Word Frequency Counter

What is a word frequency counter?

A word frequency counter breaks a text down into every individual word it contains, counts how many times each one appears, and ranks them from most to least frequent. The result is a kind of vocabulary fingerprint — it surfaces the words a piece of writing leans on most, whether that's a meaningful recurring theme or an overused crutch word the writer didn't notice while drafting.

It's useful for editors and writers checking for repetition, students and SEO writers looking at keyword density, and anyone analyzing a transcript, review set, or survey response for the terms that come up most often.

How to use it

How the count is calculated

Text is split into words on anything that isn't a letter, number, or apostrophe, then lowercased so "Word" and "word" count as the same term. "Min word length" filters out words shorter than the chosen number of characters, which is useful for dropping short filler words like "a" or "to" without a full stop-word list. "Ignore common stop words" goes further and removes a standard list of very frequent function words — "the," "and," "of," and similar — so the table surfaces the topic-specific vocabulary instead. Percentage is each word's count divided by the total number of words counted after filtering.

Features & benefits

Why this runs entirely in your browser

Text pasted here can include unpublished drafts or private notes, so nothing is uploaded. Every word is split, counted, and ranked in JavaScript locally in the tab, which means it keeps working offline once the page has loaded and nothing typed or pasted into it persists after the tab is closed.

Common uses

Spotting overused words or phrases in a draft before editing, checking keyword density for SEO writing, analyzing the most common terms in customer feedback or survey responses, or getting a quick read on the dominant vocabulary in a speech, transcript, or long document.
