As answered by people managing CodeSignal and CodeSpy.AI.
CodeSpy.AI's answer:

CodeSpy.AI's answer:
A person should choose CodeSpy.ai over competitors because it offers dedicated, code-specific detection (not just generic text analysis), supports multiple widely-used programming languages, and emphasizes user privacy by not storing submitted code. This makes it a reliable, developer-friendly option — especially for students, educators, or teams needing to verify code authenticity.

CodeSpy.ai was created to help students, educators, and developers distinguish between AI-generated and human-written code. As AI coding tools became widespread, its founders saw a need for a reliable, privacy-focused platform that verifies code authenticity across multiple programming languages, ensuring integrity and trust in both academic and professional settings.
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.
CodeSpy.AI's answer:
CodeSpy.ai is primarily used by students, educators, and developers. While specific big customers are not publicly listed, the platform serves academic institutions, small software teams, and individual developers who need to verify code authenticity.
