FAQ

Paste text or a page URL and click analyze. You get six indices (Flesch Reading Ease, Flesch-Kincaid, Gunning Fog, SMOG, Coleman-Liau, ARI), average sentence length and word statistics. No sign-up; the limit is 25 requests per minute.

Flesch Reading Ease is a number from roughly 0 to 100: the higher it is, the easier the text. 60–70 counts as plain language, below 30 as very difficult. It depends on average sentence length and syllables per word.

Partly. The formulas were designed for English. For Russian we show a Flesch adaptation (Oborneva) and approximate values for the other indices. Use them to compare versions of one text, not as an absolute rating.

It is a notional US school grade needed to understand the text easily. A value of 8 means an eighth-grader's level. Mass audiences are usually targeted at 6–9, while specialists can take more.

Shorten long sentences, replace rare words with simple ones, split paragraphs and use lists. After the edits run the check again and compare the indices and the average sentence length.

Yes, enter its address instead of text: the tool extracts the page text and computes the indices. If the page is built by JavaScript or closed to bots, the text cannot be retrieved.

Dónde somos más débiles: the formulas are tuned for English, syllables are counted approximately, and there is no highlighting of hard sentences, file upload or rewriting advice.

Cuándo elegir PromoPilot: When you want to judge in a second how hard a text is and compare several versions with familiar indices, including for a page by its address. For sentence-by-sentence rewriting advice you need an editor such as Hemingway.

¿Por qué analizar la legibilidad?

La legibilidad influye directamente en la interacción de la audiencia, el tiempo en el sitio y las conversiones. El nivel óptimo para contenido web es el grado 7-8 en la escala Flesch-Kincaid. El análisis también revela burocratismos, repeticiones y otros indicadores de contenido generado por máquinas.
