Cuey

Cuey is a Chrome extension that fundamentally changes how you interact with artificial intelligence by ensuring you never have to trust a single model's confident-sounding answer again. In an era where AI models from ChatGPT to Claude to Gemini are used for critical research, advice, and judgment-heavy tasks, relying on one perspective is a gamble. Cuey acts as your AI referee, running your prompts against multiple models behind the scenes and surfacing a stronger, more reliable answer when one is available. This product is designed for professionals, researchers, students, and anyone who demands accuracy and depth from their AI tools. Beyond just comparison, Cuey solves the frustrating problem of siloed memory. Your context, preferences, and history are trapped inside each AI tool, forcing you to start from zero every time you switch. Cuey makes your memory portable, automatically carrying your context across ChatGPT, Claude, Gemini, Grok, Mistral, DeepSeek, and over 30 more models. This means you can compare, switch, and iterate freely without losing progress. Cuey is built with privacy by architecture, not by policy. All sensitive data is encrypted on your device, never stored on servers, and there is zero prompt logging, training on your data, or browsing tracking. It is a battle-tested tool for the modern AI user who refuses to settle for one opinion.

Multi-Model Comparison Engine

Cuey does not just let you manually copy and paste prompts between tabs. It actively checks other models in the background as you work with ChatGPT, Claude, or Gemini. When your task involves research, advice, or judgment-heavy decisions, Cuey automatically queries a network of over 30 supported models, including Grok, Mistral, and DeepSeek. It then surfaces a stronger, more reliable answer when one is likely available. This head-to-head comparison ensures you are not fooled by a single confident-sounding but potentially incorrect response, giving you multiple perspectives from one single prompt.

Portable Memory Across All Models

Your context, preferences, and history have been held hostage by individual AI tools for too long. Cuey breaks these silos by making your memory portable. Once installed, your conversation history, personal context, and preferences follow you automatically across ChatGPT, Claude, Gemini, and over 30 other models. This means you can switch from one model to another mid-task without starting over. Every model you use will already know you, your project details, and your preferred style, saving you hours of repetitive context-setting.

Privacy-First Architecture

Cuey is designed with a privacy-first architecture that puts you in complete control. Unlike other tools that log your prompts or use your data for training, Cuey encrypts all sensitive data directly on your device. It never stores your prompts, your history, or your browsing activity on its servers. There is no prompt logging, no training on your data, and no browsing tracking. This is privacy by architecture, not by policy, ensuring that your most sensitive research and personal information stays under your control at all times.

Seamless Workflow Integration

Cuey works where you already work, integrating directly into the AI tools you already trust. It functions as a lightweight Chrome extension that sits alongside ChatGPT, Claude, and Gemini. You do not need to change your workflow or learn a new interface to get the benefits of multi-model comparison and portable memory. As the model landscape changes and new AI tools emerge, your workflow does not have to. Cuey adapts, ensuring you always have access to the best possible answers without tab hopping or manual cross-referencing.

Academic Research and Fact-Checking

For students, researchers, and academics, getting a single answer from one AI model can be dangerous. Cuey allows you to run your research questions against multiple models simultaneously, cross-referencing facts, citations, and explanations. When one model confidently states a false premise, another model might catch the error. This use case is critical for literature reviews, data analysis, and verifying complex scientific concepts. Cuey ensures your research is built on a foundation of multiple verified perspectives, not just one confident voice.

Business Decision-Making and Strategy

Business leaders and strategists cannot afford to make decisions based on a single AI's output. Cuey enables you to get multiple perspectives on market analysis, competitive intelligence, and strategic planning. By comparing outputs from models like ChatGPT, Claude, and Gemini, you can identify biases, gaps, and alternative viewpoints. This head-to-head comparison leads to more robust business strategies and reduces the risk of costly errors. Your memory is also portable, so your company's context and previous analyses follow you across all models.

Content Creation and Copywriting

Content creators, marketers, and copywriters often need to generate multiple variations of headlines, taglines, or campaign copy. Cuey lets you prompt once and receive multiple creative outputs from different models, each with its own stylistic strengths. You can then compare, refine, and combine the best elements from each. Your portable memory ensures that brand guidelines, tone preferences, and project history are automatically applied across all models, making the creative process faster and more consistent.

Technical Troubleshooting and Code Review

Developers and IT professionals frequently use AI for debugging, code review, and technical problem-solving. A single model might miss a subtle bug or suggest an inefficient solution. Cuey runs your technical queries against multiple models, surfacing the strongest, most accurate solution. This is invaluable for complex code reviews, architecture decisions, and learning new technologies. Your portable memory also retains your codebase context, project structure, and previous fixes, allowing you to switch models freely without re-explaining your entire setup.

How does Cuey compare answers from different models?

Cuey does not simply display answers side by side. It actively analyzes the outputs from multiple models in the background, comparing them for consistency, accuracy, and depth. When one model's answer significantly differs or appears more reliable, Cuey surfaces that as a stronger possible answer. This automated comparison saves you from manually reading through multiple responses and helps you identify the most trustworthy perspective quickly.

Does Cuey use my prompts for training or store them on servers?

No. Cuey is built on a privacy-first architecture. Your prompts are never used for training any AI model, and they are not stored on Cuey's servers. All sensitive data is encrypted on your own device. There is no prompt logging, no browsing tracking, and no collection of your data for any purpose beyond providing you with real-time comparisons. Your privacy is guaranteed by the architecture, not just a policy document.

Can I use Cuey with models I already have accounts for?

Yes. Cuey works alongside the AI tools you already use, including ChatGPT, Claude, Gemini, Grok, Mistral, DeepSeek, and over 30 more. It integrates as a Chrome extension, so you do not need to create new accounts or learn new interfaces. Cuey simply adds a layer of comparison and memory portability on top of your existing workflows. You can see the full list of supported models on the Cuey website.

How does portable memory work across different AI models?

When you use Cuey, your conversation history, context, and preferences are stored securely and encrypted on your device. When you switch from one model to another, Cuey automatically injects that context into the new model's session. This means the new model already knows your project details, your name, your preferred tone, and any previous instructions. You never have to start from zero or re-explain your situation, saving significant time and reducing frustration.
