Frequently asked questions
What is a good score?
60 to 70 is plain language most adults read easily. Above 80 is very easy; below 30 is academic or legal prose.
How accurate is the syllable count?
It is estimated from vowel groups, which is accurate to a few percent on typical prose and enough for comparing drafts.
