[Sigia-l] Readability tool & "click on radiobutton"

[Peter VanDijck]

Hi all,
I am producing content for a 4th grade reading level. Someone told me
there existed tools to check readability. One person even mentioned Word
had such a tool. I searched online but all I found where calculations
where you had to count words yourself.

Does there exist a tool where you can just paste in a piece of text and
it will estimate reading level for you?

On a related level: how do you say "click on the radiobutton next to the
name" to people who don't know what a radiobutton is? Any resources for
these types of issues?

Thanks,
