About the tool
What Unique Word Finder does
The unique word finder reads a piece of text and returns every distinct word exactly once. Words are compared in lowercase, so “The”, “the” and “THE” count as one word. The list keeps the order in which each word first appeared, and the status line shows how many distinct words were found.
It is useful for checking the vocabulary of an article, preparing a word list from a transcript, spotting how varied a draft is, or collecting terms for a glossary or keyword review. If you also need to know how often each word occurs, use the Word Frequency Counter instead.
How to use
- Paste your text. Any length works; a few paragraphs or a whole chapter.
- Run the tool. The result appears as one word per line.
- Check the count. The status line reports the number of distinct words.
- Copy the list. Paste it into a spreadsheet, glossary or editor.

Questions about Unique Word Finder
Practical details about input, output, privacy, limits, and the best way to use this tool.
01 How does the unique word finder decide what a word is?
A word is a run of letters or digits, optionally joined by an inner apostrophe or hyphen, such as “don’t” or “well-known”. Other punctuation is ignored.
02 Is the comparison case-sensitive?
No. All text is lowercased before comparison, so the output list is lowercase.
03 Does it show how many times each word appears?
No. It lists each word once. For counts per word, use the Word Frequency Counter.
04 Does it treat “run” and “running” as the same word?
No. The tool compares exact word forms and does not do stemming or lemmatization, so “run”, “runs” and “running” are three entries.
05 Are numbers counted as words?
Yes. Sequences of digits such as 2024 are listed like any other word.
06 Does it work with Ukrainian, Russian or other non-Latin text?
Yes. Letters from any script are recognised, and lowercasing follows Unicode rules.
07 What happens to curly apostrophes?
A typographic apostrophe (’) is recognised inside a word but is removed from the output, so “don’t” appears as “dont”. A straight apostrophe (') is kept. Replace curly apostrophes first if you need exact forms.
How the unique word finder works
The tool lowercases the input, extracts words, strips any characters that are not letters, digits, apostrophes or hyphens, and keeps the first occurrence of each. The result is a plain list and a count in the status line. Nothing is sorted, so the list reads in the same order as your text.
What a unique word count tells you
The number of distinct words relative to the total number of words is a rough measure of vocabulary variety. A short product description repeats its key terms on purpose, while a long essay should introduce new words steadily. Use the count as a hint, not as a quality score. Compare the total from the Word Counter with the distinct count here to see how repetitive a text is.
Common uses
- Editing: spot repeated words and see which terms carry the text.
- Glossaries and study lists: collect all terms from a lecture transcript or chapter.
- SEO and content review: check which terms appear on a page before comparing them with target keywords.
- Data cleaning: get a quick vocabulary of survey answers or comments.
Limits to keep in mind
The finder compares exact word forms, so inflections count separately. Typographic apostrophes are dropped, and abbreviations with dots, such as “e.g.”, become “e” and “g”. To remove repeated words from the text itself while keeping the rest, use Remove Duplicate Words.
