Are there any DRYer tools for code?

I have a large code base, and there are a lot of repeating or almost repeating codes all over the place, it's about unDRY, as the code can get, but tracking “duplicates” is difficult, so I was wondering if there are any tools to find potential DRYable The code, something like a comparison tool or a Hamming distance analyzer, doesn’t need linguistic knowledge or something like that.

So some hints as a tool like this?

I heard about Simian (commercial), but have not tried.

CloneDR semantic projects detect duplicate clones that are accurate and close to zero based on the langauge structure, so it is not fooled by changes in spaces or line breaks, inserted / modified comments, or even changed variable names.

It uses parser processing fronts to work with C, C ++, C #, Java, COBOL, PHP, Python, Fortran, Ada, ...

There are several examples of website cloning analysis reports for different languages.
