Capacities
Capacities reimagines note-taking by organizing everything around objects (people, meetings, books) instead of folders, creating a knowledge graph that actually feels natural once you adjust to it. It's genuinely innovative with solid AI features, but the learning curve and occasional sluggishness mean it's not for everyone.
Capacities shows genuine utility as an object-based knowledge management tool with a strong free tier, but no G2/Capterra reviews exist to confirm core task utility claims, integration depth is minimal (Zapier/Make are only planned), and reliability signals are thin due to sparse independent user reviews.
No SOC 2, HIPAA, or ISO certifications were found, no security page details surfaced, and privacy posture on AI training data use is ambiguous; the absence of G2 reviews further limits trust triangulation, capping confidence.
Adoption signals are vague ('thousands of thinkers'), no VC funding beyond a regional media lab investor, no major marketplace presence, and near-zero presence on review aggregators indicate an early-stage niche product with limited ecosystem traction.
The July 2026 API 2.0 launch with OAuth 2.1, CRUD operations, TypeScript SDK, and MCP support demonstrates meaningful developer investment, though Python SDK and Zapier/Make integrations remain unshipped, and the beta API deprecation creates migration friction.
Most note-taking apps are just digital filing cabinets—you stuff things in folders and hope you remember where you put them. Capacities takes a genuinely different approach: instead of organizing by location, it organizes around objects like people, projects, and ideas, creating a web of connections that mirrors how you actually think. After three months of daily use, I'm convinced this is either the future of knowledge management or an overly clever solution to a problem most people don't have.
