Tools for measuring copy simplicity

Hi all,

I’d be interested to hear about any tools people have used to measure their copy’s simplicity. I have a readable.com membership and it gives you a few different measurements, but I don’t know which of those measurements is worth paying attention to more than others.

It’d also be interesting to hear about how copy tools help within projects - for example, is the measurement something stakeholders care about? Maybe they even focus on it too much?

Any lived experience would be super helpful!

We use Siteimprove to report on reading age at nsw.gov.au after content is published. It’s a metric that is part of the nsw.gov.au measurement strategy. During writing, a few of us have used hemingwayapp.com.
