Great tool for validating ideas before wasting weeks building the wrong thing. Every founder needs a quick gut-check like this.

Really, really cool idea 👏🏻 I just tested it with a project I built last weekend!
I've just seen Thomas! Really thanks! I'm truly aware of this 'build-check' is currently one LLM wrapper but a cool one indeed 🤣 - might be more advanced in a future!!
