Also a keyword-stuffing check

The most frequent words with their share of the text, the unique word count, and lexical diversity.

Frequency analysis shows what a text is really about: which words keep coming back, and how varied the vocabulary is.

The counter does not reduce words to a base form, so 'counts' and 'counting' get separate rows. If one word in several forms tops the list, that is the repetition signal.

How to use

Paste your text.
Set the minimum word length and how many rows to show; decide whether case matters.
Read the frequency list with shares, the total and unique word counts, lexical diversity and the words used only once.

The example, row by row

Fifteen words of three letters or more, eleven of them different; eight appear only once.

Every row is output from this page's counter.

What this calculator shows

The most frequent words with counts and percentages
Total and unique word counts
Lexical diversity — unique words as a share of the total

What to keep in mind

Inflected forms count separately; no lemmatisation is performed.
Minimum word length is adjustable so that articles and prepositions, which always top the list, can be filtered out.

FAQs

What keyword density is normal?

There is no single norm: search engines judge what a text means, not the share of one word. The counter shows the share so repetition is visible; whether it is too much is the writer's call.

What is lexical diversity?

Unique words as a share of all words. The shorter the text, the higher it tends to be: 73.33% on the fifteen words above.

Why are word forms counted separately?

This counter does not reduce words to their base form, so different forms of a word are counted separately. For spotting repetition it rarely matters: if one word in different forms tops the list, that is the signal.

What are the words that appear once?

They are called hapax legomena. The counter tells you how many there are: eight of the eleven unique words in the example.

What is the minimum length for?

To keep out the short function words that always lead: at three letters and up, 'a', 'an', 'by' and 'is' drop out, although 'the' stays.

Are 'The' and 'the' one word or two?

One, by default: 'The' and 'the' are one word. A switch lets you count them separately.

Worked example

A short text with repeats

Input: The calculator counts quickly. The calculator is convenient. Counting by hand takes longer than counting with a calculator.

Output: calculator — 3 (20%), diversity 73.33%

Note: 'Counts' and 'counting' are counted apart, while 'Counting' and 'counting' merge because case is ignored.
