Capacities — Technical Overview
Capacities is a freemium, cloud-hosted knowledge management tool built around an object-based knowledge graph. Rather than organizing information in flat documents or folders, every piece of content (notes, tasks, media, people, etc.) is a typed object that can be linked bidirectionally to any other object — enabling a flexible, schema-light graph structure with no manual configuration required.
Key technical characteristics:
- Architecture: Cloud-hosted SaaS; not self-hostable. Servers are EU-based and GDPR-compliant.
- API: A public REST API is available on the Pro plan and above, enabling programmatic read/write access to your knowledge graph.
- Integrations: Native connectors for WhatsApp, Telegram, Twitter, Readwise, and Kindle — enabling capture from external sources directly into the graph.
- Data portability: Full data export is supported; no vendor lock-in.
- Sync: Real-time sync across mobile and desktop clients.
- AI: An AI assistant is bundled into the Pro plan. An optional Plus AI Power-Up add-on ($8.33/month billed annually) is available for extended AI capabilities.
- Pricing tiers: Free (Basic, forever) → Pro ($9.99/month) → Believer ($12.49/month, beta feature access).
- Funding model: User-funded with no VC backing; headquartered in Germany.
