CodeSpy.AI's answer:
CodeSpy.ai is built using advanced AI and machine learning models, natural language processing for code analysis, and multi-language parsers to understand programming syntax. It also integrates web technologies and IDE plugins to provide seamless, real-time code detection for users.
