Teachers save time
Instead of clicking through lots of individual Google version-history entries, Revision History turns the process into easier-to-read information and a replay.
A YEAR 8 STUDENT PROPOSAL
Teachers should see how the work was made, not only the final answer.
If students complete assessments, essays, tests or presentations in Google Docs and Slides, Revision History Plus can give teachers a clearer view of the writing process.
Replay
See a document develop over time.
Paste checks
See large copy-and-paste events.
Writing time
See active work and editing patterns.
THE PROBLEM
A final document does not always show the full story.
During an assessment, a teacher may only see the finished work. That can make it hard to tell whether the student slowly developed their ideas, pasted large sections, or made meaningful revisions.
Copy and paste is easier to notice
The extension highlights paste events. A paste is not automatically cheating, but it gives the teacher something useful to check.
Real drafting becomes visible
Teachers can see sessions, edits, active writing time and revisions instead of judging only the final paragraph.
Better conversations about AI
Unusual writing patterns can start a conversation. The official tool says these patterns are not proof of AI use, so teachers still need to use judgement.
Useful with Google Classroom
Revision History works with Google Classroom assignments when the work was completed in Google Docs, making it useful for normal school workflows.
Plus removes the Docs analysis limit
The free version has a monthly Google Docs analysis limit. Plus is designed for unlimited document analysis, which is more practical for teachers marking many students.
HOW IT WORKS
Think of it like pressing replay on the writing process.
This idea came from our presentation: Revision History is like a time machine. It lets a teacher look back at how a document changed instead of only seeing the last version.
Install the Chrome extension
The teacher signs in and opens a Google Doc or Slide they have access to.
Open student work
The extension reads the document's revision information and shows writing-process data.
Check the summary
See writing time, paste counts, editing sessions and unusual patterns.
Replay when needed
Watch how the work was created and jump to important paste or deletion events.
Talk to the student
If something looks unusual, use the evidence as a starting point for a fair conversation.
WHY IT MATTERS IN ASSESSMENTS
For important work, process matters.
Exams and assessments are supposed to show what a student understands. If the work is created in Google Docs or Slides, teachers should have tools that help them understand the process behind it.
01
Fairer for students who do their own work
Students who plan, draft and revise should not be treated the same as someone who simply drops in a large amount of outside text. Process information can help teachers notice the difference.
02
More evidence than a normal AI detector
Revision History does not claim to be a perfect AI detector. Instead, it shows what happened inside the document. That gives the teacher information they can review themselves.
03
It can encourage better habits
If students know their drafting and editing process is visible, they may be more likely to plan, write, revise and use sources properly.
04
It can help teaching, not only policing
A teacher can also notice when a student barely revises, works in very short bursts, or spends a long time improving one section. That information can help with feedback.
Important: do not treat a flag as automatic proof.
Revision History's own website says unusual writing patterns may have reasonable explanations. The tool should support teacher judgement, not replace it.
FREE VS PLUS
Why the upgraded version makes more sense for regular assessment marking.
As of August 2026, the Chrome Web Store says the free tier includes analysis of up to 150 unique Google Docs per month, while Plus unlocks unlimited document analysis.
| Feature | Free | Plus |

FACT CHECK
What the tool can — and cannot — tell a teacher.
It can show writing-process information.
Replay, editing sessions, writing time, revision patterns and paste events can give useful context.
It can work with Docs and Slides.
The current extension lists support for Google Docs and a Google Slides beta.
It is designed for Google Classroom workflows.
The official listing says it works with submitted assignments when they were written in Google Docs.
It cannot prove AI use with 100% certainty.
The company says unusual patterns are a starting point for a conversation, not automatic evidence of misconduct.
PRIVACY
Schools should still check privacy and policy requirements.
Revision History says document content is processed locally for the extension and that document content is not stored on its servers. Schools should still review the official privacy policy, extension permissions and their own student-data rules before a large rollout.
OUR PROPOSAL
Give teachers Revision History Plus for assessment work.
We are not saying every unusual edit means cheating. We are saying teachers should have better information when they are marking important work. Revision History Plus can make that information quicker to access, easier to understand and available without a monthly Docs-analysis limit.
For schools that use Google Docs and Google Classroom regularly, giving assessment teachers access to Plus could support academic honesty, fairer marking and better conversations about how students write.
