I noticed it when a student I'm mentoring emailed me to confirm our appointment and there were choices at the bottom that were relevant. I thought she did something to set up the survey. Then I noticed that on many mails.
It's pretty accurate so far too. I've never used a canned reply like this out of the box. But it has saved me typing as I choose a smart reply and then add to it.
Has anyone else had any good/bad experiences with smart reply?
