Word Frequency Counter

See how often each word appears in your text, ranked from most to least common with exact counts and percentages. Use it to check keyword density, catch overused words, and understand your writing - all computed privately in your browser.

Words are split on spaces and punctuation, then tallied and ranked.
Hides filler words like "the", "and", "of" so keywords stand out.
Off (default) merges "Apple" and "apple" into one word.
Ignore words shorter than this many characters.

How to use the word frequency counter

Paste or type any text into the box above and the ranking updates instantly. There is nothing to submit and no button to press - the totals, the unique word count, and the table all refresh as you type or change an option.

Three options let you shape the result. Tick Ignore common stop words to strip out filler such as "the", "and", and "of" so that only meaningful words remain. Tick Case sensitive if you want "Apple" and "apple" treated as different words; left off, the tool merges casing so your counts are not split. Finally, raise the Minimum word length to drop very short words - setting it to 3, for example, removes most two-letter noise and focuses the list on substantial terms.

What word frequency tells you

Counting words is a fast way to understand the shape of a piece of writing. The same analysis serves several different goals depending on what you are working on.

Keyword density for SEO

Search-focused writers use frequency to check keyword density - the percentage of total words that match a target term. The percentage column does this math for you. A focus keyword that appears naturally usually lands around one to three percent of the text; far higher can read as keyword stuffing, while near zero suggests the page may not clearly signal its topic. Comparing the top words against your intended keyword reveals whether the page actually emphasizes what you think it does.

Spotting overused words in writing

Editors and authors use the ranking to find crutch words and repetition. If a single adjective, name, or transition dominates the list, that is a cue to vary your language. Surfacing these patterns is hard to do by eye in a long document, but a ranked count makes them obvious in seconds.

Readability and vocabulary

The ratio of unique words to total words hints at lexical variety, and a long tail of words that each appear only once suggests rich, varied vocabulary. A short, top-heavy list points to simpler, more repetitive prose. Neither is wrong - the right balance depends on your audience - but seeing the distribution helps you write deliberately.

Everything runs locally. The text never leaves your device. All tokenizing, filtering, and counting happen in your browser with JavaScript, so you can analyze drafts, private notes, or client work without anything being uploaded or stored.

Frequently Asked Questions

What is a word frequency counter?
A word frequency counter analyzes a block of text and reports how many times each unique word appears. It then ranks the words from most to least common and shows each word's share of the total. This makes it easy to see which words dominate your writing and to measure keyword density.
How are words counted?
The text is split into tokens on anything that is not a letter, number, or apostrophe, so punctuation and spaces act as separators. Each token is lowercased by default, then empty tokens, words shorter than your minimum length, and optional stop words are removed before the remaining words are tallied.
What are stop words and should I ignore them?
Stop words are extremely common words such as the, a, and, of, to, and in that carry little meaning on their own. Ignoring them hides this filler so the ranking surfaces the meaningful keywords in your text. Turn the option off when you want a raw count of every word.
How do I check keyword density with this tool?
Paste your content, optionally ignore stop words, and read the percentage column. The percentage is each word's count divided by the total counted words. For SEO, a focus keyword usually sits in a natural range of roughly one to three percent, so use the ranking to confirm you are not over-optimizing.
Is my text sent to a server?
No. All tokenizing, filtering, and counting happen entirely in your browser using JavaScript. Nothing you paste is uploaded or stored anywhere, so the tool is completely private and works offline once the page has loaded.
Does the count treat uppercase and lowercase as the same word?
By default yes. Apple and apple are merged into one entry so casing does not split your counts. Enable the case sensitive option to treat differently cased versions as separate words, which is useful for code, acronyms, or proper nouns.
