Kaleidoscope 3 is a file comparison app for Mac that aims to help you stay on top of different versions of all kinds of files. There are actually more use cases for this than you might imagine. At the more technical end of things, it allows coders to quickly compare versions of code documents that have been worked on by different people, quickly highlighting the changes and letting you copy lines of code between documents with just a couple of clicks. For more everyday users, the same can be done with text documents, say if you are an editor dealing with Word, text, or PDF documents that have been updated or changed by a writer. It’s like a track changes feature but it works independently of any particular word processing app.
