About this tool

Strip repeated words from text and keep only the first occurrence of each, all in your browser.

How are words split?

Text is split on any whitespace, then the first occurrence of each word is kept and later repeats are dropped.

Does it ignore letter case?

With case-insensitive on, Apple and apple count as the same word; turn it off to treat different casing as distinct.
