Cuey is an AI productivity tool designed to help users compare responses from multiple language models without repeatedly switching between AI services. The platform works alongside services such as ChatGPT, Claude, and Gemini, allowing users to submit a prompt within an existing AI workflow and access additional model responses through a comparison interface.

A primary feature of Cuey is multi-model comparison. Instead of manually copying the same question into several AI assistants, users can use Cuey’s browser extension to send a prompt across supported models and view the resulting responses side by side. This approach is designed for situations where users want to check how different models interpret the same question or produce different answers.

Cuey supports a range of major AI models and services, including ChatGPT, Claude, Google Gemini, Grok, and DeepSeek. The supported model selection can change as the service develops. The platform is designed to operate directly within existing AI websites, reducing the need to open multiple browser tabs for separate model conversations.

The comparison workflow can be used to cross-check research, advice, writing, and other judgment-heavy tasks. Rather than relying exclusively on one model’s response, users can inspect multiple outputs and identify areas where responses agree or differ. Cuey positions this cross-checking process as a way to reduce reliance on a single AI answer.

Cuey also provides portable AI memory. The feature is designed to help users carry context, preferences, and relevant history between supported AI services instead of rebuilding the same context whenever they change models. This allows users to compare different AI systems while retaining information that is useful to their ongoing workflows.

The platform includes a prompt library containing pre-built prompts organized into categories. Users can search the library and save frequently used prompts as favorites. The extension also supports multiple languages, making the prompt and comparison workflow available beyond a single-language interface.

Cuey is delivered primarily through a Chrome browser extension. The extension adds a sidebar to supported AI websites where users can access model comparisons and related functionality. It is designed to work inside services such as ChatGPT, Claude, and Gemini rather than requiring users to move their conversations into a separate AI chat application.

The extension is available to install without requiring an account to start. The free functionality includes AI model comparison, access to the prompt library, quick prompt templates, multi-language support, and compatibility with supported AI providers. The current public extension information also describes cross-checking against more than 30 models with a daily free limit.

Cuey also emphasizes privacy in its public product information. The extension states that it does not sell user data and that it accesses page content required for its comparison and context features. The Chrome Web Store listing provides additional disclosure about the type of website content handled by the extension.

The product is developed by Llama Valley Inc. Its public company information describes Cuey as a software-development product focused on comparing AI answers and maintaining portable context across different AI services.

Cuey’s pricing structure includes free functionality alongside paid features, although a verified current starting price was not publicly disclosed in the available pricing information. The free extension can be installed without an account, while additional capabilities may be available through paid access.
