This is a great extension that can definitely be useful to an educator. For me the main sticking point is that it only seems to replay activity on the main sheet of a Google Doc, and not on any tabs that may be present in that Doc. I have not been able to use this for any questionable content that occurs in a tab.

This is a very useful tool. I highly recommend it.

Amazing tool to check student's writing patterns and detect frauds.

This is a really helpful extension to use in conjunction with a solid drafting process and reviewing of drafts by the teacher. I am using it to authenticate student work for VCE. My only wish is that I could download the video replay to show students or parents what was happening.

this is absolutely absurd and do not recommend teachers to use this. I do not condone any English teacher to use this because it ruins the students day and does not prove anything otherwise. One of my students wrote his completely fair, but this didn't detect it well. I give this application a solid 1/5 stars. If so I would give it a 0 but it doesn't have a function for that. Please delete this extension for it doesn't help with any academic dishonesty, because it doesn't show any proof it was copy pasted in any sort of way.

I teach high school English, and my students do a lot of writing. Revision History allows me to see students' progress and avoid academic misconduct. I lost access to Revision History for a few weeks; nothing else compared.

Very helpful in assessing the originality and process of student work. Thank you!

Super helpful.

This has helped me to define what is unacceptable work for my high schoolers. I no longer "accuse" anyone of plagiarism or using A.I., I simply say that a text is not an original and cannot be corrected as such. It has saved my from students (and parents!) anger at hearing the word "cheater", which I could suspect but not prove. We have been able to get students to admit to using A.I. and we have been able to move on to a more productive conversation. For the original writer, It is also great to see how they write, what they changed. To see their editing process is very helpful toward making them better writers.

Very helpful in assessing the originality and process of student work.

This tool helps so much with seeing how students are writing. I had a glitch where it wasn't working recently, but when I called, the owner was able to walk me through how to get signed up again (click the puzzle piece/extension, then sign up again).

I have loved using this tool for my computer classes. I am able to have them type out paragraphs and see how they are struggling and if they are actually accurate with their typing or having to rely on the backspace for correct punctuation.

I am so unbelievably disappointed. This was the best extension for an English teacher by far. To take away the functionality midyear with no warning is just outrageous. If they want to offer new features and offer tiers, they should offer a free tier with the same functionality. Then, they can offer a paid tier with better features. And if they are insisting on keeping it as is, then they should at least let teachers choose which documents are being checked. It's May 6th and I've already used all of my 150 documents because I use a google doc to create assignments, plan, read student work as they go, etc. I hid the revision feature and thought that would prevent it from being counted, but no. I had never seen any of the data and then had it "show" the information it I was already 114 documents in. I'm just incredibly disappointed in this extension.

As a teacher, the Revision History Chrome Extension has become an essential part of my classroom practice. It’s a highly effective way to ensure academic integrity by allowing me to track student work over time and verify authentic progress. This tool helps me see who is doing the work, when it's being done, and how it's evolving—making it much easier to support students while holding them accountable. I can't recommend it enough for educators looking for a reliable and straightforward way to monitor digital assignments.

I agree with other reviewers in that not being able to choose the 150 documents to be screened has been a problem. I am losing my 150 to documents that I have created as well as student documents that do not need to be screened yet. For instance, I am skimming student documents just to look at progress - I am not even evaluating them yet. However, each time I open a document to check progress, they are taken out of my 150. It is May 5, and I have used up 67 free checks. This tool has been amazing, but I will not make it through the end of this week without going through all of my checks for the month. Considering that my students are currently and will continue to be creating writing that could easily be plagiarized or done with AI, it is unfortunate that this tool will not be able to fully aid me in the evaluation process.

I love the keystroke by keystroke replay and the analysis of whether or not there's anything unusual about the writing. By far my favorite teacher tool.

This extension is absolutely essential for teachers, especially in these days of AI. It's easy to use, has no glitches, and the customer support is first-rate. Worth every penny of the affordable subscription.

This is a great extension in every way. I wish I could tell which papers to check, however, because I'm constantly opening documents during the drafting process which I don't need to see the process. I'm going to pay for RH just during heavy grading--after students turn in a paper--and then cancel when we're not actively working on a paper.

Taking away this as a free tool was cruel.

I'm a high school teacher of ten years, and this is THE BEST tool I have ever used to check for plagiarism and cheating. I LOVE being able to see how long students have been writing on a doc - very clearly helps me flag copy-paste issues. I also use the draft replay feature. I use it suss out when and where students have used AI and then re-edited their work to sound more human. It's also useful as a tool when I communicate with students about their work, because the replay itself is striking and undeniable! Cannot recommend this add-on enough.

