What this unique word counter does
This Unique Word Counter helps you see how much of a draft is built from distinct vocabulary instead of repeated wording. That makes it useful when content feels repetitive even though the message itself is correct.
It is especially useful for article intros, landing pages, product descriptions, support content, and email drafts where readers notice repeated phrases quickly.
If you want a broader composition view next, continue with Text Statistics Analyzer. If the repeated-word list shows obvious weak points, refresh the wording with Text Paraphrase Generator.
How it works
- Paste or type text into the editor.
- The tool normalizes words to lowercase and counts total words and distinct words.
- It calculates lexical diversity from the ratio of unique words to total words.
- It lists the most repeated non-trivial words so you can spot flat or repetitive phrasing quickly.
- Use the results to decide whether the draft needs rewriting, tighter editing, or more varied vocabulary.
Unique word counter examples
Check repeated wording in articles
Count unique words in blog intros, product descriptions, and support articles to see whether the same vocabulary is repeating too often.
Review SEO and landing page copy
Measure vocabulary variety before publishing pages that need to sound natural while still staying focused on a topic or keyword cluster.
Improve drafts before rewriting
Use the repeated-word list to decide which phrases need rewriting first when a draft feels repetitive or overly formulaic.
Editing notes
A low unique-word count is not always bad. Short or topic-focused copy naturally repeats terms more often than long-form editorial writing.
Repetition becomes more noticeable when the same content word appears many times in a short space, especially in intros, headlines, and landing page sections.

If a repeated word is central to the topic, that is normal. Focus mainly on repeated filler or generic wording that weakens rhythm and clarity.
Frequently asked questions
What does this Unique Word Counter measure?
It counts total words, unique words, repeated words, lexical diversity, the longest word, and the most repeated non-trivial words in your text.
What counts as a unique word?
Words are normalized to lowercase so repeated forms like Word and word count as the same word. The tool focuses on actual repeated usage rather than capitalization differences.
Why is lexical diversity useful?
Lexical diversity compares unique words to total words. It helps you judge whether the writing sounds varied or whether the vocabulary may be repeating too heavily.
Who should use this tool?
It is useful for writers, editors, marketers, students, SEOs, and anyone refining copy that should sound clear and less repetitive.
