Flesch-Kincaid Readability & Grade Level Analyzer is a free web calculator for estimating reading ease and grade level. It uses sentence, word, and syllable counts to calculate Flesch reading ease and Flesch-Kincaid grade level. Results also show word, sentence, and estimated syllable counts, with a button to copy them. The calculator supports English and requires no account. Its syllable estimate counts vowel groups rather than checking a pronunciation dictionary, so words with silent vowels, unusual spellings, or non-standard pronunciations may be counted incorrectly. The formulas measure sentence length and syllable mechanics; they do not assess logical structure, jargon suitability, tone, or overall clarity. Veomark describes these scores as a quick, rough proxy and suggests shortening sentences and choosing shorter, more common words to improve them. Veomark says most tools run in the browser and core inputs are not uploaded to its servers. It also says Google Analytics 4 may set cookies or use similar technologies.
