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 restructures AI pricing with a 93%-cheaper Standard tier, making Ask Double viable at full-book scale

Double is an AI-first accounting platform built for accounting firms managing multiple clients. Over the past two months the product has aggressively extended its Ask Double AI assistant — building workpapers, importing accruals, managing metrics, routing bank transactions from raw PDFs, and now auto-routing queries across a three-tier model stack. The Sep 10 model restructuring is the culmination: with a Standard tier 93% cheaper than Expert and an Auto mode that routes per-query complexity, Double has shifted AI accounting from a premium add-on into an economically viable default across every client account. The interactive financial statement suite — P&L, Balance Sheet, and Cash Flow — is now complete.

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 restructures AI pricing with a 93%-cheaper Standard tier, making Ask Double viable at full-book scale

◆ Current state

Double is an AI-first accounting platform built for accounting firms managing multiple clients. Over the past two months the product has aggressively extended its Ask Double AI assistant — building workpapers, importing accruals, managing metrics, routing bank transactions from raw PDFs, and now auto-routing queries across a three-tier model stack. The Sep 10 model restructuring is the culmination: with a Standard tier 93% cheaper than Expert and an Auto mode that routes per-query complexity, Double has shifted AI accounting from a premium add-on into an economically viable default across every client account. The interactive financial statement suite — P&L, Balance Sheet, and Cash Flow — is now complete.

◆ Where it's heading

Double is building toward a full AI-agent accounting platform, not just a chat interface bolted onto bookkeeping software. The AI Agents private beta (automating recurring tasks on a schedule or event trigger), the MCP/API surface for programmatic control, and the Connections feature (reaching into Slack, Notion, HubSpot) all point to Double becoming an orchestration layer for accounting firms. The model pricing restructure signals that Ask Double is expected to run on virtually every client action, with human review reserved for exceptions rather than the default. The direction is clear: make AI the primary work surface and treat the accounting firm's judgment as the final gate.

◆ Prediction

The next move is most likely graduating the AI Agents beta to general availability — converting scheduled automation and event-trigger workflows from a differentiated beta into a standard tier feature. Expansion of the Connections library beyond Slack, Notion, and HubSpot is also probable, since cross-tool context is a prerequisite for agents to make decisions autonomously.
