Capacities is a note-taking app that organizes ideas as connected objects. See its features, AI assistant, and Free, Pro, and Believer pricing plans.
Capacities is a note-taking and personal knowledge management app built by Capacities Labs GmbH, founded in 2020 by Steffen Bleher and Michael von Hohnhorst and based in Sankt Wendel, Germany. Rather than storing information as generic pages or files, Capacities organizes content around typed objects — a Person, a Book, a Meeting, a Daily Note — each with its own structured properties.
Objects can be linked together and explored through an interactive graph view, giving users a way to navigate a knowledge base by relationship instead of a folder tree, which the company positions as a middle ground between the flexibility of networked notes and the structure of a database.
Core features include Daily Notes for quick capture, custom object types and templates, properties and relations for structuring data, and tagging and collections for grouping related objects. An AI assistant, available on paid plans, can answer questions about a user's own notes, summarize content, and help draft new entries.
The app is offline-first, syncing across devices once a connection is available, and supports export to Markdown, HTML, or JSON to avoid vendor lock-in. Capacities runs as native apps on Mac, Windows, and Linux, as a web app, and, since July 2024, as native iOS and Android apps with tablet-optimized versions.
Capacities offers a Free plan with no cap on notes or objects and 5GB of media storage, making it usable as a primary note app without paying. Pro costs $9.99/month billed annually ($11.99 monthly) and adds unlimited storage, the AI assistant, saved queries, and calendar integration.
A Believer plan, at $12.49/month annually ($14.99 monthly), includes the same features as Pro but is framed by the company as a way for users to directly support ongoing development.
