ChatGPT Atlas
OpenAI's own web browser, with ChatGPT built in and an agent mode that clicked through sites for you.

Why 3: its agent mode opened tabs and completed tasks such as hotel bookings, but asked for confirmation before sending messages or making payments, so it never finished those steps alone.
What it does. Atlas put ChatGPT beside every page and offered an agent mode that could open tabs, click through sites and complete tasks such as hotel bookings, asking for confirmation before sending messages or making payments. OpenAI announced its retirement on 9 July 2026, alongside ChatGPT Work, and scheduled the shutdown for 9 August 2026.
Where it falls short. It never left the Mac. OpenAI said its agent mode "expands the security threat surface" and wrote that prompt injection "is unlikely to ever be fully 'solved'".
