The best browser for
visual research and notetaking

The single platform to browse, capture, and organize your knowledge.

Where browsing meets thinking.

Most note-taking apps make you leave your browser. Kosmik turns your browser into a powerful research environment - capture visually, organize spatially, and navigate your knowledge like you're exploring a map, not a file system.

Product Manager at FAANG

I was never using mind-mapping or whiteboarding software before. But Kosmik is different, the in-app PDF reader and web browser makes it my one-stop-shop for research, note-taking and knowledge management

Why do I like Kosmik? It feels organic and eases my cognitive load by not making me use several apps where one is enough. I don't spend any time tinkering with it. As a result, I can, just start creating.

What I appreciate about Kosmik is how it emphasizes the most important part of learning: acquiring material in a non-linear fashion. I absolutely love the concept and how it flows.
