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.

What our users are saying about Kosmik.

George

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

Benjamin

Independant Writer.

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.

Pavan

Medical Doctor.

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.

Tim

Toy designer, inventor.

It's absolutely awesome. 

I have dreamed of an app like for years so thank you! I use the browser to log into my task app to have an easy access to all my projects.  Really awesome work. 

Alex

UX researcher.

Just downloaded on windows! 

I have been switching between 

browsers for almost a decade 

now, and I've never seen 

something like this! I think this is a fabulous idea.

Now I finally have a place to store my files, articles and notes. I can easily check references with the browser and add relevant items. The search feature easily saved me 2 hours of work this week!
