The Browser Company’s Dia is now available on Mac, no invite needed

The Browser Company’s AI-powered browser is now available to download for all macOS users. Dia started rolling out to private beta testers in June, following its initial reveal at the end of last year, but if you’re a Mac user you can download it here if you want to try it. Note that you need a Mac with an M1 chip or later running macOS 14 or later.

AI is being baked into a lot of web browsers right now, but with Dia it’s at the heart of everything you do. It allows you to interact with The Browser Company’s chatbot within every tab you have open, where it’s able to search the web, compare websites and answer questions about the content displayed on the page you have open. It features an in-line copy editor too, and can summarise text without requiring you to copy-paste it into a separate field. It’ll also happily talk you out of an expensive purchase, if prompted.

The Browser Company previously worked on the popular Arc browser, but shifted its focus entirely to Dia back in May, after CEO Josh Miller said the former “lacked cohesion, in both its core features and value.” Miller said Arc was “too different” for widespread adoption, but committed to providing future security updates for the people who were on board (many of whom were effusive in their praise).

The Browser Company was recently acquired by Atlassian in a deal worth around $610 million, which should be finalized by the end of 2025. As part of the agreement, the former was allowed to continue operating independently while it worked on Dia, and wrote in a blog post published at the time that the acquisition would help it roll out its new AI browser more aggressively. At the time of writing, there’s no word on plans for a Windows launch. But given Arc eventually made its way to Windows, chances are it’ll happen sooner or later.
