Readability Analysis Tool

The tool calculates four key metrics: Flesch Reading Ease (overall difficulty score 0-100), Flesch-Kincaid Grade Level (US school grade equivalent), Average Sentence Length (words per sentence), and Complex Word Percentage (words with 3 or more syllables). Together they give a complete picture of how accessible your writing is.

Both. It scores your original text, then generates a clearer rewrite and scores that too, so you see a before-and-after readability comparison. You can copy or edit the improved version and use it directly.

For academic writing, a Flesch Reading Ease score between 30 and 50 is typical and acceptable, since academic content uses technical vocabulary and complex structures. A Flesch-Kincaid Grade Level of 12-16 (college level) is appropriate. If your score is below 30, consider simplifying sentence structure even if the vocabulary must stay technical.

You can analyze up to 1,800 words per session. For longer documents, split the text into sections and analyze each part separately - this gives more useful feedback because you can pinpoint which sections are harder to read.

Shorten long sentences, break run-ons into two, replace long or technical words with simpler alternatives, cut filler phrases, and use active voice. The tool's recommendations and improved version show exactly which of these changes will raise your score the most.
