A browser you actually shape.
Most browsers decide how they look and how they work, and you live with it. Cule flips that. You describe what you want, and your browser becomes it.
Why we built it
The browser is the app most of us live in all day, yet it is the one we are least allowed to change. Settings menus someone else designed. Features you never asked for. No real way to make it yours. We thought that was backwards. The thing you use most should bend to how you work, not the other way around.
How it works
You connect a coding agent, Claude Code, Codex, or whatever you run, to the Cule workspace folder. Then you prompt the changes you want: a calmer new tab, a split view for research, a layout built around one specific task. Your agent builds it live, in the browser you are looking at. When you like a setup, you save it as a template.
Do not write code? That is fine. Cule ships with templates, and you can load anyone else's.
Every template is a whole browser
A template can change everything: the chrome, the tabs, how pages behave. Switching between them feels like switching between apps. Keep your own, load someone else's, or share what you made.
Because templates can run code, only load ones from people you trust, the same way you would treat any script.
Built in the open, still in alpha
Cule is early and built by one person. Some things are rough and some are missing. We would rather put it in your hands now, talk to the people who get it, and build the rest together than polish in private for a year. If that sounds like you, come say hi.
