Capacities vs AFFiNE: at a glance
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.
What is AFFiNE?
AFFiNE is building import on-ramps off Notion and OneNote while stabilizing iOS.
AFFiNE ships a fast canary stream alongside a 0.27 beta line. The recent arc centers on migration on-ramps — a OneNote importer and Notion Markdown zip imports that resolve internal links into linked pages — plus iOS stabilization and a nodemailer security bump. The newest release is a batch of iOS keyboard, image-picker, and scrolling fixes.

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.
AFFiNE

AFFiNE is building import on-ramps off Notion and OneNote while stabilizing iOS.
◆ Current state
AFFiNE ships a fast canary stream alongside a 0.27 beta line. The recent arc centers on migration on-ramps — a OneNote importer and Notion Markdown zip imports that resolve internal links into linked pages — plus iOS stabilization and a nodemailer security bump. The newest release is a batch of iOS keyboard, image-picker, and scrolling fixes.
◆ Where it's heading
The importer investment reads as a deliberate play to lower switching costs from Notion and OneNote, the two incumbents AFFiNE competes with for knowledge-base users. Alongside it, the team is hardening the mobile client and terminology (cloud → sync/self-hosted), signaling a push toward production readiness across platforms.
◆ Prediction
Expect more importer coverage and continued iOS/desktop polish as 0.27 moves toward a stable release. The link-resolution work suggests deeper fidelity for migrated workspaces next.
