What it is
ChatGPTBox is a browser extension that lets you call up an AI chat window on almost any web page with a keyboard shortcut. It can summarize pages, work on selected text (such as translating or explaining code), and appear beside search results or sites like GitHub and YouTube. It can connect to several AI services, including custom or self-hosted APIs.
- Press Ctrl+B on a page to ask questions about its content
- Right-click or use Alt+B to summarize a page
- Open an independent conversation page with Ctrl+Shift+H
- Use selection tools to translate, polish, or explain highlighted text
Great for
- People who want an AI chat panel available while browsing
- Readers who often summarize articles or videos
- Users who want to connect their own API endpoint in Custom Model mode
- Developers who want to use AI help on code pages such as GitHub
Not ideal for
- People who want a fully offline tool, since it sends prompts to a configured AI service when an AI feature is used
- Users who need guaranteed free access, because the README mentions a free Web API option but does not explain its limits
- Anyone needing a standalone desktop chat app rather than a browser add-on

Get the most out of it
- Use Custom Model mode to connect services such as Ollama or OpenRouter, as the README describes
- Pair with LiteLLM or one-api to convert other LLM APIs into OpenAI format, per the README
- Turn off site adaptations and selection tools you do not need, to reduce clutter
- Use the Independent Conversation Page (Ctrl+Shift+H) for longer chats
Downloads
Strengths
- Works across Chrome, Edge, Firefox, and Safari, per the README install links
- Many built-in integrations with sites and search engines, and features can be switched off
- The README states it does not transmit prompts or page content unless an AI feature is triggered, and points to code search for verifying network calls
Trade-offs
- Depends on an external AI service, so results and privacy depend on the service you configure
- The README is truncated and does not fully document setup for every AI provider
- Some listed features depend on which API you choose, such as Web API for free users
