Nothing you enter leaves your device
All of the work happens inside your browser. Whatever you type is never packaged up and sent to a server, and no request this page makes carries it.
That makes it safe for contract amounts, personal details and internal documents you would rather not hand to a third party — close the tab and it is gone.
What this tool does not do
Readability Score Calculator only does what a browser can do on its own — it talks to no backend service. So it keeps no history for you and syncs nothing across devices; if you need a record, copy or download the result.
It is also not a substitute for professional judgement. For legal, medical or tax decisions, treat the output as a starting point rather than a final answer.
Frequently Asked Questions

- 60 to 70 is plain English that most adults read comfortably. Anything above 80 is easy enough for a middle-schooler.
- What do the grade levels mean?
- The Flesch-Kincaid grade level estimates the US school year needed to understand the text. Grade 8 is a good target for general audiences.
