Cloud word processors like Zoho Writer & Google Docs already have version comparison features. But this idea of a sliding time traveler for documents is very intuitive! Also Zoho Writer has a combine feature, that lets you upload a docx and combine it with another docx - with the changes highlighted as tracked-changes. Pretty handy for comparing docx files. https://writer.zoho.com https://writer.zoho.com
