Replit Agent is an AI coding system inside Replit's browser-based IDE that takes natural language instructions and builds functional applications from scratch — writing code, installing dependencies, configuring databases, and deploying to a live URL without leaving the browser. The collaborative editing environment lets you watch the AI build your application in real time, intervene with instructions, and test the running app immediately. Replit's cloud infrastructure handles hosting, so the gap from 'idea' to 'running URL you can share' is measured in minutes. For learners, non-developers building internal tools, and rapid prototypers who want to get to a working app before committing to a full development environment, Replit Agent removes most of the technical barriers between an idea and a deployed product.
