Readability analyzer

Paste text; words, sentences, syllables, average sentence length, Flesch Reading Ease (EN) or Ateşman (TR), and the most frequent words.

How to read it

Ateşman (TR): 198,825 − 40,175 × (syllables/word) − 2,610 × (words/sentence). 90+ very easy, 70–89 easy, 50–69 medium, 30–49 hard, <30 very hard. Turkish syllables equal the vowel count.
Flesch Reading Ease (EN): 206,835 − 1,015 × (words/sentence) − 84,6 × (syllables/word). 60–70 plain English for a general reader; 30'un altı academic.
For web copy keep the average sentence at 15–20 words; split sentences of 30+ words.
The frequent-word list removes a short TR+EN stop-word list; it shows what the text is really about.
