I'm looking for a online tool that allows me to paste two versions of a text and compare the difference side by side, line by line and maybe add notes to certain changes. I found many "diff" tools that allow basic comparison (red/green) but they didn't have a "share link" functionality.
I'm correcting the text of a friend and want to send her the link to the comparison.
I know that it is possible to add comments etc. in PDF, but I need a solution where you can see both versions at the same time.
