Why Vocabulary Frequency Matters

Spot Unconscious Repetition

Writers often develop favorite words (such as "undoubtedly", "significant", or "clearly") and sprinkle them across every page. This tool reveals your top-used vocabulary so you can introduce synonyms and elevate your prose.

Calculate Lexical Diversity

Lexical diversity measures the proportion of unique words relative to total words. Higher diversity reflects rich, varied vocabulary, which professors and academic reviewers actively look for.

Quantitative Text Analysis

Linguists, digital humanities researchers, and market researchers use word frequency tables to analyze sentiment, identify thematic keywords, and evaluate public speeches.

よくある質問

文字数カウントに関するFAQ

What is a word frequency counter?

A word frequency counter parses text to calculate the exact number of times each unique word appears and its percentage density relative to the total document length.

How does word frequency analysis help writers and students?

Writers use word frequency analysis to identify overused words, unintentional repetition, and verbal crutches (such as repeating "very", "actually", or "however"). Students use it to ensure diverse vocabulary in essays.

Can I filter out common stop words?

Yes. Enabling the "Filter Stop Words" toggle removes ubiquitous grammatical words (like "the", "a", "is", "of", "and") so you can isolate meaningful subject keywords.

Can I export the frequency data to Excel or Google Sheets?

Yes. Click "Export CSV" to download a clean spreadsheet containing word rankings, exact occurrence counts, and percentage shares.

Is this frequency counter private?

Yes. 100% of the tokenization and statistical tallying happens locally in your web browser. No document or vocabulary data is ever uploaded or saved.
