Methods and limits
English prose only. Uses Flesch Reading Ease and Flesch–Kincaid grade formulas with heuristic vowel-group syllable counts and punctuation-based sentence splitting. Abbreviations, specialist words and short samples affect estimates. Scores may fall outside 0–100 and do not measure comprehension or writing quality. Reading time uses the chosen words-per-minute assumption.
