How to use Find Duplicate Words in Text
- 1. Paste your text. Enter the passage you want checked for repeated words into the input pane. The tool tokenizes on whitespace and punctuation to identify individual words.
- 2. Choose Case sensitive if needed. Turn on Case sensitive to count 'The' and 'the' as separate words. Leave it off, the default, so different capitalizations of the same word are grouped into one count.
- 3. Read the duplicate list with counts. The output lists every word that appears more than once, along with how many times it occurs, letting you quickly see which words are being overused.
When to use Find Duplicate Words in Text
Find Duplicate Words in Text lists every word that appears more than once, with an exact occurrence count for each. Use it whenever you want to catch overused words or accidental repetition without manually rereading a passage.
- Catching accidental double words. Writers sometimes duplicate a word by accident, like typing 'the the' during an edit. Scan the duplicate list for suspiciously high counts on short function words to spot such slips.
- Tightening repetitive prose. An editor wants to reduce how often a particular adjective or verb appears in a manuscript. List duplicate words with counts to see which ones are the worst offenders before revising.
- Checking keyword repetition in marketing copy. A landing page repeats a brand term so often it reads awkwardly. List duplicate words to confirm the exact count before deciding how much to trim.

About the Find Duplicate Words in Text tool
Find Duplicate Words in Text runs as plain JavaScript in your browser tab, with no server behind it. List the words that appear more than once, with their counts. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Text Tools section, 211 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
You can shape the output with the Case sensitive setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does Find Duplicate Words in Text cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
