What is Circle?

Circle rebuilt itself around an AI that runs the community, and now builds its landing pages too.

Circle ships a dated monthly release covering web, iOS, Android and its branded-app product, and the last six months have all pointed one direction. Circle Eclipse, announced in June and opened to every customer in late July, re-skinned both member and admin surfaces and brought an AI layer with memory, roughly fifty domain-specific skills and project workspaces. August extends that AI outward: it now builds complete pages from a prompt or an existing URL — homepages, sales pages, event pages in the operator's brand — generating copy and images and running SEO audits inside the builder. The rest of the release is retention plumbing: a Get Started onboarding checklist on web and mobile, live emoji reactions in chats and rooms, customizable member directory filters, and native mobile video recording.

What is Double?

Double's AI assistant reaches past QuickBooks into Xero.

Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 15 release puts Ask Double on Xero clients in a read-only beta and adds Consolidations, a beta for multi-entity QBO clients with account mapping and elimination rules. It follows Connectors opening to any MCP server and invoices gaining tax, terms and custom fields.

Circle rebuilt itself around an AI that runs the community, and now builds its landing pages too.

◆ Current state

Circle ships a dated monthly release covering web, iOS, Android and its branded-app product, and the last six months have all pointed one direction. Circle Eclipse, announced in June and opened to every customer in late July, re-skinned both member and admin surfaces and brought an AI layer with memory, roughly fifty domain-specific skills and project workspaces. August extends that AI outward: it now builds complete pages from a prompt or an existing URL — homepages, sales pages, event pages in the operator's brand — generating copy and images and running SEO audits inside the builder. The rest of the release is retention plumbing: a Get Started onboarding checklist on web and mobile, live emoji reactions in chats and rooms, customizable member directory filters, and native mobile video recording.

◆ Where it's heading

The community platform keeps being reframed as a business-operations platform: Discover 2.0 supplies member demand, Circle AI does the structuring work, Circle Studios sells the operating labor outright. The page builder fills the one gap in that loop — the acquisition surface an operator previously built somewhere else — and shipping SEO audits with it says Circle intends to own how communities get found, not just how they run. Circle MCP in April remains the tell that the operator was always expected to be an agent. Underneath, the retention items this month are the unglamorous half of the same funnel argument.

◆ Prediction

The fifty Circle AI skills are the surface most likely to open next, either to operator-authored skills or to skills invoked through Circle MCP rather than only in the Circle UI. Expect page building and Discover to connect, so a generated sales page feeds the marketplace listing directly.

Double's AI assistant reaches past QuickBooks into Xero.

◆ Current state

Double is an accounting-practice platform built around QuickBooks Online, with the Ask Double assistant at its centre. The October 15 release puts Ask Double on Xero clients in a read-only beta and adds Consolidations, a beta for multi-entity QBO clients with account mapping and elimination rules. It follows Connectors opening to any MCP server and invoices gaining tax, terms and custom fields.

◆ Where it's heading

Two tracks run in parallel: fuller QBO bookkeeping coverage, now including multi-entity consolidation, and an AI layer that reaches across a firm's tools. Xero support arriving through Ask Double first, read-only, shows the assistant is the wedge for expanding beyond the QBO ledger.

◆ Prediction

Expect Ask Double on Xero to gain write actions after the read-only beta, and Consolidations to stay a Scale-tier feature. Whether Xero gets the full close workflow is not shown in the entries.
