Replit
Replit's in-editor AI, now Replit AI
RENAMED. Replit Ghostwriter is Replit's AI coding assistant integrated directly into the Replit IDE. Offers inline code completions, chat-driven help, explain/fix blocks, test generation, and code transformations. Context-aware across entire project (not just current file). Features agentic refactors and project-level guidance. Includes Complete Code flagship feature with in-line suggestions, bug detection pointing to exact issues, and step-by-step code explanations. Supports 50+ programming languages including Python, JavaScript, Ruby, and niche languages like Rust. Runs entirely in-browser with cloud IDE. Replit renamed Ghostwriter to Replit AI in November 2024; the Ghostwriter documentation URL now returns 404.
