Revision History

Revision History shows you how a Google Doc was actually written — not just the final text, but the whole story behind it. Open any doc you can edit, click one button, and watch the writing replay from the very first keystroke to the last. Built for teachers in the age of AI writing, this revision history extension turns Google Docs' hidden edit data into a clear, watchable timeline. See the writing process unfold, spot where large blocks of text appeared at once, and understand how a document really came together — all without leaving the doc. ➤ WHAT REVISION HISTORY DOES 1️⃣ Replays the full writing process of a Google Doc, edit by edit 2️⃣ Shows a visual timeline you can play, pause and scrub through 3️⃣ Highlights large inserts, so you can see where big blocks arrived at once 4️⃣ Counts writing sessions and active time spent in the doc 5️⃣ Works on any tab of a multi-tab document Google Docs already records every edit — this extension simply makes that revision history visible. Where the built-in version history shows a few named checkpoints, the revision history replay shows the real motion of writing: typing, deleting, pausing and rewriting. ➤ WHY TEACHERS USE IT Teachers use revision history for Google Docs to move the conversation from "what did you write" to "how did you write it". Instead of guessing, you can watch the writing process and let the timeline speak for itself. 💡 See whether a document grew steadily or arrived in a few large pastes 💡 Review the editing history of a draft before a one-on-one conference 💡 Give feedback on process, not just the final product 💡 Help students prove their own work with an honest record of their writing This is not a plagiarism scanner and not an AI detector. A large insert can be a paste, but it can also be autocomplete, dictation or a moved paragraph. Revision History shows you what happened and leaves the judgment to you — the teacher who knows the student and the assignment. ➤ HOW IT WORKS - Open a Google Doc you have edit access to - Click the Replay writing button in the corner of the page - Press play, or drag the timeline to any moment in the writing process - Read the edit history at your own pace, at real speed or sped up There is nothing to set up. The Google Docs revision history is read straight from the page you already have open, and the replay starts in a single click. ➤ WHAT YOU SEE ON THE TIMELINE ▸ The document rebuilding itself from the first word to the last ▸ Writing sessions — when the work happened and how long it lasted ▸ Large inserts flagged on the timeline for a closer look ▸ Total characters typed and deleted across the whole editing history ➤ FOR STUDENTS Revision History is not only for teachers. As a student, the revision history of your own Google Doc is proof of your work. If your writing process is ever questioned, you can replay the whole thing and show exactly how the draft grew, word by word, session by session. - Keep an honest record of your writing process - Replay a paper before submitting to review your own editing history - Show a teacher the revision history behind a draft you are proud of ➤ REVISION HISTORY vs BUILT-IN VERSION HISTORY Google Docs already has version history under File, but it only shows a handful of named checkpoints. The revision history extension goes deeper: instead of a few saved versions, it replays the continuous writing process — every insert, every deletion, every pause — as one smooth timeline you can scrub through. It is the difference between a photo album and a film of the same document. ➤ MADE FOR THE CLASSROOM Revision History fits the way teachers already work in Google Docs. Open a student's draft, replay the writing process, and talk about how the work came together — the revision history turns a finished page back into the story of how it was written, so feedback lands on process, not just the final result. ➤ GOOD TO KNOW - Revision History needs edit access to a Google Doc. A view-only doc shared by link has no editable revision history, so it cannot be replayed — by anyone. - Brand-new documents have no revision history yet; the timeline fills in as the writing process happens. - The replay shows text. Images and complex formatting are not drawn on the timeline, so an image-only document will look sparse. ➤ QUESTIONS Does this work with Google Docs version history? Yes. It reads the same underlying edit history that powers Google Docs version history, and turns it into a replay of the writing process instead of a list of checkpoints. Can I control the replay speed? Yes. Play, pause and scrub the timeline, or speed the writing process replay up to move through a long revision history fast. Does it work on multi-tab Google Docs? Yes. Revision History replays the writing process on any tab of a multi-tab document, so the full editing history is one click away. Watch how any Google Doc was written. Add Revision History and press play.
