Napkin
Get your idea off the napkin.
A small, free toolkit for brand-new founders — honest AI tools to pressure-test an idea, talk to customers, test demand and name it, without the flattery.
Most AI tools tell founders what they want to hear. Napkin is built to do the opposite: a set of small, focused tools that take a raw idea to its first customer and are honest about the weak spots along the way.
It runs on Claude, with rate limiting and cost controls so it can stay free.
