Circle vs Memos
A side-by-side editorial comparison of Circle and Memos — release velocity, themes, recent moves, and the top alternatives to consider.
Circle vs Memos: 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 Memos?
Memos adopts calendar versions and rebuilds writing around one block editor.
Memos has moved to calendar versioning, with 26.10 candidates following 0.31 and versions now written YY.MM.N. 26.10.0-rc.2 replaces the editor with one block editor shared by writing and reading, and turns the instance-wide memo length and upload caps into ordered per-user usage limits that also cover memo count and total storage. rc.1 added editor suggestions and transcription of existing audio attachments, and Spaces now follow the user across Timeline, Calendar, Map and Attachments.

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.
Memos
5.0COLLAB
Memos adopts calendar versions and rebuilds writing around one block editor.
◆ Current state
Memos has moved to calendar versioning, with 26.10 candidates following 0.31 and versions now written YY.MM.N. 26.10.0-rc.2 replaces the editor with one block editor shared by writing and reading, and turns the instance-wide memo length and upload caps into ordered per-user usage limits that also cover memo count and total storage. rc.1 added editor suggestions and transcription of existing audio attachments, and Spaces now follow the user across Timeline, Calendar, Map and Attachments.
◆ Where it's heading
Spaces made Memos multi-user, and usage limits are what an administrator needs once several people share an instance. The candidate keeps spending compatibility to get there: upgrading signs everyone out because access tokens are bound to the password, and the old size settings are removed without migration, leaving defaults of 8 KiB per memo and 32 MiB per file. The HTTP layer also moved to the Go standard library, with operators asked to report reverse-proxy differences.
◆ Prediction
Expect 26.10.0 stable with those upgrade notes intact. Reverse-proxy reports against the new HTTP layer are the likeliest cause of another candidate.
