FAQ
?What is a good readability score?
For most web content, a Flesch Reading Ease score between 60 and 70 is ideal, as it is easily understood by an average 13- to 15-year-old.
?How are complex words defined?
Our algorithm classifies complex words as those with three or more syllables, which often make text harder to digest for general audiences.
?Does this support languages other than English?
The current implementation is optimized for English, as formulas like Flesch-Kincaid and Gunning Fog are specifically designed for English sentence structures and syllable counts.
