Try it yourself with Replit Agent
I have [number] hours to build an app for [cause or event, e.g. a book donation drive]. Build a working version where users can [core action, e.g. list books they want to donate and find a drop-off point], with a simple clean design. When it works, write a 60-second demo script I can record, and pause before deploying publicly.
