What is Mutable AI?

Mutable AI is a tool designed to automatically document and refactor existing code. It analyses your codebase and generates documentation whilst simultaneously improving code quality through refactoring suggestions. The tool is particularly useful for developers working with legacy codebases that lack proper documentation or have accumulated technical debt over time. Rather than manually documenting functions and classes or spending hours refactoring code, Mutable AI handles much of this work automatically, freeing developers to focus on new features and functionality. The tool works by scanning your existing code, understanding its structure and purpose, and then generating clear documentation alongside refactoring recommendations.
