AI coding assistant from Replit, originally branded Ghostwriter, for code generation, completion, explanation, transformation, and AI-powered app development.

Replit Ghostwriter was Replit's AI coding assistant designed to help developers write, understand, transform, and generate code directly inside the Replit development environment. Its original features included real-time code completion, code explanation, code generation, and code transformation. Replit later retired the Ghostwriter name as a standalone AI branding and integrated AI capabilities throughout its platform. Today, Replit's AI experience centers on Replit Agent, which can build and refine applications from natural-language instructions, search the web when needed, work with databases and authentication, and support complex software development workflows. The Ghostwriter name remains relevant historically because many developers know Replit's AI coding features by that name.
