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.
If you're drowning in disconnected notes and genuinely want a smarter way to build a personal knowledge system, Capacities is worth the adjustment period—the object model really does make connections visible that you'd otherwise miss. But if you need quick capture without thinking about structure, or you're shopping for team collaboration features, stick with Notion or skip this entirely.
