Cuey is a lightweight Chrome extension that sits inside the AI tools you already use — ChatGPT, Claude, Gemini, Grok, and 30+ more — and quietly cross-checks answers across models in the background. It only speaks up when it finds something better, more complete, or meaningfully different.
For high-stakes tasks like research, strategy, writing, analysis, or important decisions, Cuey gives you a second opinion before you trust the first one. Its signature Meld feature synthesizes responses from multiple models into a single view, making it clear exactly where models agree, disagree, or leave gaps.
Cuey also solves the context problem: instead of your chat history and preferences being trapped inside one AI tool, Cuey makes your memory portable so every model you switch to already knows who you are.
