Free Content Readability Checker

Flesch Reading Ease Score

Get an instant readability score using the Flesch Reading Ease formula. Know whether your content is easy, standard, or difficult to read.

Match Your Audience

Different audiences need different reading levels. Blog posts should be 60-70 (standard). Technical docs can be lower. Marketing copy should be 70+ (easy).

Readability Is an AI Ranking Signal

AI engines quote text they can parse cleanly — short sentences, one idea per paragraph, concrete numbers. If your content scores as difficult, both human readers and language models skim past it. Aim for short declarative sentences and answer-first paragraphs, then re-check the score until it lands in your audience's band.
