Detect near-duplicate Python code using AST analysis to find structural clones despite renaming, supporting efficient AI-assisted refactoring workflows.
duphunter is a tool that helps you find pieces of Python code that look very similar. It uses a smart method that looks at the structure of your code to spot copies or parts that might need cleaning up. This helps keep your code neat and easier to understand.
You don’t need to know programming to use duphunter. It works on Windows computers and guides you through finding repeated code so you can fix it.
Before you start, make sure your computer meets these needs:
