Frequently Asked Questions
What is lexical diversity? expand_more
Lexical diversity is unique words divided by total words, expressed as a percentage. Higher values indicate a richer vocabulary; lower values suggest repetition.
How are words tokenized? expand_more
Punctuation is stripped using Unicode-aware rules, so contractions like "don't" stay intact and accented letters are handled correctly.
Can I ignore short words? expand_more
Yes. Increase the "Minimum Word Length" slider to filter out common stop words like "the", "a", and "is".
How do I deduplicate the result list? expand_more
Copy the ranked words into the [Line Sorter](/tools/line-sorter/) and enable "Remove duplicate lines".
Is my text uploaded anywhere? expand_more
No. All frequency analysis happens client-side.
