Download on the Mac App Store

Filter the list of changes, discard any of them, and export the resulting file.

Compare any of the listed files inside two compared directories, or reset a modified file to its original state.

Copy and paste two texts and compare them.

Export patches from two compared text files, or apply saved patches to an existing file.

Create edit scripts that can be applied non-destructively to any text file and export the resulting text.

I created Patchword because I couldn’t find an app for comparing files that was flexible, easy to use and affordable. If you have any problem to report or a suggestion for a new feature, I’m always happy to help!
