Readability Analyzer
Check how easy your writing is to read. Paste text to get its Flesch Reading Ease score, grade level, and a full count of words, sentences, and syllables.
How to use it
Paste or type your text into the box. The analyzer counts the words, sentences, and syllables as you type and turns those counts into readability scores in real time — there is no button to press and nothing to submit. The headline number is the Flesch Reading Ease score, a 0 to 100 scale where higher means easier. It is driven by just two things: how long your sentences are on average, and how many syllables your words carry on average. Short sentences built from short, common words push the score up; long sentences packed with long words pull it down. A breezy blog post might land near 70, while a dense legal clause can fall below 30. Alongside it, the Flesch–Kincaid Grade Level translates those same two inputs into a U.S. school grade. A grade level of 8 means a typical eighth grader could follow the text on a first read. It is the more intuitive number when you have a specific audience in mind, because you can aim for a grade and check whether your draft hits it. Use the scores as a steering wheel, not a verdict. If a passage reads harder than you want, the fixes are always the same: break long sentences in two, swap a three-syllable word for a plainer one, and split a wall-of-text paragraph into shorter ones. Re-run the numbers and watch them move as you edit. Everything is computed locally in your browser, so the text you paste is never uploaded. That makes the analyzer a safe, quick check for blog drafts, marketing copy, product documentation, school essays, or any writing that needs to land clearly with its reader.
Frequently asked questions
- What is a good Flesch Reading Ease score?
- Higher is easier. 90–100 is very easy (5th grade), 60–70 is plain English for most adults, and below 30 is very difficult (college level). Aim for 60+ for a general audience.
- How are syllables counted?
- With a vowel-group heuristic that adjusts for a silent ending e — fast and good for scoring, but an estimate rather than a dictionary lookup, so unusual words may be slightly off.
- Is my text sent anywhere?
- No. The analysis runs entirely in your browser; nothing is uploaded.
- Which reading level should I aim for?
- For a general online audience, aim for a Flesch Reading Ease of roughly 60 to 70 — about an 8th- to 9th-grade level, the range most mainstream publications target. Technical or academic writing naturally scores lower, and that is perfectly fine for a specialist reader. The goal is to match the score to who you are writing for, not to maximize it blindly.
