Check if code looks AI-generated
Paste any code snippet into this AI code detector to quickly see which language it’s written in and whether it appears to have AI-generated characteristics. It’s a simple way to review code you get from teammates, students, contractors or online sources.
The tool doesn’t give legal or definitive proof, but it can highlight patterns that are typical of AI-assisted code versus more organic, human-written code.

Detection Summary
How the AI Code Detector works
The detector analyzes the structure and style of your snippet, then combines that with language detection and pattern checks.
🧾 Paste any snippet
Drop in a few lines or an entire function from languages like Python, JavaScript, Java, C#, PHP and many others.
🔤 Language detection
The tool first identifies the most likely programming language so you can double-check that the snippet matches what you expect.
🤖 AI-style patterns
It then looks for patterns that often appear in AI-generated code, such as certain naming styles, structure and repetition.
⚖️ Human vs AI likelihood
You’ll get an indication of whether the snippet is more likely AI-assisted or more typical of human-written code, based on those patterns.
🔍 Use as a signal, not a verdict
Results should be treated as a helpful signal alongside other context, not as absolute proof of authorship.
📂 Great for reviews & audits
Use it during code reviews, academic integrity checks, technical hiring, or any situation where you want more insight into how code was produced.

Which languages does it support?
It’s designed for common languages like Python, JavaScript, TypeScript, Java, C#, C++, PHP and similar mainstream languages.
Can it prove that code was written by AI?
No. The detector provides an informed estimate based on patterns, not definitive proof. Always combine results with your own judgment.
Is my code stored?
Check the site’s privacy or terms page for details, but the intended use is to analyze snippets for you, not to publish or share them.
