Free Google Docs AI detector for your docs
Check the text of a Google Doc for AI in a few seconds. Free, private, and nothing you paste is kept.
Check your textHow to read your AI detector score
The AI detector gives you a single number from 0 to 100. It is the estimated chance that AI wrote the text, not a yes or no. Here is what each band means.
Probably a person
Reads like human writing. We did not pick up the patterns a model tends to leave behind.
Hard to say
Some of it leans one way, some the other. Read it yourself before you draw a conclusion.
Probably AI
This has the marks of machine-written text. Read it closely before you conclude anything.
How to check a Google Doc for AI
Three steps, a few seconds, no setup.
Add your text
Paste it, upload a Word or PDF file, or drop in a link to the page you want to check.
We check the patterns
We weigh the text against the patterns of AI writing and human writing, whether you paste it or upload an export.
Read the score
You get a number from 0 to 100 and a plain read on how likely AI was involved.
Three ways to check a Google Doc
The quickest way is to select the text in your doc, copy it, and paste it into the box above. If you would rather not copy and paste, open the doc and choose File, then Download, and save it as PDF or Word. Then switch to the Upload tab and drop the file in. Either way you get a score in seconds.
Does Google Docs detect AI on its own?
No. Google Docs has writing and editing tools, but no built-in AI writing detector. To check whether a doc reads as AI-written, you need a separate tool like this one. It is handy for students checking their own work and for anyone reviewing a shared doc.
Share links and private docs
We cannot open a private Google Docs share link from our server. If you paste a docs.google.com URL while the doc is restricted, the fetch will fail. The reliable path is to copy the text or download the doc (File, Download, Word or PDF) and upload that instead. A doc set to "Anyone with the link, viewer" published as a web page will fetch, but the formatting can differ from what you see in editor.
What about Suggesting mode and comments?
When you copy from Google Docs, you copy the accepted text, not Suggesting-mode markup or comment threads. That is usually what you want. If a draft is mostly suggested edits, accept the ones you intend to keep before copying so the detector scores the version you mean.
Where your text goes
The check happens in memory on our own server. As soon as you have a score, your text is dropped. No logs, no database, no training set.
There is no account holding a history of your checks either.
