What is Outline?
Outline adds personal docs even admins can't open, pairing agent access with user privacy.
Outline ships on two tracks: an agent integration surface (April's MCP editing tools, September's browser-native WebMCP) and steady workspace UX work. The October release gives every member a Personal sidebar section for drafts and notes that no one else can see, admins included. That is a notable stance for a team wiki, where admin visibility is usually the default.
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.

Outline

Outline adds personal docs even admins can't open, pairing agent access with user privacy.
◆ Current state
Outline ships on two tracks: an agent integration surface (April's MCP editing tools, September's browser-native WebMCP) and steady workspace UX work. The October release gives every member a Personal sidebar section for drafts and notes that no one else can see, admins included. That is a notable stance for a team wiki, where admin visibility is usually the default.
◆ Where it's heading
Outline is building toward an agent-accessible knowledge base that individuals also use for private work, not only shared documentation. MCP and WebMCP opened the content to agents, Open Knowledge Format export lowered lock-in, and personal documents pull pre-publication drafting into the product. The pattern is to widen what lives in Outline while giving users clear control over who, or what, can reach it.
◆ Prediction
The next likely move is connecting personal documents to the existing flows, for example promoting a personal draft into a shared collection or defining what the MCP tools can see in personal space. The entries don't show how agent access and personal privacy will interact, and that is the open question.
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.
