Who has an example of this tool being used on a site I can see?

Are you talking about the tool being Qualtrics? If so, it might be tricky to get examples from the community on a website. I know we do a lot of unusual things but they're all internal and note published on any pages. I recommend looking through the community to see neat tips and tricks users have shared. Outside of that, your best bet is to contact your Account Executive. They have access to all sorts of interesting case studies and can direct you to other resources.

Edited because I see you posted this in Website/App feedback section. Sorry about that, it popped on my 'Unanswered question' section. Carry on, never mind. 😀
