Is your content readable and quotable?
Paste any text. Get Flesch reading ease, grade level, average sentence length, passive voice and the long sentences to fix. Plus an answer-readiness score for how easily ChatGPT and Perplexity can lift a direct answer from it.
Paste at least one sentence to see the scores.
How it works
The checker splits your text into sentences and words, counts syllables with an English rule set, and computes Flesch Reading Ease, Flesch–Kincaid Grade, Gunning Fog and SMOG. Passive voice is a heuristic (a form of "to be" followed by a past participle), so treat it as a pointer, not a verdict. The answer-readiness score is our own: it rewards a direct opening sentence, short sentences, low passive voice and concrete numbers, the traits we see in passages ChatGPT and Perplexity quote.
Why this matters for citations is covered in E-E-A-T and answer engine optimisation and on our AEO service page.
Readability Checker: common questions
What Flesch reading ease score should I aim for?
60 to 70 for a general audience, which is roughly grade 8 to 9. Service business pages that score under 50 are read like legal text, and both people and AI engines skip them.
What is the answer-readiness score?
Our own heuristic for how quotable a passage is: does it open with a direct statement, are sentences under 25 words, are there numbers or specifics, and is passive voice low. AI engines favour passages with those traits when choosing what to cite.
Does readability affect SEO?
Not as a direct ranking factor, but readable pages hold attention longer and get quoted by answer engines more often. Google's helpful content guidance also rewards clear, direct writing.
