Word is where most serious long-form writing still happens, so this is a fair thing to check before signing up. The honest answer has two halves. You can rewrite and score Word text today by pasting it, or through the Chrome extension if you use Word on the web. What does not exist is a TextSight Office add-in, so we will not appear in your Word ribbon.
One thing that is genuinely different about Word, and it works in your favour: Word tracks changes and keeps AutoRecover versions. That record is the strongest evidence of authorship you own, and pasting a rewrite over your document damages it. More on that below.
Both are on the free tier, and neither installs anything into Office.
Copy and paste is the main route for desktop Word. Take a paragraph into the web app, read the before and after, paste back what you keep. Slower than a native add-in, and it has a real advantage: you look at every change before it lands in the document, which is the review step people skip.
The Chrome extension helps if you use Word on the web, since it can reach text in a browser tab. On desktop Word it cannot, because that's a native application rather than a web page. The extension page covers what it reaches.
Either way, work a paragraph at a time rather than selecting a chapter. Partly quota, mostly that you'll genuinely review a paragraph and you won't review twelve pages.
There's no TextSight add-in in Microsoft AppSource, so nothing appears in the Word ribbon or a task pane. We would rather write that down than let the page imply a sidebar and let you discover it after signing up. If a native Office add-in is what you actually need, we don't have one.
Worth knowing separately: our detector does accept a .docx upload directly, and paragraph breaks survive the extraction. That is the detector side. In the web app you can also humanize the extracted text of a file you've uploaded to a project; the humanizer box itself takes pasted text.
The one piece of advice here that could change an outcome for you.
Word records AutoRecover versions, and in a managed OneDrive or SharePoint tenancy it keeps a full version history with timestamps. If your authorship is ever questioned, that record is stronger than any detector score, because it shows the work accumulating over sessions rather than asserting a probability about the finished text.
Paste a rewrite over your draft and the history 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 may need to defend, save a copy and work on the copy. Your original timeline survives.
If you've already been accused, don't rewrite at all. The draft history is the defence. How to prove you didn't use AI lists what to gather.
A rewrite varies sentence length, deletes connective filler and replaces stock vocabulary, which are the properties detectors read. We score the passage before and after with our own detector, labelled as ours, and highlight the words that changed.
Three Word-specific things to watch. Formatting: the humanizer returns plain text, so bold, italics and styles applied to the replaced range are lost when you paste back. Comments and tracked changes: pasting over a range can orphan comment anchors and discard tracked edits in it, so if the document is in review, work on a copy. Footnotes and citations: reference markers usually survive but the claim around them can drift, and a softened finding leaves your citation supporting something the source didn't say.
Light, Balanced and Maximum. Use Light wherever the wording is load-bearing: it varies sentence rhythm and cuts connective filler and leaves your vocabulary alone. Balanced edits phrasing more broadly. Maximum replaces most of the wording and is a paid mode; the free tier covers Light and Balanced per our published plans. The check is in humanizing without changing meaning.
No. There is no TextSight add-in in Microsoft AppSource, so nothing appears in the Word ribbon or a task pane. For Word on the web the Chrome extension can reach text in the browser tab; for desktop Word, copy and paste into the web app is the route. We would rather state this plainly than imply an integration that does not exist.
Copy a paragraph into the web app, read the before and after, and paste back what you keep. If you use Word on the web, the Chrome extension can do it without leaving the tab. Work a paragraph at a time rather than selecting a whole chapter: it uses less quota and it is the only scale at which you will actually review each change.
No. The humanizer returns plain text, so bold, italics, styles and lists applied to the range you replace are lost when you paste back. For a heavily formatted document, rewrite in smaller pieces and reapply formatting, or work on a copy. This is a real limitation rather than something we are going to describe as a feature.
Pasting over a range can orphan comment anchors and discard tracked edits inside it, because the text they were attached to no longer exists. If your document is in review with a supervisor, editor or client, rewrite a copy rather than the live file. The humanizer itself has no awareness of Word revision marks.
Not into the humanizer box, which takes pasted text. In the web app you can humanize the extracted text of a file already uploaded to a project. Our detector does accept .docx upload directly and keeps paragraph breaks (heading styles are not preserved), so you can score a whole document that way and then rewrite the specific paragraphs that need it by pasting them. That split is deliberate rather than an oversight, and it is also the cheaper way to work.
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 all you need before deciding whether to rewrite.
We cannot answer that for a specific institution and neither can any tool claiming to. What is true is that Word version history, and OneDrive or SharePoint history in a managed tenancy, 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 work on a copy rather than your working draft.
Upload a .docx directly and score the whole document.
