Circle vs Double: at a glance
What is Circle?
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.
What is Double?
Double turns a recorded Chrome session into an agent that repeats the task.
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.

Circle
2.5COLLAB
Circle moves from building the community to selling inside it, with upsells and attribution.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Double
8.8COLLAB
Double turns a recorded Chrome session into an agent that repeats the task.
◆ Current state
Double is an accounting-practice platform built around the Ask Double assistant. Autoclose, an October 29 add-on at $500 a month, lets agents run the month-end close, and November 5 extended Ask Double to allocations, bank matching and 1099 prep. The November 12 release lets accountants record a task in the Double Chrome extension and turn it into an agent, adds bank feeds for US Xero clients, per-user caps on AI credits and new permission choices for agent actions.
◆ Where it's heading
Double is moving from an assistant that answers to agents that do recurring work, and is now letting firms create those agents by showing rather than configuring. Usage caps, permission levels and a web-browsing switch that is off by default show it adding controls as agents get more reach.
◆ Prediction
Expect more agent templates and recorder support for other client systems, plus wider Xero coverage after the US bank feeds launch.
