Replit Agent builds working apps from a description — backend, frontend, deployment, all of it.

The big idea
Replit Agent is wild — type 'build me a flashcard app with login' and watch it write the code, set up the database, and deploy a live URL. It's not magic (you still debug) but it's close.
Some examples
Build a personal goal tracker by describing what you want.
Create a Discord bot that posts daily quotes from a list you upload.
Make a simple game (Snake, Flappy Bird) with one chat message.
Use Replit Agent to fix bugs by describing what's broken.
Try it!
Try Replit Agent (free tier). Describe ONE small app idea. Watch what it builds. Open the code and try to follow what each file does.
