Readability Score
Estimate how hard your text is to read, using sentence length, word length and Flesch-style readability metrics. Useful for checking that writing matches the audience it is meant for. It is free, needs no account, and adds no watermark to your result.

What happens to your file.
Sentences, words and syllables are counted and combined into Flesch-style readability measures, reported alongside the raw statistics so you can see what is driving the score. Sentence endings are recognised in other writing systems too, not only the full stop. This runs entirely in your browser.
Where it stops: These formulas measure sentence and word length, not clarity. Well-written technical writing scores as "difficult" simply because the terms are long, so treat the number as a prompt, not a verdict. Flesch counts syllables the way English spells them, so for a script without Latin vowels — Arabic, Chinese, Japanese — the reading-ease number is withheld rather than invented, and you get the word and sentence statistics instead.
Everything you need, without a paywall.
Common questions.
What score should I aim for?
Around 60–70 on the Flesch reading-ease scale suits general audiences. Official plain-language guidance often targets higher.
My technical writing scores badly. Is it wrong?
Not necessarily. The formula only counts word and sentence length, so accurate technical terms always score as "hard". Use it to spot long sentences, not to dumb down vocabulary.
Does it work in languages other than English?
For languages written in the Latin alphabet the syllable count handles accented letters properly, so Spanish, Turkish, Vietnamese and similar text is measured sensibly — though the Flesch scale itself was calibrated on English, so compare drafts against each other rather than against an absolute target. For Arabic, Chinese and other non-Latin scripts no score is reported, because the syllable rule does not apply.
