Replit AI

Replit AI is specifically built for the browser-based Replit IDE and is the best choice if you're teaching programming, prototyping quickly, or working in an environment where local dev setup isn't viable. The 'Ghostwriter' completion model was upgraded in 2025 to use a Mixtral-based backend, meaningfully improving multi-language support. Replit Agents can deploy a full-stack app from a text description, which is genuinely impressive for beginners. The limitation: Replit AI only works inside Replit's browser IDE. If you work locally, it's irrelevant. Pricing: included with Replit Core at $20/month.
