Why Remove Duplicate Words
Accidental word repetition ("the the quick brown") creeps in during fast typing, dictation, or machine-generated content. This tool scans your text and keeps only the first instance of each word, producing cleaner, more readable copy. Use the consecutive-only mode to fix typos without touching legitimate repeats elsewhere in the text.
