The only redline tool made for the Mac.
Litera and Draftable are capable tools, built for Windows and sold to firms on annual contracts. On a Mac or an iPad they work only through a browser or a Word add-in. Fredline was made for the Mac and iPhone first, and it runs in any browser on Windows too. Wherever you use it, your documents stay on your computer.
