Ghostwriter is the built-in AI assistant inside the cloud-based IDE offered by Replit. It works in your browser (no heavy local setup) and helps you write code, clean up code, get explanations, refactor, generate new functions/modules, all within the Replit platform.
If you are developing in the cloud, want rapid prototyping, or are learning code and want an interactive “pair programmer” that gives suggestions and explanations, Ghostwriter makes that easier. It helps you reduce boilerplate, avoid being stuck, and iterate faster. Also good for collaborative projects via Replit’s multiplayer features.
Inside the Replit IDE, Ghostwriter watches what you type and can:
- Suggest code completions (inline) based on context.
- Generate new code from natural-language prompts (“Create a login page”, “Refactor this function”).
- Explain existing code blocks in plain English (“What does this snippet do?”).
- Transform/refactor code (“Convert to hooks”, “Use async/await”).
