Find immediately repeated consecutive words in your text, a common proofreading check.
3
This tool flags immediately repeated consecutive words in your text (like "the the" or "is is") -- a common typo that's easy to miss while proofreading, and distinct from checking for duplicate whole lines.
Paste your text. Any repeated consecutive words appear instantly.
The finder looks for a word that is immediately followed by the very same word, with only whitespace between them. The comparison ignores capitalization, so "The the" is flagged the same way as "the the". Whitespace includes single spaces, multiple spaces, tabs and line breaks, which matters more than it sounds: a repeated word that sits at the end of one line and the start of the next is caught too, a slip that is especially common when a sentence wraps in a document.
The tool matches whole words made of letters, digits and underscores. That means "the theory" is not flagged, because "theory" is a different word that merely begins with "the". Likewise "in inside" and "is island" are left alone. Each flagged pair is shown as the word written twice in an orange badge, and the heading tile shows how many pairs were found.
Paste this passage: "We we plan to to review the the budget on Monday. Then the team meets. Meets again in June."
The count shown is 3. The result is a checklist for you to fix by hand: the tool reports what it found but does not edit or delete anything in your text, so you go back to your source and remove each extra word yourself.
Not every flagged pair is a mistake. English has real phrases where a word appears twice in a row, such as the classic sentence "That that is true is important" or "She had had enough". Names and emphasis can also repeat, as in "bye bye" or "no no no". Treat each result as a prompt to look at that spot, not as an automatic error. After reading the surrounding sentence, decide whether the second word belongs. Numbers repeated on purpose, like "1 1" in a list of values, will be flagged too, since digits count as word characters.
Duplicate words tend to appear after editing: you delete part of a sentence and rewrite it, leaving the old word next to the new one. They also show up when copy-pasting between drafts. A helpful routine is to write and edit first, run the finder on the final version, fix the flagged spots in your source, then run it once more to confirm nothing is left. Because the tool is quick, it is worth running before you send an email, submit an essay or application, publish a blog post, or paste text into a product listing, where a small typo can look careless.
Pair this tool with a read-aloud pass. Your ear often snags on repeated words that your eyes skip past, especially at the end of a line or the top of a new page. The finder catches the repeats that are visible in the text, and reading aloud helps you catch the ones separated by punctuation or wording that the tool is not designed to flag.
No -- this checks for the same word appearing twice in a row within a sentence, not whole duplicate lines. For removing duplicate lines, use a dedicated line-deduplication tool.
No. "The the" and "THE the" are both flagged, because the comparison ignores capitalization.
Yes. Line breaks count as whitespace, so a word ending one line and repeated at the start of the next line is flagged.
The tool only matches identical words separated by whitespace alone. A comma or other punctuation between them prevents a match, so review those spots by eye.
No. It only reports the repeated pairs it found. You correct the text in your own document, since some repeats such as "had had" are grammatically correct.
