Unique Word Counter
Count how many distinct, unique words a text uses — its vocabulary size.
Vocabulary, not just volume
Total word count tells you how long a text is; unique word count tells you how varied it is. This counts the distinct words — treating repeats as one — so you can measure the size of a text's vocabulary, spot writing that leans on the same few words, or compare the richness of two pieces of the same length.
Paste the text and it reports how many different words it contains.
What the ratio reveals
The relationship between total and unique words is telling. A long text with few unique words is repetitive; one with a high proportion of unique words is varied, and sometimes harder to read. Writers use this to check they are not overusing a handful of terms, and it is a simple measure of lexical variety that a plain word count completely hides. Common short words still count as unique words, so the meaningful comparison is between similar texts.
Common questions
What is a unique word count?
The number of distinct words in the text, counting each repeated word only once.
What does it tell me?
How varied the vocabulary is — a low unique count against a high total means the writing is repetitive.
