Why Synonyms Reduce Overlap
Most n-gram plagiarism scanners detect shared 3-word sequences. Replacing one word in each 3-gram breaks the match — even when the sentence still means the same thing. This tool suggests replacements for common words that show up in n-gram overlap.
What It Won't Do
It won't restructure sentences, change grammatical voice, or adjust factual claims. If your flagged text is genuinely plagiarised (copying whole arguments and structure), synonym swaps won't make it ethical or undetectable at the semantic level. Use it for light rewrites, not to disguise genuine copying.
Better Than Synonyms
The most effective plagiarism fix isn't swapping words — it's reading the source, understanding the point, then closing the tab and writing the idea from scratch in your own words. That produces text with zero n-gram overlap and a fresh voice. Use this tool only for quick mechanical passes.
