Flesch-Kincaid Readability & Grade Level Analyzer
What it is
Flesch-Kincaid Readability & Grade Level Analyzer is a free web calculator from Veomark for estimating how difficult English text may be to read. It calculates Flesch reading ease and Flesch-Kincaid grade level from sentence, word, and syllable counts. Results also show word count, sentence count, and estimated syllable count, with a button for copying the output. The calculator offers sentence analysis and clarity recommendations without requiring an account. Its syllable method counts groups of vowels instead of consulting a pronunciation dictionary, so silent vowels, unusual spellings, and non-standard pronunciations can affect results. The formulas address sentence length and syllable mechanics, not logical structure, jargon, tone, or overall clarity. Veomark describes the scores as a quick, rough proxy and suggests shorter sentences and more common words when improving readability. Most tools run in the browser, and Veomark says core inputs are not uploaded. Google Analytics 4 may set cookies or similar technologies.
