AFFiNE vs Capacities
A side-by-side editorial comparison of AFFiNE and Capacities — release velocity, themes, recent moves, and the top alternatives to consider.
AFFiNE vs Capacities: at a glance
What is AFFiNE?
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.
What is Capacities?
Capacities is becoming an AI-connected knowledge hub with a real developer API.
Capacities, a note-and-object-based personal knowledge tool, is shipping fast — roughly biweekly releases — and pushing two frontiers at once: opening the app to outside systems and deepening its own AI. It now has AI Chat Connectors to ChatGPT, Claude, and Cursor, an on-device Search 3.0, image analysis, recurring tasks, and a choice of AI model provider.
AFFiNE vs Capacities: editorial side-by-side
AFFiNE
5.0COLLAB
AFFiNE builds out MCP credential control while widening its Notion/OneNote import net.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Capacities
6.3COLLAB
Capacities is becoming an AI-connected knowledge hub with a real developer API.
◆ Current state
Capacities, a note-and-object-based personal knowledge tool, is shipping fast — roughly biweekly releases — and pushing two frontiers at once: opening the app to outside systems and deepening its own AI. It now has AI Chat Connectors to ChatGPT, Claude, and Cursor, an on-device Search 3.0, image analysis, recurring tasks, and a choice of AI model provider.
◆ Where it's heading
The arc is Capacities moving from a closed personal tool toward a platform: API 2.0 gives developers programmatic access, while the AI Chat Connectors let external assistants read and increasingly write into a user's space. Its AI work emphasizes user control — local-first search, choose-your-model — rather than a single hosted assistant. Cadence is high and consistent.
◆ Prediction
With the API opened and connectors moving from read to write, the likely next step is a richer integration surface — third-party tools and agents building on the API — plus more of what connected AI apps can create inside a space.
