Plus, a built-in prompt library helps you stop reinventing the wheel every time you sit down to work.
🔀 COMPARE MULTIPLE AI MODELS AT ONCE

- Works directly on ChatGPT, Claude, Gemini and others, no separate app to open
- Supports: ChatGPT (GPT-4o, GPT-5), Claude (Sonnet, Opus), Google Gemini, Grok, DeepSeek…and all other major models.
Why it matters: Different models have different strengths. GPT-5 may excel at reasoning; Claude may write cleaner prose; Gemini has better web access. Cuey lets you see the difference in real time, without copy-pasting, tab-switching, or guesswork.

- Very slick. Integrates right into my workflow.
- Pizza Shiit
- Cuey is the “second opinion” layer AI was missing. Fast, simple, and incredibly useful for comparing model outputs without the tab chaos.
- Adam Kazwell
- It's so tempting to take AI's confident-sounding answers at face value, but Cuey is the "wait, are you sure?" layer I didn't know I was missing. Effortless second opinions from every major model without juggling tabs. 🥰
- Prateek Gupta
- I have been using Cuey for over 2 weeks now - solid concept. Being able to compare responses from multiple AI models side by side is genuinely useful and saves time. Helps catch bad outputs quickly and improves confidence in answers. UI is clean and easy to use.

- Love being able to compare multiple models! Way to go team
- Sarah Wakeman
- It's so cool being able to see the answers from multiple AI models in one place, and the analysis is super helpful as it tells you how and where the answers differ. I really love that it saves my prompts across models too as I work across GPT / Claude and Gemini all day in any case.
- Charles Lu
- This plugin is a must have if you use AI chatbots regularly. It runs your prompts against multiple models in the background and lets you know when there's a better answer out there. No extra effort on your part. Plus the cloud sync for chat history is something I didn't know I needed until I had it. Super handy.
