Revision History is a Chrome add-on developed by Revision History. It is a free tool designed for teachers to monitor and guide students' writing process in Google Docs. This add-on allows teachers to have a comprehensive view of students' revisions, ensuring that the work is original and not copied from other sources.

With Revision History, teachers can easily track the following information:

• The number of edits made by students on their essays.
• The time spent by students in writing their essays.
• Snippets of text that students copy and paste.
• A new feature in beta that enables teachers to watch a video replay of the document being written.

This add-on is compatible with documents submitted through Google Classroom, as long as they were drafted in Google Docs. Revision History is a valuable tool for teachers to analyze students' writing process and provide effective guidance for revisions.
