assets from cleanup, a built-in date picker and rich text in database primary keys. Alpha 4 adds search and replace in the standalone Markdown editor.
◆ Where it's heading
SiYuan works in fast public cycles, with the next version's alphas starting as soon as the last one stabilises. 3.8.11 is about polish and editing depth: mind maps, databases and the new Markdown editor all get more control.
◆ Prediction
Expect more 3.8.11 alphas, then betas and release candidates with the same list, following the 3.8.10 pattern.
