Being a virtual personal assistant, of course Siri can take a note! In fact, Siri can not only take a note, but update them as well. If you need something that's more permanent than a reminder, something more like an idea you don't want to forget, or a draft you want to get down while you're driving, Siri and the Notes app are the perfect combination.
You can use to find notes store in the Notes app. Siri can either list all your notes, or you can ask Siri to search based on date or keywords in the contents of the note.
If all you want to do is quickly jot down an idea, memo, draft, or just a long string of text, Siri can do that for you.
If you want to keep adding to the same note, and you haven't done anything else with Siri since creating the note, just say "Add" followed by what you want to add.
Siri can also update older notes. This comes in handy if you have separate notes for separate types of material, or if an idea occurs to you long after you dictated the original note.
If you still need help with setting up or using Siri with your iPhone Calendar, or any other Siri feature, head on over to our Siri Forum and ask away!
