AI browser by The Browser Company (Atlassian)

Dia review

Published · Updated

Dia is an AI browser for Mac and Windows from The Browser Company, which Atlassian bought in 2025. You chat with your open tabs, use Skills for common tasks, and get a Morning Brief. Atlassian has been repositioning it toward work.

Rank 3 of 4 ai browsers

5.9/10

Is Dia worth it?

It depends on what you need it to do. Dia is an AI browser. Price as of November 2026: from $10/mo. It's worth it if you want help reading and researching in your browser, not an agent that acts. The main catch: doesn't complete errands on websites. Perplexity Comet is the better choice if you want an AI browser that's free on Mac, Windows, iPhone and Android and does great research.

Our verdict

Dia is a pleasant AI browser for reading and research, with good personal memory. As an agent it does the least here: it doesn't click through sites to finish errands, its free plan has no AI, and its focus is shifting to business use.

Choose Dia if you want help reading and researching in your browser, not an agent that acts.
