About the Readability Checker
Use this free Readability Checker to measure reading ease, grade level, sentence length, and content clarity directly in your browser.
Make content easier to understand.
The Readability Checker reviews how easy your writing is to read. It is useful for blog posts, academic drafts, landing pages, support content, emails, and any page where clarity matters.
Use the score as a practical editing signal. A lower grade level is not always better, but confusing sentences, dense paragraphs, and unnecessary jargon usually reduce performance.
How to use the Readability Checker
Add the content you want to review into the checker.
Look at Flesch Reading Ease, grade level, word count, sentence count, and syllable estimates.
If the score is too difficult for your audience, look for long sentences and complex phrasing.
Split long ideas, use clearer words, and keep paragraphs short enough to scan.
