Circle
Circle is turning its community platform into an AI-native OS, from prompt-built setups to MCP.
A side-by-side editorial comparison of CoScreen and AFFiNE — release velocity, themes, recent moves, and the top alternatives to consider.
CoScreen ships its final build and declares End of Life after a year of quiet.
CoScreen just shipped V8.11.14, explicitly labeled its final software update, alongside an official End of Life announcement. The last real feature release was V8.10 in August 2025 (screen-region sharing plus macOS Tahoe support); the eleven months since produced nothing but this shutdown notice. The multiplayer, multi-window screen-sharing tool for remote teams is being retired rather than iterated.
AFFiNE builds out MCP credential control while widening its Notion/OneNote import net.
AFFiNE, the open-source Notion-style workspace, ships near-daily canary builds alongside a 0.27 beta line. Recent work splits between data-import interoperability (OneNote, Notion markdown zips) and hardening its MCP layer with scoped, revocable workspace credentials. Mobile stabilization and i18n cleanup round out routine maintenance.

The multiplayer, multi-window screen-sharing tool for remote teams is being retired rather than iterated.
The cadence tells the story: steady usability and performance work through 2024 and into early 2025, a last genuine feature drop in August 2025, then silence until today's EOL. This is a sunset, not a pivot. Users can expect the app to keep running on 8.11.14 but to receive no further fixes or OS-compatibility updates.
With EOL declared and a final build shipped, the only moves left are wind-down mechanics: a hard shutdown date, export or migration guidance, and eventual removal from distribution. No further feature work is coming.
AFFiNE, the open-source Notion-style workspace, ships near-daily canary builds alongside a 0.27 beta line. Recent work splits between data-import interoperability (OneNote, Notion markdown zips) and hardening its MCP layer with scoped, revocable workspace credentials. Mobile stabilization and i18n cleanup round out routine maintenance.
Two threads are converging: making AFFiNE easy to move into (importers that pull content out of Notion and OneNote) and easy to program against (MCP credentials with read-only vs read/write scopes). The product is positioning as both a migration destination and an agent-addressable data store, not just an editor.
Expect the MCP credential management to graduate from canary into the stable 0.27 release, and the importer roster to keep expanding toward more third-party formats.
