Replit AI Agent: Build Apps in the Browser
Use Replit's AI Agent to build and run a full app without installing anything.
Lesson Notes
Replit is a browser-based IDE with an AI Agent that can write code, run it, fix errors, and iterate — all without you installing anything locally. It is perfect for beginners or quick experiments. The Agent can read your existing code and make targeted changes. Key tip: after the Agent makes a change, always read what it wrote before running it.
Your Challenge
+15 XPOpen replit.com and start a new Repl. Use the AI Agent to build a simple REST API with two routes: GET /items and POST /items. Test it with the built-in HTTP tool.
