Replit AI integrates code generation and debugging into Replit's collaborative development environment, letting teams write, test, and ship code without leaving the browser. The tool sits in a crowded space—GitHub Copilot, Claude, ChatGPT all do this—but Replit's angle is convenience: AI paired with instant deployment and live multiplayer editing. The free tier lets you experiment but caps API calls; meaningful use requires Replit's paid plans, which start around $7/month for individual developers. The real friction point: you're locked into Replit's ecosystem and internet connection dependency for local-first developers.
