Google Docs version history and Draftback: how to show you wrote it yourself

If you're ever asked whether you wrote something yourself, the most convincing answer isn't a detector score — it's the history of the document. Google Docs and Word already keep that history, and tools such as Draftback can replay it like a video. This guide shows how to find it, what teachers see when they replay it, and how to write so that your history tells a clear story.

Why version history is strong evidence

An AI detector looks at finished text and guesses. Version history shows something a detector can't: the document growing over hours or days, with false starts, deleted sentences and rewritten paragraphs. That matters most for non-native writers, whose careful, simple English is misread by detectors far more often than native writing (Liang et al., 2023). A score is an estimate; a revision history is a record.

How to see version history in Google Docs

1. Open the document and click Last edit at the top right.
2. The version history panel lists earlier versions with who made the changes and when. Select one to see the document as it was.
3. To mark milestones — “outline”, “first draft”, “after feedback” — select a version, open More and choose Name this version. You can name up to 40 versions per document.

One limit to know: you need permission to edit a file to browse its earlier versions (Google Docs Help). If a teacher asks to see your history, share the document with edit access or walk them through it on your screen.

Draftback: replaying a Google Doc

Draftback is a Chrome extension by the developer and writer James Somers that “lets you replay the revision history of any Google Doc you can edit”. It doesn't record anything new — it presents the revision data Google Docs already keeps as a playback, with summaries of when and how long the document was worked on (Draftback).

• Who uses it: teachers checking student work, and writers who want to watch their own process.
• Privacy: Draftback says no document data is sent to any remote service; playback happens on your computer.
• Cost: it needs a paid subscription — at the time of checking, $9.99 a month or $100 a year, with lower prices for teachers.
• Not an AI detector: its creator deliberately shows uninterpreted playback rather than flagging text as suspicious.

The Revision History extension

Revision History is another Chrome extension, used mainly by teachers in Google Docs and Slides. It offers video replay of the writing process, copy-paste detection, editing analytics and pattern analysis aimed at spotting “potential AI usage” — which, like any such analysis, is a signal rather than proof. Some universities license it officially; Denison University, for example, recommends it as its writing-process tool (Denison University, 2026).

Microsoft Word version history

Word keeps version history only for files stored in OneDrive or SharePoint (Microsoft Support). A document saved only to your laptop has no history to show. To see it, select the file name at the top of the window and choose the version history option. If you want a typed-versus-pasted breakdown in Word too, Grammarly Authorship works in the Word desktop app (Grammarly Support) — see our Grammarly Authorship guide.

What reviewers look for in a replay

Teachers who replay a document usually aren't judging your typing speed. They look for a few patterns:

• One large paste of finished text with little editing afterwards.
• A complete essay appearing in minutes instead of being built up over time.
• No revision — no deleted sentences, no reordered paragraphs, no notes.

Habits that make your history convincing

1. Start the assignment in the document you'll submit — outline first.
2. Write across several sessions instead of all at once, and don't delete your notes.
3. Name versions at milestones so the story is easy to follow.
4. Paste quotes with their citation straight away, so pasted text is clearly a source.
5. If you use a proofreading tool, keep a record of what it changed and disclose it if your course asks. Our guide to proving you didn't use AI shows how to combine all of this into one clear response.
