About Remove Duplicate Words

This tool scans text word-by-word and removes any repetitions. By default it operates per-line — useful for tag lists or comma-separated keywords. Enable "global" mode to deduplicate words across the entire document, keeping only the first usage of each unique word.

FAQ

Does it remove punctuation?

No — punctuation is part of the word token. "word," and "word" are treated as different tokens.

What counts as a word?

Words are separated by spaces. Punctuation attached to a word is included in the token.

Can I deduplicate CSV tag lists?

Yes — paste each tag list on a line. Duplicate tags on the same line will be removed.
