When you rely on a single AI model for research, coding advice, or decision-heavy tasks, you are betting that one confident-sounding answer is the right one. Cuey is a Chrome extension that lets you cross-check answers across ChatGPT, Claude, Gemini, Grok, Mistral, and over 30 other models from a sidebar—without switching tabs or copying prompts.

What Cuey Does
Cuey sits in your browser as a sidebar. When you send a prompt to ChatGPT, Claude, or any supported model, Cuey can simultaneously query other models in the background and show you their responses side by side. No manual copy-pasting, no opening multiple tabs.
The key idea: a "second opinion" on every AI response. For judgment-heavy tasks—research summaries, legal interpretations, debugging suggestions, content reviews—seeing how multiple models answer the same question can reveal blind spots, hallucinations, or alternative approaches that a single model would miss.
Key Features
Side-by-Side Comparison
Send one prompt and see responses from multiple AI services rendered in a clean comparison view. Models are clearly labeled so you can quickly scan which answer you trust most.
Portable Memory
One of Cuey's more distinctive features: your context, preferences, and history follow you across models. If you switch from Claude to ChatGPT, you do not start from zero. Cuey carries your conversation context automatically.
Privacy-First Architecture
Cuey encrypts sensitive data on your device and states it does not store prompts on its servers, does not use your data for training, and does not track browsing. Prompt data flows directly between your browser and the AI provider APIs.
30+ Model Support
The supported model list includes ChatGPT, Claude, Gemini, Grok, Mistral, DeepSeek, and many others. As new models launch, Cuey adds support without requiring you to change your workflow.
Who Should Use Cuey
- Researchers and analysts who need to verify AI-generated facts across multiple sources
- Developers comparing code suggestions from different coding assistants
- Content teams checking for hallucinated claims before publishing
- Decision makers who want multiple AI perspectives on strategic questions
Pricing
Cuey offers a free plan with access to all supported models but limited daily comparisons. Paid plans increase comparison limits across daily, weekly, and monthly caps. Specific pricing is available on their website.
Strengths
- Works inside your existing AI workflow, no tab switching
- Portable memory across models is genuinely useful
- Privacy-first approach with on-device encryption
- 30+ models supported from a single interface
- Free tier lets you evaluate before committing
Limitations
- Chrome only (no Firefox or Safari support)

- Requires your own API keys or subscriptions to the underlying AI services
- Comparison quality depends on which models you have access to
Our Verdict
Cuey addresses a real gap: the risk of trusting a single AI model for important decisions. The browser-extension approach means zero friction—you keep using ChatGPT or Claude as usual, and Cuey adds the safety net of a multi-model check. The portable memory feature is a bonus that becomes hard to give up once you have tried it. If you work with AI daily and want to reduce hallucination risk, Cuey is worth installing.
