What word frequency reveals
Repetition is invisible while you write and glaring once you read back — every writer has crutch words (“really”, “just”, “actually”) and pet phrases they reach for without noticing. Ranking your words by count makes those habits visible in seconds, and the vocabulary-variety figure (unique words as a share of total words) tells you at a glance whether a piece leans on a narrow word set.
Checking keyword usage for SEO
The density column shows each word as a percentage of the whole text, which is what SEO tools mean by keyword density. There is no magic percentage that makes a page rank — writing naturally about one topic tends to land a main term around 0.5–2% on its own. What the number is genuinely good for is catching the opposite problem: if a keyword tops your list at 4% or more, the page almost certainly reads stuffed, and search engines treat stuffing as a negative signal. Use it as a sanity check, not a target.
Phrases expose habits single words hide
Switch to the 2- and 3-word phrase views to catch stock constructions — “it is important to note”, “in today’s world”, “plays a crucial role” — that repeat across paragraphs. Formulaic, repeated phrasing is not just a style problem: uniform phrasing is one of the patterns AI detectors read as machine-like. Varying your sentence openers and swapping stock phrases for concrete ones improves the writing and how it scores.
Free, unlimited, and private

| Density | What it usually means |
|---|---|
| 0.5–2% | Natural range for a main topic word |
| 2–4% | Noticeable repetition — reread those sentences |
| 4%+ | Reads stuffed; vary the wording or cut mentions |
Frequently asked questions
What is keyword density and what should mine be?
Keyword density is how often a word appears as a percentage of all words. There is no proven ideal figure — natural writing about one topic usually lands around 0.5–2% by itself. Treat high numbers as a stuffing warning rather than chasing a target.
What does “ignore common words” remove?
It filters out function words — “the”, “and”, “of”, “to” and about a hundred more — that top every English text. With them hidden, the list shows the words that actually carry your meaning.
Can it find repeated phrases, not just words?
Yes — the 2-word and 3-word phrase tabs rank every phrase that appears at least twice, which is the fastest way to catch stock constructions you overuse.
Is my text private?
Completely. Counting happens entirely in your browser — your text is never uploaded, stored, or used to train anything.
Do I need an account?
No. There’s no sign-up and no install — open the page and start typing.
Does it work on mobile?
Yes — it works in any modern browser on phone, tablet, or desktop.
