What is Word Frequency Counter?
This word frequency counter is a text analysis tool. Paste any text and it splits words on spaces and punctuation (English and Chinese), counts occurrences, and shows the top 50 ranked by frequency with a bar chart. Totals update live: the full word count and the number of unique words. Optional toggles include case sensitivity (off by default, merging "The" and "the") and ignore common words (on by default, skipping the, and, is, etc.). Analysis runs locally — your text is never uploaded. Useful for SEO keyword research, writing checks, text-mining teaching, and report frequency analysis.

What is a word frequency counter?
An online text analysis tool. Input: any text. Output: per-word counts, total and unique word counts, and a Top-50 bar chart. Used for SEO analysis and writing checks. Runs locally.
Does it support Chinese?
Yes. The tokenizer matches both English word sequences and Chinese characters ([a-zA-Z一-鿿]+); Chinese is counted per character.
What does case sensitivity do?
When enabled, "The" and "the" are separate; when disabled (default), text is lowercased first and they merge.
Which common words are ignored?
Roughly 120 high-frequency function words and pronouns: the, a, an, is, are, and, of, in, to, for, and more.
Why only 50 words shown?
For readability the chart shows the top 50 most frequent words, which covers most analysis needs.
How accurate is it?
Counting follows standard regex tokenization, and punctuation is excluded automatically.
Is my text uploaded?
No. Analysis happens locally with no network requests.
Can I export the results?
Yes. Copy the word list as text, or download as CSV for spreadsheet analysis. The bar chart is also available as a screenshot.
How are phrases handled?
Each word is counted individually. Multi-word phrases are not grouped — "ice cream" counts as "ice" (1) and "cream" (1). For phrase-level analysis, consider n-gram tools.
What is the maximum text length?
No hard limit. Texts up to 100,000 words analyze in under 1 second. Very long texts may take a few seconds depending on device performance.
