What is a word frequency analyzer?

A word frequency analyzer counts how many times each word appears in a piece of text and ranks the results. It helps writers spot overused words, SEO professionals measure keyword density, researchers identify key themes, and developers debug log files.

What are stop words and why would I filter them?

Stop words are extremely common words like 'the', 'a', 'is', 'and', and 'of' that carry little meaningful information on their own. Filtering them removes the noise so the frequency table shows only the substantive words that reveal the real content of your text.

Is my text sent to a server?

No. All analysis runs entirely inside your browser using JavaScript. Your text never leaves your device and is not stored anywhere. This makes the tool safe for sensitive documents.

How do I export the results?

Click the 'Export CSV' button below the results table. Your browser will download a CSV file containing the word, count, and percentage for every entry currently displayed. You can then open it in Excel, Google Sheets, or any spreadsheet app.

What is the maximum text size I can analyze?

There is no hard limit. The analyzer runs entirely client-side so it can handle very large texts — tens of thousands of words — without any slowdown. Performance depends only on your device.

Can I analyze text in languages other than English?

Yes. The word splitter works with any language that uses spaces between words. The built-in stop-word list is English-only, so simply leave the stop-word filter off when analyzing text in another language.
