Frequently Asked Questions

Common questions about the free online duplicate word finder.

It splits your text into words, counts each one, and reports every word that appears more than once together with the positions where it occurs.
Any run of words of the length you choose that appears in more than one place. Set the phrase length to three for three-word repeats.
With Ignore case ticked, Word and word are treated as the same entry. Turn it off to compare only exact matches.
Positions are counted in tokens from the start of the text, so position 12 means the twelfth word-like token, which helps you find it fast.
Words shorter than the shortest-word setting are skipped, which keeps common filler words such as of and to out of the report.
No. It reports the duplicates so you can decide which ones to reword, cut or keep, which is safer than an automatic rewrite.
No. Every word is counted inside your browser, so the document you paste never leaves your device.
