Circle vs SiYuan: at a glance
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 SiYuan?
SiYuan's 3.8.8 alphas keep layering database automation and editor polish on Gemini support.
SiYuan cycled 3.8.7 through four beta respins, then opened 3.8.8 with a long alpha.1: Gemini Interactions API support, automation that collects blocks into databases, tab-to-mind-map conversion, compact desktop mode and many editor refinements. Alpha.2 upgraded Electron and fixed Linux OCR and proxy detection, and alpha.3 added template-based field assignments in database automations and configurable embedding batching. Alpha.4 adds block indicator hierarchy, closer mobile table parity and multiple mind-map connector styles.

Circle

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.

SiYuan's 3.8.8 alphas keep layering database automation and editor polish on Gemini support.
◆ Current state
SiYuan cycled 3.8.7 through four beta respins, then opened 3.8.8 with a long alpha.1: Gemini Interactions API support, automation that collects blocks into databases, tab-to-mind-map conversion, compact desktop mode and many editor refinements. Alpha.2 upgraded Electron and fixed Linux OCR and proxy detection, and alpha.3 added template-based field assignments in database automations and configurable embedding batching. Alpha.4 adds block indicator hierarchy, closer mobile table parity and multiple mind-map connector styles.
◆ Where it's heading
AI is moving from a side panel into the workspace's own controls, and model choice is widening beyond ChatGPT to Gemini. Databases keep gaining structure and automation, while editor polish arrives in large cumulative batches. Four alphas in three days with mostly cumulative notes suggest 3.8.8 is being stabilised in public.
◆ Prediction
Expect further 3.8.8 alphas with small editor and mobile additions, then a beta; the entries don't show whether 3.8.7 gets a stable tag first.