This is great! But I wish I could pick and choose which essays I want to examine, and not every single one that I open to grade. And then there's a price. ;( My school is too small to get a district plan, so I may have to foot the bill.

In today's modern world, this extension was a great way to gain insight into my students' writing process. I was able to determine their styles as well as catch plagiarism/AI abuse. This app also allowed me to manage groupshared documents so that I could more accurately score collaborative work. Having it at the top of each document to show me if there were large copy-pasted sections and how long the student worked on the document was so helpful... But then... they named their price. As a teacher, I am already overextended. I work at LEAST 10 hour days (if I'm lucky, it's 10...), and this tool was essential for me so that I could help my young writers develop. To have that yanked away MID SCHOOL YEAR and start asking for fees -- it was a betrayal. Our schools are underfunded, so there's no way they'll pay my subscription fee. *I* can't afford to pay my subscription fee either, and there's NO way my tax return money is going back into my classroom again this year. This is extortion. You get us hooked on a tool that really helps us do our job and help students (especially when the students can't or won't voluntarily put forth the effort to strengthen their skills), and then you rip it away and ask for money. I feel like I'm being blackmailed now. This sucks. Thanks for NOTHING, Revision History... thanks for giving me a way to do a better job then dropping me AND MY STUDENTS off the edge of a cliff. Honestly, I'd almost prefer NOT to have new tools available if I'm only going to get used to having them and then have that SHUT OFF in the middle of the school year. I saw a response to someone else's concerns "we upped the free options to 150 a month from 25 -- hope that helps." Well, it doesn't. Most secondary English teachers have at LEAST 180 students each school year (across several classes). Each class writes MULTIPLE written assignments per quarter. 150 would cut me off before I even get through ONE writing assignment... so yeah. I'm hosed. It's back to spending all those extra minutes opening up the edit history, checking each edit manually, and crying into my pillow at night when I can't get through everything I have to do for work. In a 24-hour day, I work probably 13 of those hours... I couldn't keep up even WITH this convenience, but it was a lot easier. Now...? Maybe I should just give up on helping students develop their writing. Maybe it's an exercise in futility. Who needs brains? Communication? Independent thought? We can all become cogs in the works from now on. Whirrrrr!

Revision History provides a more reliable alternative to AI detectors by allowing you to verify the authenticity of student work, and provides another valuable data point that can be used to determine whether the work presented by the student is original (other data points should be considered, as well, when making this decision and there is no silver bullet to tackle plagiarism in the digital world). This extension highlights large blocks of text that were copy-pasted during the writing process and offers a replay feature that reveals the student's actual writing behavior. When students copy from another source while typing it themselves, their writing pattern becomes suspiciously linear—like a printer outputting text or how I imagine Stephen King might write his novels—without the natural hesitations, deletions, and edits that characterize genuine composition. This makes it easy to distinguish between authentic student work and disguised plagiarism, even when students deliberately type out copied content to avoid detection.

As a high school English teacher, this product has helped tremendously in detecting AI and plagiarism. I appreciate the ability to see students' writing in real-time, examine large cuts and pastes, and then check that against the Google doc history. My suggestion to the company is: create a feature that will allow users to determine to WHICH 150 documents we want to apply it. Right now, if you're signed in, it burns through your free ones far too fast, before you realize you need to sign out, if you don't want to use it on those docs.

I love how this app works and the information it provides. But then you put up a paywall. Uninstalling and finding alternatives.

As an educator, I have absolutely loved using revision history to help with detecting AI use. I've shared it with so many people because it was a free extension. I wish they continued to make all aspects free, but I understand needing funding to better the product.

It needs to have an update feature or the ability to choose what you want to "spend" your 150 docs on. It's ridiculous that every doc you open burns a number on that 150 per month. I want to be able to choose which docs I use revision history on.

I just tried this out on myself, since we're on spring break and it totally looks worth th $30/year! Watching the replay of the writing process is probably the best part.

The new update with the requirement to pay to review an unlimited number of documents is frustrating. The number they give you is not enough. I have 120 students as a high school teacher. The free version says I can only review 25 free documents a month. That doesn't even cover one of my classes... The fact that unlimited review used to be free and is now behind a paywall leaves a bad taste in my mouth. I'll be looking into new options.

