Dia Browser
The AI browser where you can chat with your tabs
Visit website →About
Dia is an AI web browser from The Browser Company, the team behind Arc. It puts an assistant next to the page that can read and reason over open tabs, so a user can ask questions across their tabs, summarise what they are reading, compare pages, and pull information together without copying it out.
It can also write in the user's own style, help plan and research, and assist with tasks like shopping, with privacy controls the user manages.
It is aimed at people who do a lot of reading and research in the browser and want the AI built into where that work already happens rather than in a separate chat window.

Why we picked it
Dia, from the team behind Arc, puts an assistant beside the page rather than in a separate search box — it reasons across your open tabs directly, so comparing or summarizing what you're reading doesn't require copying anything out.
