Cuey

Cuey is a Chrome extension that lets you compare any AI answer against 30+ models without leaving the AI tool you already use. It sends your prompt to ChatGPT, Claude, Gemini, Grok, DeepSeek and other leading models, then displays their responses side by side in a clean sidebar so you can see what they agree on, what they disagree on, and what your original model missed. It is built for anyone who relies on AI for everyday work and wants a second opinion before acting on a single model's confident-sounding answer. It is free to install, and no account is required to start. AI models deliver wrong answers in exactly the same confident tone as correct ones, which makes it hard to tell when you should trust a response and when you should look closer. Different models also have different strengths: one may reason through a problem better, another may write stronger ad copy, and another may have real-time internet access. Because each tool lives in its own tab, checking a second or third model normally means copy-pasting the same prompt, repeating your context, and juggling multiple subscriptions. Cuey removes that friction by putting the comparison directly where the question was asked, so a second opinion is available at the moment you need it rather than after a manual round trip between browser tabs. The core capability is multi-model comparison. Cuey works directly inside your AI tool, so there is no separate app to learn and no new interface to adopt. You send one prompt to multiple models at once, and Cuey runs it across your selected models before laying the responses out side by side in its sidebar. The free plan includes full side-by-side model comparison and works inside all seven major AI model providers covered by the extension, while cross-checking answers against more than 30 models is available with a daily free limit. Seeing the responses next to each other makes it possible to judge differences in reasoning, tone, and completeness at a glance instead of relying on memory of what another tab produced earlier. Cuey does more than display answers in parallel; it highlights the relationships between them. It shows where models agree, where they diverge, and why the difference matters, plus what your original model missed. Agreement is a signal that you can move forward with more confidence, while disagreement is a signal that the question deserves a closer look before you act. This is the mechanism that turns a wall of competing text into a usable judgment: instead of reading three or four answers and guessing which one to trust, you see the points of consensus and the points of conflict isolated in the sidebar. Memory portability is the second pillar of the product. Cuey lets your context follow you when you move between models, so you never start from zero again. You can import your chat history and memories from ChatGPT, Claude, and Gemini, then carry that context, along with your preferences and history, across supported models. Switching to a different model no longer means re-explaining your project, your tone requirements, or the background of the conversation, because the history you have already built up in one tool stops being trapped there and becomes portable. Cuey is not a replacement for the AI you already pay for. It runs alongside the assistant you use and supplies a second opinion from other models, so people who already have ChatGPT Plus can keep their existing subscription and still see how other models respond. There is nothing to configure: no API keys are required and no account is required to start, and side-by-side comparison, cross-checking, and multi-language support are free, with a daily free limit on the 30+ model cross-check. Cuey accesses the page content needed to provide model comparison and context features, and the developer states that your data is not sold to third parties and is not used for purposes unrelated to the extension's core functionality. The practical outcome is fewer bad decisions made on the back of a single confident-sounding answer. Because the comparison happens in place, there is no copy-pasting, no tab-switching, and no guessing, and users do not need to take on extra subscriptions to hear from more than one model. The extension also saves the time that would otherwise go into re-establishing context each time you try a new model, and it gives you a repeatable check before you commit to an answer in writing, analysis, or research. When the models agree, you can move on with more confidence; when they do not, you know to investigate further. Concrete workflows in the content include checking an AI-generated answer before acting on it, which is the scenario the extension is built around: catching a confident-sounding wrong answer before it burns you. Writers can compare how different models handle the same brief, such as ad copy, where models are described as having different strengths. Questions that depend on current information benefit from including models with real-time internet access in the comparison alongside models without it. People who move between AI tools can carry their imported history and preferences so each new model starts with context rather than a blank slate. And because comparison, cross-checking, and multi-language support are free, the workflow can be tried without a subscription commitment. Cuey is delivered as a Chrome extension published by Llama Valley Inc and distributed through the Chrome Web Store, where the listing shows version 0.1.20.9, an install size of 8.9MiB, and support for 8 languages: Deutsch, English, español, français, italiano, português (Brasil), 中文（中国）, and 日本語. The listing notes that the extension offers in-app purchases and places it under Productivity / Tools within the Extensions category. The free tier covers side-by-side comparison, cross-checking with a daily free limit, and multi-language support, all with no account required, while the publisher's stated mission is to make AI easier to use and more useful for everyday work. Cuey's value proposition is straightforward: the AI answer you already have is only one opinion, and a confident tone is not evidence of correctness. By comparing that answer against 30+ models inside the tool where the question was asked, surfacing where models agree and disagree, and carrying your context between models, Cuey makes a second opinion a normal step rather than a chore. It is free to install, requires no account to start, and adds no extra subscription if you already pay for an AI assistant.
