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.
Lifetime desktop AI client that runs on your own API key
Enter an API key from a supported AI provider and start chatting from a native desktop app on Windows, macOS, or Linux, with no monthly chatbot subscription.
A curated set of ready-made prompts for common tasks, plus tone and advanced output settings so you can tune responses without rewriting instructions every time.
Create reusable AI agents and switch between them for different workflows, alongside image generation from inside the same desktop client.
The vendor states chat data is never stored on its servers, keeping conversations on your own device.
