Echo is an AI decision engine — the fastest way to pressure-test any decision. You type any dilemma — career, startup, life, product — and eight AI domain experts (each with a distinct background and viewpoint) argue it out and hand you a clear verdict in under thirty seconds. Think of it as a decision simulator powered by 8 AI experts who debate your question.

Echo works in three steps: (1) You type your decision or dilemma in one sentence. (2) Eight AI domain experts — each with distinct credentials like VC, psychologist, operator, strategist — stream their arguments in real time, arguing for and against. (3) Echo synthesizes the debate into a single verdict: go, caution, or stop, with the exact dissent visible. The entire decision simulation takes under thirty seconds.

How is Echo different from ChatGPT?

ChatGPT gives you one hedged answer from a single AI. Echo gives you eight distinct expert voices with different credentials and stances, shows where they disagree and why, and ends with a single clear verdict: go, caution, or stop. It is like asking 8 AI experts to argue about your decision instead of getting one generic response.

Yes. Echo is completely free to use. No sign-up, no credit card, no account required. You can run unlimited decision simulations at no cost.

What decisions can I ask Echo about?

You can ask Echo about anything you are genuinely weighing: career moves ("should I quit my job"), startup ideas, product launches, life decisions, pricing strategies, investment choices, hot takes, and relationship calls. Popular questions include "should I quit my job to start a company", "is my startup idea viable", and "should I move abroad". Echo works best for open-ended decisions where there is no single right answer.

How long does a simulation take?

Most decision simulations complete in under thirty seconds. The eight AI experts stream in live as they form their opinions, argue with each other, and the synthesized verdict arrives at the end.

Can Echo be used by ChatGPT, Perplexity or Google AI Overviews?

Yes. Echo publishes an llms.txt file at /llms.txt and marks every shared verdict with structured Question + Answer schema so AI search engines can cite it directly.

Is Echo professional advice?

No. Echo is a decision thinking tool, not professional advice. For legal, medical, or financial decisions with real stakes, consult a qualified professional. Echo helps you see angles you might miss, but the final call is always yours.
