The Browser Company has released its AI-powered browser, Dia, to all macOS users without requiring an invitation. The software integrates a chatbot directly into the browsing experience after the company shifted focus from its previous product, Arc.
Following a private beta period that began in June, the browser, first revealed at the end of the previous year, is now publicly accessible. Dia requires specific hardware and software, running only on Mac computers equipped with an M1 chip or a later model and requiring macOS 14 or a more recent version. Its core feature is a chatbot embedded within every open tab. This tool enables users to conduct web searches, compare different websites, and ask questions specific to the content on the page. The AI can also perform inline copy editing and summarize text directly, eliminating the need for copying and pasting. The chatbot is capable of providing practical advice, such as discouraging a user from making an expensive purchase if prompted.
Earlier in 2025, The Browser Company pivoted its entire strategy to concentrate on Dia, moving away from its former browser, Arc. Chief Executive Officer Josh Miller stated that Arc “lacked cohesion in its features and value” and was ultimately “too different” to achieve wide-scale adoption. The company has confirmed that it will continue to provide security updates for existing Arc users.
The Browser Company has also been acquired by Atlassian in a transaction valued at approximately $610 million. This deal is expected to be finalized by the end of 2025. According to the announcement, the acquisition will permit The Browser Company to operate as an independent entity while accelerating the rollout of Dia. A version for Windows has not been confirmed, though a future release is considered possible given Arc’s previous availability on that platform.
