Why Flesch Reading Ease?
The Flesch Reading Ease formula has been around since 1948 and is still the gold standard for measuring how easy text is to read. It looks at two things: how long your sentences are, and how many syllables your words have. Short sentences + simple words = high score. Dense paragraphs + jargon = low score. Most general web content should aim for a score between 60 and 70.

Privacy first.
OneClick Readability Audit runs entirely in your browser. It never sends your page content anywhere, never collects your data, and doesn't require any account or login. It reads the text on the page you're viewing and does all the math locally — that's it.
