Word Frequency Counter

The Word Frequency Counter tallies how many times each word appears in a block of text and ranks them from most to least frequent, with optional case-insensitive matching, common-word filtering, and a minimum word length. Paste an article, transcript, or document and get back a clear table of which words actually dominate the text.

It's used to audit an article for accidental overuse of a phrase before publishing, analyze a transcript or speech to see which terms recur most, check a product description or ad copy for keyword balance, and quickly get a feel for the core vocabulary of any pasted text — a long report, a set of customer reviews, or an essay — without reading it end to end. It complements a plain word count: two documents can have the same total word count but very different word distributions, and this tool shows exactly what that distribution looks like.

Excluding common words (the built-in filter removes words like 'the', 'and', 'of' and similar high-frequency connectors) matters because without it, the top of almost any frequency table in English is dominated by the same handful of function words regardless of subject matter — filtering them out surfaces the words that actually carry the text's meaning. The minimum word length option further trims short, low-information tokens (single letters, short abbreviations) from the results when they're not useful for the analysis at hand.

Word boundaries are detected using full Unicode letter and number matching, so the counter works correctly on non-English text and on words containing accented characters, not just plain ASCII. Percentages are calculated against the total word count after filtering, giving a share-of-text figure for each word alongside its raw count.
