What is Tango?
Tango ships an MCP server, so AI assistants can answer from a team's captured workflows.
Tango captures browser workflows into step-by-step guides, and the Tango MCP, now live on Enterprise plans, lets teams query their Tango workspace from inside AI assistants. Before it, 2026 releases deepened the guide itself: voice narration during capture, branching, translations, video embeds, plus a September rebrand and edit-mode shortcuts.
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.

Tango
3.8COLLAB
Tango ships an MCP server, so AI assistants can answer from a team's captured workflows.
◆ Current state
Tango captures browser workflows into step-by-step guides, and the Tango MCP, now live on Enterprise plans, lets teams query their Tango workspace from inside AI assistants. Before it, 2026 releases deepened the guide itself: voice narration during capture, branching, translations, video embeds, plus a September rebrand and edit-mode shortcuts.
◆ Where it's heading
The MCP changes where Tango's content gets read: guides become a knowledge source for AI tools, not only pages people open. It is the first AI move in the feed since the April 2025 AI CRM Admin agent, and again gated to Enterprise, where governance and translations also landed.
◆ Prediction
The entry is short on scope, so it is unclear whether the MCP is read-only; a follow-up widening it to more plans or adding write actions such as creating guides would be the next signal.
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.
