Replit Ghostwriter was designed to make the distance between an idea and working code much shorter. Built into Replit’s browser-based development environment, it could help developers write code, explain unfamiliar sections, complete snippets, and troubleshoot errors without breaking their flow. Its natural-language approach made it particularly useful for turning plain-English instructions into code and learning through interactive development. Ghostwriter has since evolved into Replit’s broader AI-powered coding experience, with agentic features that can build and modify applications from natural-language instructions.
