BraveGPT

BraveGPT is an open-source userscript that integrates ChatGPT responses directly into the Brave Search results page. Designed for desktop and mobile browsers, it works with a variety of userscript managers like Tampermonkey and ScriptCat, and is compatible with major browsers such as Chrome, Firefox, Edge, Safari, Opera, and Brave. BraveGPT features a Proxy API Mode which, when enabled, allows users to get GPT-4o answers without a ChatGPT account; otherwise, it retrieves responses by using the user's existing ChatGPT session.
