Passive and adverb marks are heuristics. They miss some cases and flag a few that are not passive.
The formulas are for English. Sentence counts and highlights still apply.
Your text appears here with the marks you choose.

Questions
What do the Flesch scores mean?
Flesch Reading Ease runs from 0 to 100, and higher is easier. Below 30 is very hard, at college graduate level. 60 to 70 is plain English for most adults, and 90 and over is very easy, at about 5th grade. The bands follow the table published with Rudolf Flesch’s 1948 formula. The grade level uses the Flesch–Kincaid formula from a 1975 US Navy study.
How are syllables counted?
With a rule-based guess: each group of vowels is one syllable, with allowances for silent endings such as -e, -ed and -es. A list of common words the rules get wrong is fixed by hand. A count can be off by one for a word, so treat the score as an estimate.
Why are there no scores for my text?
The formulas were made for English. If the page is not in English, or the text has few Latin letters, the sentence counts and highlights still work, but no score is shown.
Is my text sent anywhere?
No. The checking runs in your browser, and nothing is stored after you close the tab.
