Interact
Interact opens its intranet to outside AI assistants and uses Claude to attack its own platform.
A side-by-side editorial comparison of Circle and SiYuan — release velocity, themes, recent moves, and the top alternatives to consider.
Circle moves from building the community to selling inside it, with upsells and attribution.
Circle's September and October releases shift weight from AI building to revenue and live engagement. October adds post-checkout upsells that charge only the difference, GA4 and Meta conversion tracking on paywalls, and an attribution tab showing the revenue behind every checkout link. September added breakout rooms for up to 10 groups, six more reaction types and custom gamification points. Paywalls, subscriptions and coupons also reached the Admin API and Circle MCP.
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.

June to August built the operating layer around Circle AI and the page builder; the two releases since instrument the money. Attribution and upsells answer what a page or checkout link actually earned, which completes the funnel the page builder opened. Taking Paywalls into Circle MCP keeps the agent path level with the human one.
Member reviews are announced for early November, with automatic prompts, rating trends and display on Discover and websites, so the next release is largely known. Further Paywalls coverage in Circle MCP is the likeliest follow-on.

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.
Expect more 3.8.11 alphas, then betas and release candidates with the same list, following the 3.8.10 pattern.
