A word list cleaner for puzzle makers
Instant and private
Everything runs in your browser while you type — your list never leaves your computer.
Repeat report
See which words appeared more than once and exactly how many times, most repeated first.
Ignore upper and lower case
Apple, apple and APPLE count as one word; the first spelling is kept.
Remove accents and diacritics
café becomes cafe, Straße becomes Strasse, Łódź becomes Lodz — and accented and plain spellings count as one word.
Letters only
Drop digits, hyphens and apostrophes, so every word fits a word search grid as printed.
Sort, copy or download
Keep your order or sort A–Z, switch to UPPERCASE or lowercase, separate by lines or commas and copy or download a .txt file.

Duplicate word remover FAQ
Is this duplicate word remover free?
Yes. No sign-up and no limits — clean as many lists as you like.
Is my word list uploaded anywhere?
No. The list is processed in your browser and never sent to a server.
Which separators does it understand?
New lines, commas, semicolons and tabs. Turn on Split on spaces to turn a sentence or a paragraph into a word list.
What does removing diacritics do?
Accented letters become plain ones (é → e, č → c, ß → ss), and words that differ only by accents — café and cafe — count as one word.
Why remove duplicates from a word search list?
A word hidden twice in one puzzle confuses solvers, and repeated words across a book make it feel repetitive. Cleaning the list first keeps every word unique.
Can I make a puzzle book from my list?
Yes. Paste the clean list into the Wisdom Effect word search or word scramble generator and export a print-ready book for Amazon KDP.
