Check Readability vs Flesch-Kincaid Readability & Grade Level Analyzer

Check Readability analyzes pasted text and returns nine readability scores alongside a consensus grade level. The formulas include Automated Readability Index, Flesch Reading Ease, Gunning Fog, Flesch-Kincaid Grade Level, Coleman-Liau, SMOG, LINSEAR Write, FORCAST and New Dale-Chall. The web analyzer gives feedback on complexity, sentence length and word choice. A Chrome extension adds a native Side Panel, full-page or selected-text extraction and interactive formula breakdowns; scoring happens locally without transmitting page content or selected text. Text submitted to the website is sent over an encrypted connection and kept in memory only while scores are calculated. The site says analyzed text is not logged or stored, while Google Analytics is used for page visits and browser-related information. Check Readability is free, requires no account and permits personal and commercial use. The product says readable content can support accessibility and search rankings. Its scores are statistical estimates and cannot determine whether writing is accurate, logical, appropriate or well argued. The extension supports System, Light and Dark interface modes.

Flesch-Kincaid Readability & Grade Level Analyzer is a free web calculator for estimating how readable English text may be. It calculates Flesch reading ease and Flesch-Kincaid grade level from sentence, word, and syllable counts. Results include both scores alongside the word, sentence, and estimated syllable counts, with a button to copy them. The page also offers sentence analysis and clarity recommendations, framing its scores as a quick, rough proxy and suggesting shorter sentences and more common words as ways to improve them.

Syllables are estimated by counting vowel groups rather than looking up pronunciations, so silent vowels, unusual spellings, and non-standard pronunciations can throw off the count. The formulas address sentence length and syllable mechanics; they do not assess logic, jargon, tone, or overall clarity. No account is required.
