Free AI Code Detector

AI Code Detector

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.

AI Code Detector

Paste any code snippet to identify the language and whether it appears AI-generated.

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.
