What is a multi-LLM browser extension?
A multi-LLM browser extension lets you run the same prompt across several large language models from your browser. Qorpus does that as a compare-first AI aggregator using your existing AI logins.
Multi-LLM Browser Extension: The AI Aggregator
Qorpus is the compare-first browser extension for people who already use multiple frontier AIs. Install it, sign into the services you already pay for, and compare AI models side by side in one workflow.
Built for comparison, not another chatbot wrapper
Many “multi AI” tools wrap APIs or cram chats into one pane. Qorpus is different: it runs against your existing desktop browser sessions and focuses on judgment — what the models agree on, where they conflict, and which unique details matter.
- Works with ChatGPT, Gemini, Claude, Perplexity, and Grok
- No API keys required for the core compare flow
- Chrome / Chromium browsers (Brave and compatible browsers supported)
An AI aggregator built for comparison
Most AI aggregators route prompts through their own APIs and charge a second subscription. Qorpus is an AI aggregator that stays in your browser: it uses the ChatGPT, Gemini, Claude, Perplexity, and Grok accounts you already have, then shows every answer side by side so you can judge, not just collect chat tabs.
Multi AI chat across ChatGPT, Gemini, Claude, Perplexity and Grok
Multi AI chat in Qorpus means one prompt, every major model, one view. Type once and run multi LLM comparison across ChatGPT, Gemini, Claude, Perplexity and Grok without copy-paste. That is the multi AI model workflow the extension is built for — comparison first, not another single-pane chatbot.
