OpenAI has launched a Chrome extension for its Codex platform, enhancing its capabilities for users. The extension includes features for testing web applications, collecting context from open tabs, and utilizing Chrome DevTools alongside other tasks.
This plugin aims to broaden Codex’s appeal to casual users and professionals beyond developers, recognizing that many computing tasks occur within web browsers.
Codex can now take on more of your browser dev work.

OpenAI originally introduced Codex as a macOS application in February and subsequently added features in April. The company plans to eventually release a unified application that integrates Codex with the ChatGPT chatbot and its web browser, Atlas.
The Codex Chrome extension is compatible with both Windows and Mac operating systems.
