Takes any code file and transforms it into a teaching resource by adding educational comments that explain syntax, design choices, and language concepts. Automatically expands files by 125% with targeted explanations while preserving original formatting and functionality. Configurable for different skill levels and comment density. Best for onboarding new team members, creating code examples for documentation, or turning working code into tutorial material. The line numbering system helps connect related concepts across the file. Handles encoding detection properly so it won't break your builds, which matters more than you'd think.
