You should be able to say exactly that e.g. “create a messageboard app where users can pay 21 sats to leave a message. The messages should be saved in the backend.”

Did you use Claude Sonnet 4 as the model? This will give the best results.

Oh right, you really should. I tried it after seeing BLOTTO not realizing it was made with LNfly using simple prompts. But i can't seem to to get a nice output like that.
But still very very cool for a no-coder like me. Just wish there was more details on prompt commands to get better outcomes.
