Readability Checker

Good call being upfront that syllables are counted by rule and the formulas fit English only. Flagging the longest sentences is the most actionable part for me. Any plans to highlight passive voice or very long paragraphs too, so it points at what to rewrite and not just the score?

I like that it runs in the browser and picks out the longest sentences, which makes simplifying service page copy much easier. Would you consider adding a target reading age, so you can see at a glance whether a page is pitched at the right level for customers?
