Online IDE

Replit Ghostwriter

Replit Ghostwriter is an AI coding assistant integrated into the Replit browser IDE. It provides autocomplete, natural-language to code, and inline explanations for learners and professionals who build projects directly in the cloud. Because it lives where code runs and is deployed, Ghostwriter is particularly appealing for education, hackathons, and rapid prototyping. Users can ask it to generate functions, explain errors, or refactor snippets, all without leaving the browser. Combined with Replit’s multiplayer collaboration and instant hosting, Ghostwriter turns the platform into a full-stack development and learning environment where AI supports experimentation, debugging, and practice across many languages and project types.

How to Use

Create or log into your Replit account, then open an existing repl or start a new project from a template in your preferred language.
Ensure Ghostwriter or the AI features are enabled in your account or workspace settings; eligibility may depend on your plan or region.
While editing code in the browser IDE, start typing and watch for inline AI suggestions from Ghostwriter. Accept with the configured key or ignore them and continue typing.
Use chat- or command-style prompts to ask Ghostwriter to explain an error message, refactor a function, or generate boilerplate such as REST endpoints or test stubs.
Run your code directly in Replit to verify behavior, iterating between manual edits and Ghostwriter’s suggestions until the feature or fix behaves as intended.
Collaborate with others using multiplayer mode; all participants can see and review AI-assisted changes, ensuring that generated code is vetted and understood by the team.
