Word Frequency Counter NZ
This tool counts how often each word appears in a block of text and ranks them from most to least frequent, giving you an instant frequency analysis. Knowing which words appear most often is genuinely useful across many tasks. Writers and editors use it to spot overused words and repetition that can be trimmed. Students and researchers use it to analyse texts and find key themes. People working on SEO and content use it to check keyword usage and density. And anyone curious about a piece of writing can use it to see its vocabulary at a glance. Counting by hand is obviously impractical for anything longer than a sentence, which is exactly where this tool helps. You paste or type your text, and the calculator breaks it into words, tallies how many times each one occurs, and lists them ranked by frequency, with the most common at the top. It also shows the total number of words and the number of unique words, a quick measure of vocabulary richness. The analysis updates as you edit the text and runs entirely in your browser, so nothing is uploaded. Use it to find and reduce repetition in your writing, to analyse the themes or keywords of a text, to check content for SEO, or simply out of curiosity. Words are compared without regard to case, so The and the are counted together, and punctuation is ignored, so a word followed by a comma or full stop still counts as the same word. The result is a clear picture of which words carry the text. A high ratio of unique words to total words suggests varied vocabulary, while a low ratio suggests more repetition.
Words are counted ignoring case and punctuation. Shows the top 50 words by frequency. A high unique-to-total ratio means varied vocabulary. Runs in your browser.
How it works
The text is converted to lower case and split into words, ignoring punctuation. Each word is tallied in a running count, then the words are sorted from most to least frequent. The total is the number of words, and the unique count is the number of distinct words. The most common words are listed with their counts.
Worked example
In the sentence about the quick brown fox and the lazy dog, the word the appears four times, making it the most frequent, followed by words like fox, dog, quick and was appearing twice each. The tool ranks these at the top, and reports the total and unique word counts for the passage.
