What is this word frequency counter?
A free, browser-based tool that counts how often each word or term appears in your text and ranks them from most to least frequent. Paste any text — an article, transcript, survey responses, or ad copy — and it tokenizes the words, applies your filters (stopwords, minimum length, case folding), and outputs a ranked table you can copy or download as a term,count CSV. It can segment Japanese with the browser's Intl.Segmenter. Everything runs locally in your browser, so your text is never uploaded.
How to use it
- Paste your text into the box on the left.
- Turn on Japanese tokenization for Japanese text, and adjust lowercase and minimum length as needed.
- Edit the stopword list to exclude words you don't want to count (one per line).
- Read the ranked table on the right, then copy or download it as a term,count CSV.
Common use cases
- Finding the most repeated terms in an article to check focus and keyword balance.
- Summarizing open-ended survey responses or reviews by frequent themes.
- Spotting overused words in marketing copy before publishing.
