What is Cuey?

Cuey is a Chrome extension that sits beside your favorite AI tools so you can compare answers across multiple models without switching tabs. It makes your context, preferences, and chat history portable across ChatGPT, Claude, Gemini, Grok, Mistral, and 30+ other models. By cross-checking other models behind the scenes, Cuey helps reduce reliance on a single confident-sounding answer and lowers hallucination risk.

How to use Cuey?

1. Add Cuey to Chrome and pin the extension to your toolbar. 2. Use ChatGPT, Claude, or Gemini as you normally do — Cuey runs quietly alongside and speaks up when it finds a meaningfully different answer from another model. 3. Enter a prompt or pick one of Cuey's suggested prompts to compare answers across models in real time. 4. Install the extension to unlock more free comparisons and upgrade for higher daily usage.
