Get Siri to Remind You About What You’re Looking At Right Now
1 Load a web page, article, email, or something similar onto the iOS screen that you wish to be reminded about
2 Summon Siri as usual by holding down the Home button (or using Hey Siri if you have the hands-free feature enabled)
3 Tell Siri “Remind me about this (when) at (time)”
4 Siri will confirm to remind you about the item or event, if the reminder is about a webpage, the webpage will be saved as the article, if it’s about an email, the email will be saved as the reminder, etc
That’s it, the reminder will be set as usual.
