Remove Duplicate Words

By default it compares words case-insensitively (so "The" and "the" count as the same word) and keeps the first occurrence, removing later repeats while leaving everything else in its original order.

It removes only the repeated word tokens themselves; punctuation and spacing around the remaining words are preserved as closely as possible, though heavily repetitive text may end up reading unusually since duplicates are gone.

Across the whole text by default - a word that appears once in an early sentence and again in a later one is still treated as a duplicate. This is useful for cleaning up repetitive drafts or copy-pasted content.
