Cuey is a Chrome extension that opens beside the chat you already have and asks the other models the same question. On its site the example is a car wash fifty meters away. ChatGPT explains the walk. Cuey's panel has already brought in Gemini and Claude, with each original on its own tab and an Enhanced Answer that says another model found a better call. It tells you to drive, and it cites three memories it already had. That memory is the second job. Context you gave one assistant is supposed to follow you to the next, so a comparison is not the same prompt pasted three times. Free is five comparisons a day and includes every model on the list: ChatGPT, Claude, Gemini, DeepSeek, and Grok, with side-by-side replies you can save. Pro is $18.99 a month for twenty-five a day, 500 MB of files, and export. It only runs in Chrome. There is no separate app.
Cuey is for the moment a chat assistant sounds sure and you are about to act on it. The product sits in the same window as the thread: your question on the left, and a panel that has already asked the other models. The useful part is not another chat box. It is the line that another model disagreed, then an Enhanced Answer that picks a side and shows which memories it used. ChatGPT will not check itself. If the work is advice, research, or a decision you would regret, that check is the job.
Skip it if you wanted something that produces the document, the clip, or the deck. Cuey does not do the work. It referees the assistant you already pay for, and only inside Chrome. Five free comparisons a day is enough to try it on the questions that would be expensive to get wrong. $18.99 a month for twenty-five is a bad trade if you only doubt an answer once a week, and still a ceiling if you want every prompt checked.
Use the free plan when one confident answer would be costly. Leave it uninstalled if you already paste the hard questions into a second model by habit, or if you do not live in Chrome.
