chatGPTBox

ChatGPT Box is a browser extension that adds a ChatGPT chat panel to any web page you visit. It works in Chrome, Edge, Firefox, and Safari, and also supports Android browsers. Once installed, you can open a chat window on any page with a keyboard shortcut, ask questions about what you are reading, or trigger various text tools by selecting text on the page.

The extension integrates directly with popular sites. On search engines, it shows AI answers alongside your search results. On YouTube, it can summarize video content. On Reddit, GitHub, GitLab, StackOverflow, and other sites, it adds specific tools suited to that kind of content. You can also highlight any text on any page and use a floating toolbar to translate it, rewrite it, analyze its tone, break it into paragraphs, or ask the AI to explain it.

The extension connects to multiple AI backends. You can use the free ChatGPT web interface without an API key, or connect directly to the OpenAI API with GPT-3.5 or GPT-4. It also supports Claude, Bing, and self-hosted models through tools like Ollama or any service that follows the OpenAI API format. A custom API address field lets you point it at your own server or a proxy.

Conversations can branch in multiple directions, letting you explore different follow-up questions from the same point in a chat. Chat records can be saved or copied. The extension renders code with syntax highlighting and handles mathematical formulas correctly.

The project does not collect user data. Requests to AI services only happen when you explicitly click a button or trigger a tool, not automatically as you browse. Individual site integrations and selection tools can each be turned on or off in the settings, so you can keep only the features you actually want.
