AFFiNE vs Capacities

AFFiNE vs Capacities: at a glance
What is AFFiNE?
AFFiNE breaks a run of dependency-only canaries with a fix for blob uploads after quota changes.
AFFiNE is a collaborative workspace (docs, whiteboard, knowledge base) shipping canary builds across cloud, self-hosted Docker and native iOS/Mac apps. After five canaries of dependency work (piscina security patch, Node.js 22.23.3, Swift EventSource, ESLint v10, a broad dependency refresh), canary.921 fixes server-side blob sync: uploads read the current workspace storage limit, cancellation only hits the matching upload, and failed storage reservations retry more reliably. Before that came a stable iOS Share Extension, MCP Server visibility tied to Copilot, and config-driven OAuth and payment settings.
What is Capacities?
Capacities ships API 2.0, pivoting from self-contained PKM toward a connected AI memory layer
Capacities is a structured personal knowledge management tool shipping at monthly cadence. In the past 4 months it has added AI Chat Connectors (connecting the space to ChatGPT, Claude, and Cursor), a developer-facing API 2.0, weblink reader and analysis, PDF annotations, AI image generation, and configurable AI model providers. The combination describes a product moving from self-contained PKM to a node in a broader AI-augmented knowledge graph.

◆ Current state
AFFiNE is a collaborative workspace (docs, whiteboard, knowledge base) shipping canary builds across cloud, self-hosted Docker and native iOS/Mac apps. After five canaries of dependency work (piscina security patch, Node.js 22.23.3, Swift EventSource, ESLint v10, a broad dependency refresh), canary.921 fixes server-side blob sync: uploads read the current workspace storage limit, cancellation only hits the matching upload, and failed storage reservations retry more reliably. Before that came a stable iOS Share Extension, MCP Server visibility tied to Copilot, and config-driven OAuth and payment settings.
◆ Where it's heading
The canary channel is moving from toolchain housekeeping back to product fixes, starting with storage and sync correctness on the server. The three active lines remain mobile capture, making Copilot and MCP switchable per deployment, and getting quota, payment and auth behaviour right for self-hosted and cloud workspaces.
◆ Prediction
A stable release bundling the iOS Share Extension and the recent storage fixes is the most likely next visible move; the entries don't show its timing.

Capacities ships API 2.0, pivoting from self-contained PKM toward a connected AI memory layer
◆ Current state
Capacities is a structured personal knowledge management tool shipping at monthly cadence. In the past 4 months it has added AI Chat Connectors (connecting the space to ChatGPT, Claude, and Cursor), a developer-facing API 2.0, weblink reader and analysis, PDF annotations, AI image generation, and configurable AI model providers. The combination describes a product moving from self-contained PKM to a node in a broader AI-augmented knowledge graph.
◆ Where it's heading
The consistent direction is making Capacities connectable — first via AI chat integrations, then a proper developer API, and now deeper object types and AI media generation. The new Pro+/Believer+ pricing add-ons indicate AI usage is growing enough to require metered capacity. The platform is accumulating capability surface faster than a traditional note-taking tool and faster than comparable PKM competitors.
◆ Prediction
The most likely next move is deeper API-to-AI-connector integration, letting third-party agents create and modify Capacities objects programmatically — the existing connector work is the precondition for functioning as an AI memory layer rather than just a note store.
