Dia Browser

Dia is a browser from the team that made Arc, rebuilt around an AI chat in the address bar. You can ask questions about the current tab or all open tabs, rewrite text and automate small tasks without leaving the page.

It leans on a simple idea: the browser already knows what you are reading, so the assistant should too. Custom skills let you save prompts you use often.

It is a Mac-first product and still maturing. If you live in your browser all day, it is a fresh take on how the web could feel.
