Readability Formulas
Readability Formulas offers tools to score English text and estimate the grade level and age of readers likely to understand it. Its Readability Scoring System includes formulas such as Flesch Reading Ease, Flesch-Kincaid, Gunning Fog, SMOG, Dale-Chall, Spache, FORCAST, Fry and Raygor. Text can be pasted or supplied as .txt, .docx, .rtf, .html or .pdf files. Text Statistics reports measures including syllable count, average sentence length, abbreviations, proper nouns and passive voice. The beta Robert Gunning Editor helps locate difficult words and wordiness, with editing tools for phrases, nominalizations, fuzzy words and weak verbs. Batch Processing, also in beta, scores multiple texts with one or more formulas. A Chrome and Microsoft Edge extension can score highlighted web text, open the editor and show word statistics. The privacy policy says processing runs through local browser scripts and submitted text is not stored on a server or accessible to the site. The Synonym Finder connects to Datamuse and may transmit one word at a time.
