A browser extension that cross-checks AI answers using multiple models
Cuey is a desktop Chrome extension designed to provide a “second opinion” on AI responses. You simply ask your question as usual in ChatGPT, Claude, or Gemini, and it will compare the response to those from over 30 different models, highlighting discrepancies between their answers as well as any points your current model may have missed—all without having to copy and paste or switch tabs.
Another feature is portable memory: your background, preferences, and conversation history follow you as you switch between different AI tools, so you don’t have to start from scratch every time you switch models.
This is ideal for people who use AI to research information or as a reference for decision-making—especially when it comes to issues like health, personal finance, and law, where the consequences of getting it wrong can be significant. You can start using it for free, with no need to link a credit card. Keep in mind that even if several models agree, that doesn’t necessarily mean they’re correct; you should always verify key conclusions by referring back to the original sources.
