Word Frequency Counter
Instantly see which words appear most in any text — sorted by frequency.
What is it?
A **word frequency counter** analyses a block of text and shows you how many times each unique word appears, ranked from most common to least common. This kind of analysis — sometimes called word frequency analysis or lexical density analysis — is a fundamental technique in linguistics, content writing, SEO, and data science. Understanding the frequency of words in your writing helps in many practical ways. Writers use it to spot overused words and improve variety. SEO professionals use it to check whether target keywords appear with appropriate density without crossing into keyword stuffing. Researchers use it to study text corpora, compare writing styles, or extract key themes from large documents. Students use it to analyse speeches, novels, and primary sources for academic work. This free, browser-based tool processes any text instantly — paste a blog post, a legal document, a novel excerpt, or an email and get a ranked frequency table within milliseconds. You can filter out common filler words (stopwords) to focus on meaningful content words, sort results alphabetically or by count, and export the data to your clipboard for further analysis.
How to use it
- Paste or type your text into the input area.
- The frequency table updates instantly as you type, showing each word and its count.
- Toggle "Filter stopwords" to hide common words like "the", "a", "is" and focus on meaningful content words.
- Click the column headers to sort by frequency (default) or alphabetically.
- Use the "Copy results" button to export the frequency table as plain text or CSV.
Why use this tool
Most writing tools tell you total word count but nothing about distribution. This tool goes deeper, revealing the vocabulary fingerprint of any text. It is the difference between knowing your article is 1,200 words and knowing that "marketing" appears 18 times while "strategy" appears only twice — insight that directly improves your writing. For SEO use, keyword density is a persistent concern. This tool makes it trivial to verify that your primary keyword appears in a healthy range (typically 1–3% of total words) without mechanical repetition. You can spot accidental overuse of filler phrases or discover that an important concept you intended to emphasise barely registers. For academic and research use, the frequency table can serve as a quick concordance, helping you identify the dominant themes and terminology in any source document. Everything runs locally in your browser — your text is never uploaded to any server.
Frequently asked questions
What are stopwords?
Stopwords are extremely common words that carry little meaningful information on their own — words like "the", "a", "is", "in", "of", "and". When analysing content for themes or keywords, filtering these out helps you focus on the words that actually carry meaning.
Is the analysis case-sensitive?
No. The counter treats "Apple", "apple", and "APPLE" as the same word. All text is normalised to lowercase before counting, so capitalisation differences do not affect the results.
Does it count punctuation as part of words?
No. Punctuation is stripped before counting, so "hello," and "hello" are counted as the same word. Contractions like "don't" are treated as a single token.
What is keyword density and how do I calculate it?
Keyword density is the percentage of times a specific word appears relative to the total word count. Divide the word's frequency by the total number of words and multiply by 100. For example, if "SEO" appears 12 times in a 600-word article, the density is 2%.
Is my text stored or sent anywhere?
No. All analysis happens entirely in your browser using JavaScript. Your text is never sent to any server, stored in any database, or used for any purpose beyond the analysis you see on screen.
