Object-based note-taking and personal knowledge management app

Capacities pairs an AI-connected knowledge hub with a real developer API.

pkmai-connectorsdeveloper-apipresentation-modepolishcollaboration
◆Current state
Capacities has spent 2026 turning a personal knowledge tool into an AI-connected, programmable workspace. The past two months shipped API 2.0 for developers, AI Chat Connectors that let ChatGPT, Claude, and Cursor create and edit objects, plus steady polish across the editor, dates, and presentation mode. The newest release is a reliability roundup rather than a feature push.
◆Where it's heading
The direction is consistent: make a user's space reachable from both AI assistants and code, then harden it. Capability drops (API, connectors, bulk import, image analysis) now alternate with polish passes that stabilize the surface just expanded. Presentation mode is quietly maturing from a side feature into a first-class output.
◆Prediction
Next likely move is deeper API coverage or an AI-connector upgrade that writes richer object types — extending the programmable surface it just opened rather than adding a net-new pillar.

    Reliability polish across dates, tabs, editor, and presentation mode

    A polish and reliability roundup (v1.67.13) following the heavier API 2.0 release: steadier date editing, smoother side-panel gestures, a restored shortcut, and presentation mode that now handles daily notes and media with continuous list numbering. This is the harden-what-you-just-shipped half of the product's cadence.

    ⚡ SPARK

    API 2.0 introduces 'Capacities for developers,' turning the note tool into something you can build on top of, bundled with weblink analysis, reader view, and annotations. It is the code-facing complement to the AI connectors shipped weeks earlier.

    Recurring Tasks and Choose Your Capacities AI Model Provider

    Recurring tasks arrive with flexible scheduling and catch-up options, and users can now pick their own AI model provider. The provider choice is a notable nod toward user control over which model powers the assistant.
