"After 24 hours of using Capacities I can confidently say I'm falling in love."
Your best thinking keeps slipping away
You read, research, meet, and think all day. But when you need that one insight, that one connection? Gone.
Notes everywhere. Ideas nowhere.
Meeting notes, article highlights, project ideas, fleeting thoughts. They're scattered across apps, docs, and messages. When you need something, you end up searching five places.
Your knowledge doesn't connect.
You read something last month that's relevant to today's project. You know it exists. But your tools treat every note as an island, so the connection stays in your head or gets lost.
Organizing has become the work.
Where does this go? What folder? What tag? You spend more time filing than thinking. The tool that was supposed to help has become overhead.
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 things —people, books, ideas, projects. And it connects them naturally. We call these objects.
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. In Capacities, we call these objects. 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. Backlinks show you every connection at a glance. And unlinked mentions go even further: Capacities scans your notes and surfaces places you wrote about something but never linked. Connections you already made, found automatically.
"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 and link as you go.
"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 Capacities and start writing.
"I love that I can just open Cap and it works."

Three steps to a clearer mind
No complex setup. Just open the app and start getting your thoughts down.
Start with today
Open your daily note. Write whatever's on your mind. No structure required—just capture.
Turn thoughts into objects
A meeting becomes a Meeting object. A book becomes a Book object. And for your next project, simply create a Project object. Create the object types you need as you go.
Watch connections grow
Over time, links between your objects reveal patterns. Click on any object and see everything connected to it.
You'll be surprised how much clarity comes from simply writing things down without getting distracted by constantly having to organize your notes. Start with a few daily notes, and add the object types you really need. Your system will grow with you over time.
