“Open AI browser” means ChatGPT Atlas
When you search open ai browser or open ai 浏览器, top results are OpenAI’s ChatGPT Atlas — a Chromium browser with ChatGPT built into every tab.
Atlas focuses on sidebar assistance, browser memory, and agent tasks inside ChatGPT. It launched macOS-first with Windows rolling out by region.
If you want an OpenAI-style AI browser you can run today on Windows — with stronger Agent workflows and regional models — Tabbit is built for that gap.
