OpenAI's Chromium-based web browser with ChatGPT woven through it: a sidebar that can summarize, compare, and answer questions about any page, optional browser memories that carry context across sessions, and an agent mode that navigates sites and completes multi-step tasks on your behalf. It launched on macOS in October 2025, with Windows, iOS, and Android versions announced. Free with any ChatGPT account; agent mode requires a paid plan.
