Google Docs is where most coursework and a lot of client writing actually lives, so this is a fair question to ask before signing up for anything. The short answer: you can rewrite and score a Docs draft today, through the Chrome extension or by pasting into the web app. What we do not have is a native Google Docs add-on in the Workspace Marketplace, and this page says so rather than letting you find out after you sign up.
Worth knowing up front that Docs changes one thing about the workflow in a way that favours you: it keeps version history automatically. That history is the single most useful thing you own if your writing is ever questioned, and a rewrite overwrites it. More on that below, because it is the part that actually matters.
Both are available on the free tier. Neither requires installing anything into your Google account.
The Chrome extension is the closer of the two. Select a paragraph in your draft, run it, and the rewrite and the score come back without you leaving the tab. That's what most people are actually asking for when they ask about Docs. The extension page covers what it can reach.
Copy and paste still works, and it's worth saying it isn't just the fallback. Paste a paragraph into the web app, read the two versions, paste back what you keep. Slower, yes. But it forces you to look at every change before it lands in your document, and that's the step people skip when the tool writes straight into the page.
Whichever you use, go a paragraph at a time. Partly that's a quota question. Mostly it's that you'll genuinely review one paragraph, and you won't review eight pages. Be honest with yourself about which of those you were planning to do.
There's no TextSight add-on listed in the Google Workspace Marketplace yet, so opening Extensions in Docs won't find us. An add-on is built and our privacy policy describes it, but it isn't published, and an unpublished add-on isn't something you can install. We'd rather write that down than let the page imply a sidebar you can use today. The Chrome extension is the nearest working equivalent.
This is the one piece of advice on this page that could actually change an outcome for you.
Docs records revision history on its own, with a timeline of edits. If anyone ever questions whether you wrote something, that timeline is the strongest thing you own. Better than any detector score, because it shows the work happening across sessions instead of asserting a probability about the finished text.
Here's the problem. Paste a rewrite over your draft and the timeline shows a large block of text arriving in one step, which is precisely the shape you don't want it to have. So before rewriting anything you might need to defend: File, then Make a copy, and work on the copy. Thirty seconds, and your original history survives.
If you've already been accused, don't rewrite at all: the draft history is the defence, and replacing your sentences removes it. How to prove you didn't use AI lists what to gather instead.
A rewrite varies sentence length, deletes connective filler, and replaces stock vocabulary. Those are the properties detectors read. We score the passage before and after with our own detector, labelled as ours, and highlight which words changed.
Two things in a Docs draft need checking after a pass. Citations: the reference marker rarely moves but the claim around it can, and a softened claim now points at something your source didn't say. Comments and suggestions: pasting over a range can orphan existing comment anchors, so if your document is in review with a supervisor or an editor, paste into a copy.
Use Light for anything where the wording is load-bearing. Light works on rhythm and leaves vocabulary alone. Balanced edits phrasing more broadly. Maximum replaces most of the wording and is a Pro mode; the free tier covers Light and Balanced. The full check is in humanizing without changing meaning.
No. There is no TextSight add-on in the Google Workspace Marketplace, so we will not appear in the Docs Extensions menu. The nearest equivalent today is the Chrome extension, which lets you rewrite and score a selection without leaving the Docs tab, and copy and paste into the web app always works. We would rather state this plainly than imply a sidebar that does not exist.
Two ways. Select the paragraph and run the Chrome extension, which returns the rewrite and the score in place. Or copy the paragraph into the web app, read the before and after, and paste back what you keep. Work a paragraph at a time rather than selecting the whole document: it uses less of your quota and, more importantly, it is the only way you will actually review each change.
Yes, and this is worth planning for. Docs records revision history automatically, and that timeline is the strongest evidence of authorship you own. Pasting a large rewrite in at once makes the timeline show a block of text appearing in one step. If the document is one you might need to defend, use File then Make a copy and rewrite the copy so the original history stays intact.
Pasting over a range can orphan comment anchors, because the text the comment was attached to no longer exists. If your document is in review with a supervisor, an editor or a client, rewrite a copy rather than the live document. The humanizer itself returns plain text, so Docs formatting applied to the replaced range is not preserved either.
The Chrome extension is a desktop browser extension, so it does not run in the Docs mobile app. On a phone you can still copy a paragraph into the web app in a mobile browser and paste the result back, which works but is slow. For anything longer than a paragraph or two, a desktop session is the better use of your time.
Without an account, 3 rewrites a day at up to 300 words each. A free account gives 260 words per rewrite in Light and Balanced modes. The Chrome extension works on every tier, including anonymously, with its own allowance of 3 scans a day and 500 humanizer words a month; current plans are on the pricing page. Scoring a passage is the cheaper half and is often the only half you need before deciding whether to rewrite.
We cannot answer that honestly for any specific institution, and neither can any tool that claims to. What is true is that Docs revision history shows how a document was built, and a large block of text appearing at once looks different from writing accumulating over sessions. That is a reason to think about process rather than about detection, and it is why we recommend rewriting a copy rather than your working draft.
