ChatGPTBox is a browser extension that integrates conversational AI into the pages you already read. Instead of copying text into a separate chat window, you can open a floating dialog on any site with a keyboard shortcut and ask questions with the page content as context. A right-click menu lets you summarize an article, translate a paragraph, split text into sections, or explain a block of code in place.
Beyond the inline panel, the extension ships a standalone conversation page and adapts to a long list of frequently used websites and search engines. You can connect it to several API providers — including the ChatGPT web session used by free and Plus accounts, plus GPT-3.5, GPT-4, and other compatible endpoints — and set a custom API address if you run your own gateway. Static cards support branching, multi-thread conversations so you can compare answers side by side.
The extension renders code with syntax highlighting and complex mathematical formulas cleanly, supports language preferences, and lets you save or partially copy your full chat history. Every site adaptation and selection tool can be toggled on or off, and the open-source codebase is designed to be easy to extend. It is maintained by an individual developer and offered under a free, donation-supported model.
