One privacy-first AI client for GPT, Claude, Gemini and more
Switch between GPT, Claude, Gemini, Grok, DeepSeek and many other providers in one client by plugging in your own API credentials.
Upload PDFs, Office documents, images and code, then ask the app to summarise, explain or extract what you need.
Store documents locally so Chatbox can recall and answer from your own materials while your data stays on your machine.
Pull current results from the web and display answers with Markdown, Mermaid diagrams, LaTeX formulas and code previews.

A lightweight Chrome extension for one-click ChatGPT access
Open a ChatGPT prompt window straight from the Chrome toolbar instead of switching tabs and loading the full ChatGPT site.
The extension has no sign-in flow and is designed to stay reachable even when ChatGPT's own servers are busy.
Exposes additional model parameters beyond the default ChatGPT interface so you can experiment with how responses are produced.
Your variables and settings are stored in your own browser rather than on a remote account, and the developer declares no data collection.
