Calculates a text's readability using the Flesch Reading Ease formula for English, or the Fernández-Huerta formula for Spanish (a distinct adaptation, never presented as identical to the English one). Shows words, sentences, syllables, and the real score without rounding it into a fixed range. It never claims Google uses this score as a direct ranking factor, and never promises the reader will understand the text. Uses the same syllable-counting logic as the Syllable Counter.
Type or paste a text to calculate its readability.
Spanish text uses the Fernández-Huerta formula (not the same formula as English Flesch). Google doesn't use this score as a direct ranking factor, and the score never guarantees a reader will understand the text.
