The New York-based startup's Dia browser, which was launched earlier this year, faces tough competition from the likes of Nvidia-backed Perplexity's Comet and Brave's Leo. Atlassian plans to make Dia its go‑to browser for work, designed to pull together tasks and tools from across the web and add context in enterprise environments.
