Readability Scorer
Estimate reading grade level from sentence and syllable length.
How hard is your writing to read?
Readability formulas estimate the education level needed to understand a passage by measuring two things: how long your sentences are and how many syllables your words have. This tool counts words, sentences, and syllables in what you paste and turns them into a grade-level score, so you can tell whether your copy reads like a newspaper or a legal contract.
Lower scores are easier: marketing and web copy usually aim around grade 7–8, while long sentences full of multi-syllable words push the score up fast.
Accuracy and privacy
Syllables are estimated by counting vowel groups, which is close but not perfect for unusual words, so treat the score as guidance rather than an exact grade. All analysis runs in your browser and your draft is never uploaded.
Frequently Asked Questions
What does the score mean?
It approximates the US school grade level needed to read the text easily. Around grade 7–8 is a common target for web and marketing copy.
How does it count syllables?
It estimates syllables by counting vowel groups in each word — accurate for most words but approximate for unusual spellings.
Is my draft private?
Yes. The text is analysed in your browser and never uploaded.
