Every scan you run through the Chrome Extension goes through the same three-step process that powers Quetext's full plagiarism checker:
DeepSearch™ looks beyond individual words. It evaluates the statistical likelihood and surrounding context of phrases, catching plagiarism even when wording has been rearranged or lightly edited.
The algorithm identifies text that has been altered just enough to avoid detection by simpler tools - synonym swaps, sentence restructuring, and patchwork plagiarism all get flagged.
Each flagged passage is individually weighted against your overall document score. This gives you a nuanced plagiarism percentage rather than a simple pass/fail, so you know exactly how much of your text needs attention.
