Readability Checker — free online tool
You write something, read it back, and it feels fine to you. But will a stranger get it on the first try, or stumble halfway through? It's hard to judge your own words. We added a free tool that checks it for you — Readability Checker — right in your browser.
What it does
Paste your text and it scores the readability right away. You get the Flesch Reading Ease number, the Flesch-Kincaid grade level, and a Gunning Fog estimate, so you can see at a glance whether your writing reads light and clear or heavy and dense.
Nothing leaves your device
The whole thing runs in your browser. Your text is never uploaded to a server and nothing is saved anywhere. When you close the tab, it's gone — so even a private draft or a work email is safe to check.
How to use it
- Open Readability Checker and paste your text into the box.
- Read the scores it shows you.
- Tweak the long sentences and big words, then check again until it reads easy.
It's free with no limit. There are more small tools on the Apps page.
