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.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
