How to use the word frequency counter
- Paste your text β an essay, article, speech or product page.
- The table shows every word's count and share of the text, most frequent first.
- Keep "Ignore common words" on to filter out "the", "and", "of" and see the words that actually carry meaning.
- Use vocabulary diversity (unique Γ· total words) as a quick repetitiveness score.
Why word frequency matters
Repetition is one of the easiest writing problems to miss and one of the easiest to fix. Seeing that you used "really" 14 times or "solution" in every paragraph tells you exactly where to vary your wording. Writers use frequency analysis to tighten drafts, SEO writers use it to sanity-check keyword usage (and avoid keyword stuffing), students use it to study vocabulary in passages, and researchers use it as the simplest form of text analysis.
Benefits
- Shows exactly which words you repeat most, with counts, percentages and a visual bar.
- Common-words filter strips "the", "and" and friends so meaningful words surface.
- Vocabulary-diversity score gives a quick read on how repetitive a draft is.
- Runs entirely in your browser β paste private drafts safely.
Limitations to know
- It counts exact word forms β "run" and "running" are counted separately.
- The common-words filter is English-focused; other languages work but keep their function words.
- It analyzes single words, not phrases, so repeated two-word expressions are not grouped.
Common mistakes to avoid
- Chasing an absolute diversity score β compare drafts of similar length instead.
- Leaving the common-words filter off and concluding "the" is your top word.
- Using it for keyword stuffing β search engines penalize unnaturally repeated keywords.
Alternatives
For totals, reading time and character counts, use the Word Counter; to fix a repeated word everywhere at once, use Find & Replace.

Frequently asked questions
Is my text uploaded anywhere?
No β the analysis runs entirely in your browser. Nothing is sent to a server.
Is it case-sensitive?
No β "The" and "the" are counted as the same word.
How are words with apostrophes or hyphens counted?
Contractions like "don't" count as one word; hyphenated compounds like "well-known" also count as one word.
What is a good vocabulary diversity score?
It depends on length β longer texts naturally repeat more. Compare drafts of similar length against each other rather than chasing an absolute number.
