This checker scores your copy with four standard readability formulas, then translates the number into one plain answer: can a normal customer read this fast and trust it? Paste any page above and find out in real time. Nothing is uploaded, everything runs in your browser.
Flesch Reading Ease runs 0 to 100, and higher is easier (60 to 70 is comfortable plain English). Flesch-Kincaid Grade Level turns that into a U.S. school grade, so a 7 means a 7th grader can follow it. Gunning Fog and the SMOG Index both estimate the years of schooling a reader needs, and they lean harder on long, multi-syllable words. When all four point at the same range, you can trust the read.
Every one of these indices comes down to three things: how many words, how many sentences, and how many syllables. The tool counts your words and sentences directly, then estimates syllables with a vowel-group heuristic (it groups adjacent vowels, trims silent endings like a trailing "e", and applies a few common adjustments). It then plugs those counts into the published Flesch, Flesch-Kincaid, Gunning Fog, and SMOG formulas. Syllable counting is an estimate, so treat the grade as a tight range rather than a single exact number.
The average American reads most comfortably at around a 7th to 8th grade level, and people read marketing on their phone even faster and lazier than that. Writing at grade 11 does not make you look smart, it makes you look hard to deal with. Plain copy also helps you in AI search: ChatGPT and Google AI Overviews summarize and quote short, clear sentences far more reliably than dense ones, so the same simplification that converts homeowners also gets you cited.
Hemingway is free for basic highlighting but charges roughly 25 to 30 dollars a month for its AI rewrites. Grammarly gates tone and rewrite suggestions behind Premium. Originality.ai locks readability scoring inside a 14.95 dollar plan. This tool is unlimited, needs no signup, shows you four indices at once instead of one, and adds a homeowner-readability verdict the others do not. It will not rewrite your copy for you, that is the one thing the paid plans add, and it is exactly what our Pro version handles.
The Pro version rewrites your service pages into plain, persuasive, AI-friendly language that homeowners and search engines both prefer.
