AI BriefingCodex Adds Browser Use to Support Website Implementation and Verification
Key point
A Browser Use plugin has been added to Codex, combining web app implementation and verification into a single flow.
Details
With the Browser Use plugin, you can now run a browser inside the Codex app to test web apps as if a real user were clicking through them.
After Codex builds the frontend code, it interacts with the web app while directly viewing the screen via vision, and also checks network and console logs together.
By combining Build and Verify into one during local development, it provides a more automated development flow.
At the same time, GPT-5.5 was added, and support began for Sheets / Slides / Docs / PDF generation options and OS-wide shortcut dictation.
