Side-by-side answer comparison
Run one prompt across selected AI models and review their responses together in Cuey's browser sidebar.
Cuey
Cuey is a Chrome extension that compares answers from multiple AI models side by side, spots omissions and disagreements, and transfers context without API keys or an account.
AI answer comparison inside the browser
Cuey is a Chrome extension for comparing generative-AI answers without switching between model tabs. It runs alongside supported AI services, sends a prompt to selected models, and displays the resulting answers in a sidebar for side-by-side review.
The comparison workflow is designed to help users identify agreement, disagreement, and missing information before relying on an AI response. Cuey supports ChatGPT, Claude, Gemini, Grok, DeepSeek, and other models, and also offers context-transfer features for users who want to carry conversation history and preferences between supported services.
Features
Cross-model checking
Compare an answer against more than 30 models and inspect where responses agree, diverge, or omit information.
In-context browser workflow
Use Cuey inside supported AI websites rather than moving between separate model tabs or applications.
Context and memory transfer
Import chat history and memories from ChatGPT, Claude, and Gemini so context, preferences, and prior conversations can carry across supported models.
Manual model routing
Choose models manually for a prompt, with model options organized into default/basic, advanced, and ultra capability tiers.
Prompt library
Use a prompt library containing copy-ready templates across categories such as accounting and financial analysis.
Use cases
Reviewing business writing
Run a draft through several models and compare structure, tone, and omissions before using it in client or internal communication.
Checking research and analysis
Use multiple model responses to surface disagreements, assumptions, or missing context in research and analytical work.
Working from reusable prompts
Select a prompt template from the library, route it to chosen models, and compare outputs for tasks such as financial summaries, forecasts, or risk assessments.
Continuing an existing AI workflow
Carry relevant history and preferences from supported AI services when changing models, reducing the need to restate an ongoing task.
Multilingual drafting
Use multilingual support and compare responses when drafting or reviewing content for audiences in different languages.
