Frequently Asked Questions

Is Capacities free to use?

Yes. The core product of Capacities is free forever — you get unlimited notes, objects, and cross-device sync with no time limit and no credit card required. Advanced features like the AI assistant, smart queries, and calendar integrations are available on paid plans.

What are the paid plans and what do they unlock?

Capacities offers two paid tiers: Pro (which adds AI assistance, queries, and calendar features) and Believer (a supporter tier for those who want to back the team's mission). Both are subscription-based. Check capacities.io/pricing for current plan details.

What makes Capacities different from other note-taking apps?

Instead of storing everything as generic files in folders, Capacities uses an object model — each 'Person', 'Book', 'Project', or 'Idea' is a typed entity with its own properties and links. This makes your knowledge base feel like a living network rather than a filing cabinet.

Does Capacities support team or collaborative workspaces?

Capacities is designed primarily as a personal knowledge management tool for individuals. It does not currently offer real-time collaborative workspaces in the way dedicated team tools do, making it best suited for solo knowledge work.

Can I get my data out of Capacities if I decide to leave?

Yes. Capacities supports full data export in standard formats so you are never locked in. The team emphasises data portability as a core principle, and all your content remains yours.
