The validator reads for market pull, what is genuinely different and where execution risk hides, then scores each signal.

FAQ
Can an AI really validate an idea?+
No tool can tell you customers will pay. What this does is surface the assumptions you have not tested, compare the idea against known patterns and hand you the question that resolves the most uncertainty. Validation still happens in customer conversations.
Will my idea be kept confidential?+
Yes. It is processed to produce the result, stored for 14 days so you can come back to it, then deleted unless you claim it. Nothing is shared or used for training.
What makes a good target-audience description?+
Specific beats broad: 'ops leads at 20–200 person logistics companies in the UK' scores better and more usefully than 'small businesses'. The validator rewards a clear first wedge.
What happens when I claim it?+
A Nautis workspace opens with a business plan skeleton drafted from your idea, the full validation report attached and a validation Task Board for the next 30 days.
