The company behind Arc is building a new AI web browser called Dia

According to the teaser, Dia has familiar AI-powered features like “write the next line,” — which fetches facts from the internet, as demonstrated by pulling in the original iPhone’s launch specs — “give me an idea,” and “summarize a tab.” It also understands the entire web browser window, allowing it to copy a list of Amazon links from open tabs and insert them into an email via written prompt directions.

“AI won’t exist as an app. Or a button,” a message on the Dia website reads. “We believe it’ll be an entirely new environment — built on top of a web browser.” It also directs visitors to a list of open job roles that The Browser Company is recruiting to fill.

Another feature in the video shows Dia “performing actions on your behalf” by typing commands into the address bar — such as asking it to find a specific document based on a description and then sending it to someone via your preferred email platform. A third, more ambitious prototype feature shows Dia automatically completing more complex tasks, such as adding a list of generic items like “a sleeping mask” and “jelly beans” to the user’s Amazon shopping cart or emailing individually tailored information like call times to a list of staff on a video recording session.

So, what does this mean for Arc? Miller has said the startup isn’t planning to kill its first browser. In this video, he notes concern from users that a second product would result in the Arc browser being discarded, however, and says, “In my bones, I feel like this is so obviously where the world’s going.”
