Measure how easy your writing is to read with the industry-standard Flesch Reading Ease and Flesch-Kincaid Grade Level formulas — plus the sentence and syllable stats behind them.
A 0-100 score where higher is easier to read: 90+ is 5th-grade level, 60-70 is plain English (8th grade), 30-50 is college level, and below 30 is professional/academic. The formula weighs sentence length and syllables per word.
It converts the same inputs into a US school grade: a score of 8 means an 8th grader can read the text. Academic writing typically lands 12-16; marketing copy usually targets 6-9.
An approximate vowel-group counter — it strips non-letters and counts runs of vowels, with a correction for silent trailing 'e'. For most writing it matches dictionary counts within a few percent.
It depends on the assignment: persuasive and narrative essays usually land 50-70 (Flesch) / 8-11 (grade); research papers naturally sit 30-45 / 12-16. The goal is clarity, not a specific number.
