Questions
- Which formulas do you use?
- Flesch-Kincaid Grade Level and Flesch Reading Ease — the same two schools and publishers use. They are computed in your browser, so nothing is sent anywhere to get a score.
- What makes a sentence hard?
- Four things get flagged: sentences over 25 words, words of four or more syllables, passive voice, and adverbs doing no work. Click any highlighted sentence to see which applies.
- Is checking really unlimited?
- Yes. Analysis costs us nothing to run, so it has no limit and no signup. Only AI rewriting is capped on the free plan.
