Ask once. Four models answer at the same time, and Quartet gives you the one answer they agree on, with the places they split underneath.
Type a question. Four seats light up as GPT, Gemini, Claude and Qwen answer in parallel. When they finish, Quartet writes the quorum: the answer they support together, and a short list of where they disagree, so you can see it rather than guess it.
Every thread is remembered. Open it later, ask a follow up, and the panel picks up where it left off. Turn MEMORY off on the ACCOUNT screen and nothing is kept between threads.
A new account starts with a hundred credits at no charge. A question costs a few. No keys to paste, no setup, one username.
Made for people who already paste the same question into several chatbots and compare by hand.
