The note-taking struggle
Most knowledge workers have tried 5-10+ apps before finding the right one. Here's how the cycle usually goes.
Notes everywhere. Ideas nowhere.
You've got stuff in Notion, Apple Notes, random docs, bookmarks... and you can never find what you need when you need it.
You've tried everything.
One app felt overwhelming. Another needed endless plugins. The next was too complex. You're starting to wonder if the problem is you.
Organizing has become the work.
You spend more time building systems than actually thinking. The tool that was supposed to help has become another job.
It's not you. It's your tools.
They were designed for computers, not humans. Files and folders made sense in 1984. Your brain doesn't work that way. Neither should your notes.
What if your notes worked like your mind ?
Your brain doesn't think in folders. It thinks in objects —people, books, ideas, projects. And it connects them naturally.
In Capacities, everything you care about becomes an object. A person. A book you're reading. A project you're working on. An idea you want to explore.
Objects have structure. They have properties. And they connect to each other creating a living network of your thoughts.
No more deciding which folder something belongs in. No more losing ideas in nested hierarchies. Just think, capture, and let the connections emerge.
"When I realised everything was an object—and I could link anything to anything—it clicked."
Files & Folders
Messy, deep, lost
Objects & Connections
Clear, connected, alive
What changes when your tools finally work
Capacities transforms how you capture, connect, and think about your knowledge.
Think in things, not files
Create a person, a book, a project—whatever matters to you. Each with its own structure. Each connected to everything else.
"The whole idea of everything being an object works for me."
Ideas find each other
Link anything to anything. Click on a person and see every note, meeting, and idea connected to them. Backlinks surface connections you didn't know existed.
"It felt magical the first time a connection surfaced that I hadn't made consciously."
Just start writing
Your daily note is your inbox. No pressure to organize. Just capture. Structure emerges naturally over time.
"The daily notes became a ritual—and then I saw how they stitched together all my scattered thoughts."
Power without endless customization
No configuration. No markdown syntax to memorize. No plugin rabbit holes. Just open it and think.
"I love that I can just open Cap and it works."
