Frequently Asked Questions About AI Code Detection

Our AI written code detection achieves 80-90%+ accuracy when detecting AI-generated code through multi-layered neural networks trained on millions of code samples. We prioritize false positive reduction, preferring to miss AI-written code rather than incorrectly flag human-written code. When we flag code as AI-generated, it's based on concrete indicators and distinctive patterns that separate machine-generated code from human coding styles.
We can detect AI written code from ChatGPT (GPT-4o, GPT-5, GPT-5.1), GitHub Copilot, Claude (3.5, 4, Opus), Grok, Google Gemini, Cursor AI, Amazon CodeWhisperer, Meta Llama, and all major AI coding assistants. Our General AI Detection model catches any AI-generated code patterns.
We support 65+ programming languages including Python, Java, JavaScript, C++, PHP, Ruby, Go, Rust, Swift, and more.
While no AI detection system is 100% foolproof, our multi-layer fingerprint verification makes it extremely difficult to bypass. We use proprietary pattern recognition trained on LLM writing signatures that go beyond simple text analysis. Students who heavily modify AI-generated code may reduce detection confidence, but distinctive AI patterns often remain. We continuously update our models to detect new evasion techniques.
We prioritize false positive reduction, preferring to miss AI-written code rather than incorrectly flag human-written code. When we flag code as AI-generated, it's based on concrete indicators and distinctive patterns that separate machine-generated code from human coding styles.
AI detection typically takes 10-30 seconds per submission, depending on the code size and complexity. Results are generated in real-time and displayed alongside your plagiarism detection results in a unified report.
Code submissions are processed securely and can be stored in your account for your records and comparison purposes. We never share your code with third parties or use it to train external AI models. You maintain full control over your data and can delete submissions at any time.
