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.

What is Kavita?

Kavita overhauls its Kavita+ premium tier and integrates Hardcover for book recommendations, its most significant monetization move in three years.

Kavita v0.9.1 delivers a complete redesign of Kavita+, the platform's premium subscription layer. The Hardcover integration — adding OAuth login and recommendation support — arrived alongside Hardcover's own launch of OAuth and Vibes recommendations, with v0.9.1.4 required to enable recommendations. The 50x scanner performance improvement from v0.8.9 continues to pay dividends for large libraries.

Capacities vs Kavita: editorial side-by-side

C5.0

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.

6.3

Kavita overhauls its Kavita+ premium tier and integrates Hardcover for book recommendations, its most significant monetization move in three years.

◆ Current state

Kavita v0.9.1 delivers a complete redesign of Kavita+, the platform's premium subscription layer. The Hardcover integration — adding OAuth login and recommendation support — arrived alongside Hardcover's own launch of OAuth and Vibes recommendations, with v0.9.1.4 required to enable recommendations. The 50x scanner performance improvement from v0.8.9 continues to pay dividends for large libraries.

◆ Where it's heading

The Kavita+ overhaul repositions the premium tier from a metadata downloader into a connected reading ecosystem. Hardcover integration is the first external service partnership for Kavita+, suggesting the project is moving beyond a standalone reader toward a recommendation and discovery layer. The recurring pattern of epub reader and reading experience improvements reflects a platform that has matured past basic library management.

◆ Prediction

Kavita will deepen the Hardcover integration with additional recommendation signals and expand Kavita+ to include connections to other reading platforms — likely Anilist or similar — as the subscription layer evolves from metadata tools to a reading discovery platform.
