But mom doesn't title it recipe, that's an afterthought... it's How are you and the kids and I've got ten others as well so siri does the work... I light a cigar outside, flip the phone, ask about the recipe and siri says yea or nay and I'm done... that's the idea behind it... no checking, reading looking at notifications... a one-handed swipe and statement and use or forget depending on answer...
How effective is another question but it's a great idea and better than notifications etc which require interventions/actions apart from the most basic... no need to even open any email app just ask...
