Free Readability Analyzer
Score a page with Flesch Reading Ease.
What is the Readability Analyzer?
The best-researched article in the world fails if people can't read it easily. Dense sentences and long words push readers away, raise bounce rates, and make even simple ideas feel like work — and search engines increasingly favor content that a wide audience can actually understand.
This readability analyzer fetches any page and scores its text with the industry-standard Flesch formulas, then shows the sentence and word patterns driving the score.
