Word Frequency Counter

Paste any text and the tool tokenizes it (Unicode-aware, so it handles non-Latin scripts), counts every word, and shows the top N sorted by frequency with a bar chart per row. Toggle stopword stripping to filter out the 100+ most common English filler words (the, a, of, to…). Useful for SEO keyword density, content analysis, essay editing, or finding overused words in your own writing.

Without stopwords the list is the same every time, because English is dominated by its function words: the alone is around seven percent of ordinary prose, and the top ten words account for roughly a quarter of it. That is a property of the language rather than of your text, which is why stripping them is what makes the tool say anything about what you actually wrote.

Tokenising by whitespace and punctuation is the right default and has known limits. Inflected forms count separately, so run, runs and running are three entries rather than one, and a phrase that matters as a unit is split into its parts. Hyphenated compounds and possessives land on one side or the other depending on the rules, and for languages that do not put spaces between words, Chinese and Japanese among them, per-character or per-run counting is not the same thing as counting words at all.

Keyword density as an SEO measure is worth treating with suspicion. It was a real ranking factor two decades ago and has not been one for a long time; search engines match meaning rather than repetition, and a page written to hit a percentage reads worse to a person and no better to a crawler. The useful reading of this list is the opposite one: a word you did not intend to lean on appearing near the top is a signal about your prose.

The counts are case-folded and punctuation-stripped, so The and the are one entry. Anything that depends on the distinction, a proper noun that is also a common word among them, needs a different tool.
