Duplicate Word Remover
Remove repeated words from text — fix accidental double words like 'the the' or strip all duplicates per line, with counts of what was removed.
About the Duplicate Word Remover
Accidental double words — 'the the', 'is is', 'and and' — slip past even careful eyes, especially across line breaks. This duplicate word remover cleans them up instantly: paste your text and the consecutive mode deletes every immediate repeat while leaving everything else untouched, including punctuation and line structure.
Need heavier deduplication? Switch to global mode and every repeated word within a line is removed, keeping only its first occurrence — useful for cleaning keyword lists, tag collections and data extracts where each term should appear once. Working line by line means multi-paragraph prose isn't gutted by a single common word appearing twice in different sentences.
A case-sensitivity toggle controls whether 'The' and 'the' count as the same word, and the results panel reports exactly how many duplicates were removed alongside before-and-after word counts. Everything runs in your browser with instant results and a one-click copy.

Frequently Asked Questions
What's the difference between consecutive and global mode?
Consecutive mode only removes a word when it immediately repeats — 'really really good' becomes 'really good' — which is the safe choice for prose. Global mode removes every later occurrence of a word within the same line, keeping just the first, which suits keyword lists and tags but would mangle normal sentences.
Why does global mode work line by line instead of on the whole text?
If it deduplicated across the entire text, common words like 'the' would survive only once in the whole document and prose would be destroyed. Per-line scope keeps lists clean (one term per line or comma-separated on a line) while limiting collateral damage; for whole-document line dedupe, a sort-lines tool with unique mode is the better fit.
Does punctuation stop duplicates from being detected?
No — words are compared by their letter-and-digit core, so 'hello, hello!' is recognized as a duplicate pair. The punctuation attached to kept words stays exactly where it was, so your sentences remain intact after cleaning.
Will 'The' and 'the' be treated as the same word?
By default yes — comparison is case-insensitive, which catches the common 'The the' typo at sentence starts. Tick the case-sensitive box if you're cleaning data where capitalization distinguishes items, like code identifiers or product codes.
How can I see what was removed?
The stats row shows the number of duplicates removed plus word counts before and after. For a word-by-word audit, paste the original and cleaned versions into a text-compare tool and the removals are highlighted precisely.
