Duplicate Word Remover

Summary

Duplicate Word Remover scans your text for consecutive repeated words — like "the the" or "very very very" — and collapses them to a single occurrence. It preserves capitalization, punctuation, and spacing so the output reads naturally. The entire process runs in your browser with no data sent to any server.

How it works

1. Paste or type your text into the input box.
2. Choose whether the comparison should be case-sensitive or case-insensitive.
3. Click "Remove Duplicates" — consecutive repeated words are collapsed to one.
4. Review the highlighted diff to see exactly what was removed.
5. Copy the cleaned text or download it as a .txt file.
