Get startedGetting startedAlethe puts several leading AI models in one real conversation about your question: they see everything said, build on each other, push back when they disagree, and converge on a single, better-reasoned answer. Here's how to start yours in under a minute.
In shortSign in, type a question, pick a mode, and watch models like GPT, Claude and Gemini talk it through: agreeing, disagreeing and refining the answer together. A live agreement score shows how much they're converging, and you decide when to stop.
What is Alethe?Most AI tools give you a single model's opinion, phrased with total confidence, even when it's wrong. Alethe takes a different path: it puts several of the world's best models in one continuous conversation, where they see everything that's said, build on each other, push back when they disagree, and refine the answer together.The result isn't just an answer, it's an answer that survived scrutiny. You see who said what, where the models agreed and where they clashed, and a live agreement score that tracks how far they've converged. Alethe (from the Greek aletheia, 'truth') is built on one idea: truth holds up better to contradiction than to applause.

Run your first debateA debate always starts the same way: a question and a mode. Here's the full flow.1
Open the appHead to the New screen, the launch pad for every debate. It's a single input box with the available modes underneath.
2
Ask a real questionType anything you'd ask an expert: a decision to make, a claim to fact-check, a piece of code to review, a plan to stress-test. The more specific the question, the sharper the debate.
3
Pick a modeThe mode sets how the models behave, not which models run. Start with Super Intelligence, the default: an open-ended group conversation with no fixed end, where the models build on and challenge each other. The Modes page covers the full list.
4
Follow the conversationThe models speak one after another, in real time, each one seeing everything said so far. Follow it as it streams in, and drop in a message at any point to steer where it goes.
5
Watch the agreement score: and stop when you're readyThere's no forced ending and no automatic verdict. A live agreement score shows how much the models are converging: high means they're reaching the same conclusion, low means the question is genuinely contested. The conversation keeps going until you stop it (or you reach your plan's limit), so you stay in control of when you have your answer.
