Then compare.
Non-destructive editing.
Create edit scripts that can be applied non-destructively to any text file and export the resulting text.

About
I created Patchword because I couldn’t find an app for comparing files that was quick, easy to use and affordable.
Every now and then I find myself in a situation where I need to compare two texts. Before creating Patchword, I would either compare them manually (which was error-prone and could take a long time) or use other tools that didn’t give me the immediate result I was looking for. I was constantly evaluating which method of comparing texts was the quickest one and whether it was worth the effort. Now I can just launch Patchword, paste two texts or drop two files, and go on with my work.
