Readability Checker
Paste in an abstract, chapter, or full manuscript and watch your Flesch Reading Ease score and Flesch-Kincaid Grade Level update live, so you can see exactly how accessible your sentence structure and word choice really are.
What counts as a good score?
Most scholarly writing falls between “Fairly Difficult” and “Difficult” (Flesch Reading Ease 30-59) -- that’s expected for academic work, not something to chase away.
Sentence length drives the score
Long sentences packed with multi-syllable words push both metrics toward “more difficult.” Splitting one long sentence often helps more than swapping vocabulary.
