Discover the telltale signs, patterns, and characteristics that distinguish AI-written code from human code with our comprehensive guide.
AI tends to over-document with comprehensive comments explaining even simple operations
Extremely consistent variable and function naming without the natural variations humans introduce
Solutions that follow textbook patterns rather than the creative approaches humans often take
Unnaturally consistent code formatting and style throughout the entire codebase
Look for overly explanatory comments that describe even simple operations in detail
AI often includes comprehensive error handling for every possible scenario
AI tends to use standard library functions rather than creative or unconventional approaches
Check for same structural patterns repeated throughout different parts of the code

// Not the most efficient but it works for my use case

* Implementation of the QuickSort algorithm.
