Word Frequency Counter

It analyzes text and reports how often each word appears and its percentage share. Useful for SEO keyword density, writing style review, and linguistic research.

Common function words like the, a, and, is that appear frequently but carry little meaning. Excluding them surfaces the content words that characterize your text.

Hapax legomena = words appearing exactly once. Bigrams/trigrams = two/three-word sequences. Counting them reveals common phrases and collocations beyond single-word frequency.

There is no official density threshold that Google rewards or penalizes; modern ranking relies on relevance and context, not a target percentage. As a practical guideline, content writers treat anything in the low single digits as natural, while a single phrase appearing at roughly 4-5% or higher is worth a second look — it often reads as stuffed rather than conversational. The right number depends on length: in a 300-word page one repeated term inflates the percentage quickly, whereas in a 2,000-word article the same word barely registers. Rather than chasing a figure, use density as a flag to reread suspicious passages. This counter shows each word's exact count and percentage share, and its bigram and trigram views confirm whether your target phrase appears in varied, sensible contexts. Paste your draft above to see where any term dominates.

Crutch words — favorites like just, really, actually, very, and that — slip into drafts without you noticing, and the fastest way to catch them is a frequency count. Paste your text and sort the results by count, descending, so the most repeated terms sit at the top. Because filler words are often function words, toggle off Exclude Stop Words if you specifically want to see how often the, and, or that appear; leave it on to focus on content words. Scan the top of the list for anything that surprises you, then search your document for that word and vary or cut instances. The percentage column tells you how much real estate each habit occupies. This tool ranks every distinct word with its count and share, making overused terms obvious in seconds — paste a draft above to start.

Lexical diversity measures how varied your vocabulary is, calculated as unique words divided by total words — the type-token ratio. This tool reports it as a diversity ratio percentage: a higher figure means more distinct words and less repetition, while a low figure signals you lean on the same terms repeatedly. There is no universal pass mark, because the ratio falls naturally as text gets longer; a 100-word note will almost always show higher diversity than a 5,000-word report using the same style. That makes it most useful for comparing two drafts of similar length, or tracking whether an edit tightened or thinned your vocabulary. The hapax legomena count — words used exactly once — is a companion signal of richness. Paste your text above to see your diversity ratio, unique word count, and hapax total side by side.

By default the counter is case insensitive, so Apple, apple, and APPLE are merged into one entry — usually what you want, since they are the same word and merging gives an honest total. Turn on case sensitivity when capitalization carries meaning you need to preserve: distinguishing the brand Apple from the fruit apple, separating a proper noun from a common one, or auditing whether a heading style capitalizes terms consistently. Be aware that with case sensitivity on, a word starting a sentence counts separately from the same word mid-sentence, which can fragment your list and lower apparent frequencies. For most SEO and editing work, leave it off for a cleaner, truer picture. Use the toggle above to switch modes and compare the two counts instantly without re-pasting your text.

Once your text is analyzed, you can take the data elsewhere in three ways. Click Copy to put the ranked list on your clipboard for pasting into a document, or download CSV to get a file with four columns — rank, word, count, and percentage — that opens directly in Excel, Google Sheets, or Numbers for sorting, charting, or further analysis. For developers and richer workflows, download JSON instead: it bundles your chosen options, the summary metrics, and the full bigram and trigram lists in one structured file. All of this is generated in your browser, so even large texts export instantly with nothing uploaded. Adjust your filters — stop words, minimum length, maximum results — before exporting so the file reflects exactly the view you want. Paste your text above, then pick the format that fits your next step.
