The Browser Company’s Dia is now available on Mac, no invite needed (www.engadget.com)

The Browser Company has opened Dia, its AI-first browser, to all macOS users — no invite required. After a private beta that began in June and an initial reveal late last year, Dia can now be downloaded on Macs with an M1 chip or later running macOS 14+. Unlike browsers that bolt on AI features, Dia embeds a chatbot into every tab so it can read the page you’re on, search the web, compare sites, summarize text in-line (no copy-paste), offer copy-editing, and even advise against pricey purchases when prompted. This matters because Dia represents a tighter integration of large-language-model capabilities into core browsing workflows, shifting the browser from a passive viewer to an active assistant that contextualizes and manipulates on-page content. The Browser Company pivoted away from its earlier Arc product to focus wholly on Dia, and its recent $610M acquisition by Atlassian — structured to let the team operate independently — should accelerate rollout and product development. There’s no Windows version yet, but given Arc’s later cross-platform move, broader availability seems likely. For developers and researchers, Dia’s approach highlights new UX patterns and privacy/compute trade-offs as AI becomes fundamental to how people browse.
