Capacities

Capacities is a knowledge management app that describes itself as a studio for your mind, designed for writers, researchers, developers, students, managers, and founders who think in concepts rather than file hierarchies.

Instead of storing notes as pages in folders, Capacities turns ideas, people, books, projects, and other entities into typed objects that link to one another, with automatic backlinking and discovery surfacing related content as your knowledge base grows.

A daily-note inbox lets you capture thoughts quickly without forcing organization up front, and custom object types let you model structures that match your own workflow.

The Pro tier adds AI capabilities along with advanced queries and calendar features, helping you search, summarize, and work across your objects more intelligently. Full data export is supported so users retain ownership, and EU hosting keeps it GDPR compliant.

Pros include a genuinely different and flexible object model that suits networked thinking, an ADHD-friendly low-friction capture flow, and strong data ownership guarantees.

Cons are that AI and the more powerful features require the paid Pro plan, and the object-based paradigm can feel unfamiliar to people used to traditional folders and documents.

It fits people building a long-term personal knowledge base or second brain who value structure and connections over rigid folders and want their notes to grow into a navigable web of ideas. Capacities offers a free plan plus paid Pro and Believer tiers.

Pricing changes often, so check the official site for current plans.
