Multi-LLM browser extension

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 answers in one workflow.

Install guide Try web compare

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)
