Remove repeated words from your text
Duplicate words creep into text in several ways: accidental double-typing while editing, speech-to-text stuttering, copy-paste errors, or programming bugs that concatenate the same string twice. This tool quickly removes unwanted repetition.
Two modes are available to suit different needs:
- Consecutive duplicates: removes only immediately adjacent repeats. "the the cat sat on the mat" → "the cat sat on the mat". The second "the" later in the sentence is kept because it is not consecutive.
- All duplicate words: keeps only the first occurrence of each unique word across the text. Useful for keyword deduplication or list cleaning.
Common use cases:
- Transcription cleanup: fix speech-to-text "the the" errors
- Writing proofreading: catch accidental word repetition during editing
- Keyword lists: deduplicate tag or keyword lists
- Data cleaning: remove word-level duplicates from structured text
For removing duplicate lines rather than words, see our Remove Duplicate Lines tool. For removing extra spaces between words, see Remove Extra Spaces.
