Understanding the metrics

• Unique words — Number of distinct words (case-insensitive, e.g., "The" and "the" count as the same)
• Total words — Total number of words, including repetitions
• Lexical diversity — Percentage of unique words relative to total words. Higher = more varied vocabulary
• Diversity rating — Excellent (>60%), Good (40-60%), Fair (20-40%), Poor (<20%)

What is considered a "word"?

• Words are separated by spaces, punctuation, and line breaks
• Numbers (e.g., "123") are counted as words
• Hyphenated words (e.g., "well-being") count as one word
• Contractions (e.g., "don't", "it's") count as one word
• Case is ignored — "Hello" and "hello" are the same word
• Common stop words (the, and, of, to, etc.) are included in the count

Use cases

• Essay writing — Avoid using the same words repeatedly
• SEO content — Check keyword diversity in articles
• Language learning — Measure vocabulary range
• Creative writing — Identify overused words
• Academic papers — Ensure varied terminology

Tips to improve diversity

• Use synonyms instead of repeating the same word
• Vary sentence structure and transitions
• Replace common words with more specific alternatives
• Read your text aloud to identify repetition
