ReadMe vs Capacities
A side-by-side editorial comparison of ReadMe and Capacities — release velocity, themes, recent moves, and the top alternatives to consider.
ReadMe vs Capacities: at a glance
What is ReadMe?
ReadMe rebuilt itself around an MDX editor and docs-as-code GitHub sync
ReadMe has come through a ground-up rebuild. The product now centers on an MDX-backed editor with live preview, bi-directional GitHub sync, and the ability to build reusable interactive components (graphs, buttons, steppers) styled with Tailwind. The most recent posts are component-building tutorials, which signals the rebuilt platform is in the hands of users and being documented for real use.
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.

ReadMe rebuilt itself around an MDX editor and docs-as-code GitHub sync
◆ Current state
ReadMe has come through a ground-up rebuild. The product now centers on an MDX-backed editor with live preview, bi-directional GitHub sync, and the ability to build reusable interactive components (graphs, buttons, steppers) styled with Tailwind. The most recent posts are component-building tutorials, which signals the rebuilt platform is in the hands of users and being documented for real use.
◆ Where it's heading
The direction is unambiguous: ReadMe is moving from a hosted docs CMS toward a developer-native, code-first documentation platform. MDX plus GitHub sync makes docs behave like source, and custom components turn static reference pages into interactive surfaces. The progression from the 'Refactored' announcement to hands-on component guides shows the platform maturing from launch into adoption.
◆ Prediction
Expect ReadMe to keep building out the custom-component and docs-as-code story — more component primitives, deeper Git workflow support, and tooling that leans into the interactive-API-reference angle. The interview and explainer posts suggest a continued developer-experience marketing push alongside the feature work.
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.
