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 multi-platform AI chat client that connects to any model you choose
Configure the AI providers or API keys you already use, and switch between them inside the client instead of committing to a single bundled service.
Native apps for Windows, macOS, Linux, iOS and Android keep your conversations and settings aligned across devices.
Drag in PDF, Word, Excel, PowerPoint, code and image files and let the model summarise, extract or analyse the content directly.
Edit the same image across multiple turns, automatically carrying over the previous version and merging several images while keeping subjects consistent.
