What is word frequency analysis used for?

Word frequency analysis is used in SEO to identify overused or underused keywords, in academic writing to check for unintentional word repetition, in content editing to improve readability, and in data science as a basic NLP (natural language processing) technique for text analysis.

What are 'common words' and why would I ignore them?

Common words (also called stop words) are high-frequency function words like 'the', 'a', 'is', 'in', 'and', etc. They appear in almost every text but carry little meaning. Ignoring them lets you focus on the meaningful content words — the nouns, verbs, and adjectives that actually matter for your analysis.

Does the word frequency counter support languages other than English?

The tool counts any word-like token (sequences of letters, apostrophes, and hyphens) which works for most Latin-script languages. However, the built-in stop words list is English-only. For other languages, you can disable 'ignore common words' and set an appropriate minimum word length to get useful results.

What does the frequency percentage represent?

The percentage shown next to each word is its share of the total counted words (after applying your filters). For example, if 'design' appears 15 times and there are 300 total filtered words, its frequency is 5%. The bar shows the word's count relative to the most frequent word in the results.

Is my text data kept private?

Yes. All analysis happens entirely in your browser using JavaScript. Your text is never sent to any server, so sensitive documents — contracts, drafts, private notes — remain completely private.
