How do I use Readability Score?

Fetch any URL and calculate Flesch Reading Ease (0–100) and Flesch-Kincaid Grade Level scores for its main content. Strips navigation and boilerplate so analysis focuses on the actual body text. Shows word count, sentence count, syllable count, and average words per sentence alongside the scores. A score of 60–70 is ideal for general web audiences. Higher scores mean easier reading.
