Readability Scorer
Scores your text with the classic readability formulas — Flesch Reading Ease, Flesch–Kincaid Grade, SMOG, Gunning fog, Coleman–Liau and ARI — shows the inputs each formula saw (sentence length, syllables per word) and translates the numbers into a school-grade estimate.

Notes
- Syllables are counted with a heuristic (vowel groups plus corrections), the same approach most tools use; expect small differences from hand counts.
- The formulas were calibrated on English prose. Scores for other languages, code or bullet lists are not meaningful.
