I see that fellow users have been asking for Apple Keynote integration from Mentimeter since at least 2020. We're going on SIX years without word on Keynote integration. I'm testing Mentimeter for a large community college district (74k students) and heavily rely on Keynote for my photojournalism class presentations. I've found that PollEverywhere DOES have a Keynote integration so I will try them out. If Mentimeter does not integrate with Keynote, I will have to vote "no" to our testing team purchasing Mentimeter for our district and instead propose alternatives.
