Duplicate Word Remover
Paste any text and this tool removes repeated words, keeping only the first time each word appears while preserving the original order. It is useful for cleaning up keyword lists, tightening prose that leans on the same word too often, deduping tags, or tidying data that was pasted with repeats. You can choose to ignore case so that Dog and dog count as the same word, and punctuation attached to a word is considered part of the comparison or stripped depending on your needs. The tool also reports how many duplicate words it removed, so you can see the effect at a glance. Everything runs locally in your browser, which keeps even large blocks of text fast and completely private on your own device.