We've been using Revision History since the free version and have since upgraded to the paid. I reached out to the company regarding no longer including the deletions tracking on the toolbar - and received a quick response that told me it would be integrated back and showed me another way to learn about suspect deletion patterns.

its kinda nice to use

Revision History has been a great tool for tracking student edit history, but the new version that doesn't include how many deletions is frustrating. If a kid is retyping from ChatGPT they are more likely to have fewer deletions than if they are writing from their own thinking. Please being deletions back.

this is so bad dont use

Apparently the only option is for a paid subscription?

This new paid version has alot of bugs. It also doesn´t match up with Google Doc version history. Please fix!

I think it was updated and I need to create an account. I've tried over 10 times but I never get the confirmation email with the verification code so I can no longer use it.

The playback feature is hard to follow when the text popping up is not matching what was written or seems like nonesense words. It is effective in showing large chunks of pasted information. However, we can no longer use this feature within our board without a fee, so it's essentially useless as an app now.

This extension is a blatant violation of basic privacy rights and should be removed from the Chrome Web Store immediately. It acts as a message logger, storing sensitive data without user consent, and could easily be used to compromise personal information. The purpose of a revision history tool should never involve logging or storing private messages, and this tool goes against the fundamental principles of user privacy. I strongly recommend that this extension be banned and removed from the web store to prevent potential misuse. The presence of such a tool undermines trust in extensions and puts users at risk. It’s essential that Google enforces stricter guidelines to protect privacy and security. This tool should not be available for download under any circumstances.

I use this in my university courses to monitor student writing, and it has been very useful in this age of AI! I would love additional features that detect possible use of AI, like something that would show whether a student has used any plug-in to generate text, as I know it is becoming even easier to use these tools without copy/pasting.

It's missing known copy/pastes for some reason - I don't know if it's a bug or if the way they track copy/paste has an issue. It also still only gives 25 free docs per month despite them claiming that it's upped to 150 now. Basically completely useless, better off just using the normal version history instead of trusting this expensive and unreliable extension.

This thing is a lifesaver!

Of all the options available for similar tools, I prefer this one over the others I've tried. The toolbar at the top of the page is pretty noninvasive, but provides insights if there is any suspicious activity that needs investigated further. Combined with developing a natural ear for AI writing vs your students' writing, I think that noninvasive approach is the right one. Add to that the simple one-click that gives a further breakdown of writing sessions, copy-paste events, text-to-speech use, or abnormal single-session additions, and I think I'll continue to make this tool my "go-to." The Draft Playback is just icing on the cake to make sure that students are writing like students and not copying something down word for word from another device that has AI pulled up. I would also like to shout out Buzz R. for being very helpful and generous in helping my team get the most out of the extension after the recent update!

Another English teacher here to say I am SO grateful to have this tool available. The recent update even highlights specifically which parts are pasted in, which is super helpful. I would love if the tool also incorporated AI to detect sudden changes in writing voice.

This was a great extension. However the quick turn to a paid service has rendered it useless. I will revert back to checking a student's history manually as the limited amount of "free" uses has relegated this extension to the garbage bin.

For a product "used by so many educators", the developers seem to have little understanding of their base. Product was good for me, and a useful tool in the age of AI. Prior to this I read on the site "We are developing a premium version, but that should not affect the functionality of the base tier" or something along those lines (it has since been changed of course because it was a lie), but now I am limited to a laughable number of documents a month. The truth is, it does not matter how many documents I can look at for free, having a limit means that I cannot actually use this product without paying (which as a teacher who already has to pay out of pocket for more that I should means that I will not pay it). I have enough students that it means per month I could look at about 1 assignment with this tool. Anyway, this is a review written out of disappointment, feels bad.

This is an excellent tool to use as an English teacher.

Tryna stitch me up

As a high school English teacher, Revision History has become an essential part of my teacher toolbox. It's a simple, clean, and effective tool for helping teachers better understand students' composition processes

Love the clarity of information provided. Seeing specific patterns highlighted really helps me communicate with students and parents. In general, being able to see the genesis/"life cycle" of a document is also fantastic!

Helpful as a teacher to see exactly how long and when students worked on documents, the playback feature to watch their writing process is especially helpful! I wish it could work with other google apps, but it's very helpful for google docs!

J'ai carrément copié collé un article complet pour ensuite le scanner. L'extension me dit qu'il n'y a aucun copié collé identifié. J'ai répété l'exercice à plusieurs reprises avec plusieurs textes différents, sans succès. Je ne peux malheureusement pas me fier à cet outil pour tenter de détecter du plagiat.
