Our Review
4.5 / 5.0
Cmd J – ChatGPT for Chrome stands out as an exceptionally practical and efficient AI tool for anyone who frequently interacts with text online. Its core strength lies in its unparalleled accessibility; the simple keyboard shortcut eliminates the need to switch tabs or applications to leverage ChatGPT’s power. The ability to perform actions like summarizing or rewriting text directly on the page you’re viewing is a significant boost to productivity for writers, researchers, and students alike. While the extension itself is free, it’s important for users to note that utilizing the more advanced GPT-4 model requires an OpenAI API key, which incurs separate costs directly from OpenAI. Despite this, the extension’s robust functionality, high user ratings, and large user base underscore its reliability and effectiveness as a go-to AI assistant for daily browsing tasks.
