Honestly, I couldn’t believe it. I only asked Claude’s latest model “Fable 5” for one thing, and a whole “app that makes apps” was finished. The model I followed was Replit. It’s a popular service where you can build apps from the browser just by instructing AI. AI assembled the same kind of system in one shot. ・Give instructions and the app is built automatically ・Preview the finished app on the spot ・Open it in the browser and edit as-is and more — the insides of a dev service basically all work👇
