AI Code Detector - Detect AI Generated Code

Advanced AI code detector that identifies whether code is written by AI tools (ChatGPT, Claude, GitHub Copilot) or humans. Free online tool with 90%+ accuracy for Python, JavaScript, PHP, C/C++, and Java.

Free AI Code Detector - Detect AI Generated Code Online

Our code detector is the most advanced free online tool for detecting whether code is written by artificial intelligence or humans. Using sophisticated pattern recognition and machine learning algorithms. This tool analyzes coding style, naming conventions, comment patterns, and language-specific behaviors to determine code authorship with over 90% accuracy.

Whether you need to detect ChatGPT generated code, GitHub Copilot code, Claude AI code, or other AI-written programming, our detector provides instant, accurate results. This makes it the perfect tool for educators, code reviewers, and developers who need to verify code authenticity.

How Does the AI Code Detector Work?

Our tool employs a multi-layered analysis approach:

  • Naming Pattern Analysis: Detects human-like abbreviations vs AI's verbose naming
  • Comment Style Detection: Identifies formal documentation (AI) vs brief comments (human)
  • Language-Specific Patterns: Recognizes bad practices and legacy syntax humans use
  • Code Structure Analysis: Evaluates consistency and formatting patterns

Supported Programming Languages

Our AI code detector supports comprehensive analysis for:

  • Python: Detects PEP8 violations, wildcard imports, old string formatting
  • JavaScript: Identifies var usage, jQuery patterns, loose equality operators
  • PHP: Recognizes short tags, legacy MySQL functions, global variables
  • C/C++: Analyzes comment styles, naming conventions, code structure
  • Java: Evaluates coding patterns and style consistency

Frequently Asked Questions

What is an AI Code Detector?

An AI code detector is a tool that analyzes source code to determine whether it was written by artificial intelligence (like ChatGPT, Claude, or GitHub Copilot) or by human programmers. It uses advanced pattern recognition to identify distinctive coding styles, naming conventions, and structural patterns that distinguish AI-generated code from human-written code.

How accurate is the code detector?

Our tool achieves over 90% accuracy in distinguishing between AI-generated and human-written code. The accuracy varies by programming language, with the highest accuracy for Python, JavaScript, and PHP due to their rich pattern recognition features.

Can the AI detector identify code from ChatGPT, Claude, or GitHub Copilot?

Yes, our it can identify code generated by popular AI tools including ChatGPT, Claude, GitHub Copilot, and other LLM-based coding assistants. Each AI tool has distinctive patterns in code generation that our detector recognizes.

Which programming languages support?

Our AI code detector supports Python, JavaScript, PHP, C, C++, and Java. Each language has specialized detection algorithms that analyze language-specific patterns, coding conventions, and common practices.

Is our AI detector for code free to use?

Yes, it is. You can analyze unlimited code snippets without any registration or payment required. Simply paste your code and get instant AI vs human likelihood scores.

What makes code look AI-generated vs human-written?

AI-generated code typically features: verbose function names, consistent formatting, formal documentation, modern syntax patterns, and few bad practices. Human-written code often has: abbreviated variable names, inconsistent formatting, brief comments, legacy syntax usage, and occasional bad practices or shortcuts.

Can I use this AI coding detector for academic or professional purposes?

Our is tool is suitable for educational analysis and research purposes. However, results should be interpreted as likelihood indicators rather than definitive proof. For academic integrity or professional code review, we recommend using this tool as part of a broader evaluation process.

How do I interpret the Human Likelihood Score?

The Human Likelihood Score ranges from 0% to 100%. Scores above 50% suggest human-written code, while scores below 50% indicate likely AI-generated code. Higher scores (80%+) indicate strong human characteristics, while lower scores (20%-) suggest strong AI patterns.
