What Is an AI App Builder?
An AI app builder is a platform that uses artificial intelligence to help you design, build, and deploy applications — without writing a single line of code. You describe what you want in plain English, and the AI generates the app structure, UI, database, and logic for you.
Think of it like having a senior developer on call 24/7, except it's free and instant.
