But you have to instruct Siri to record/transcribe/save what you want to say; this does it automatically. It removes friction if you just want to record short notes.

I almost never want to take a note though, I usually want to perform an action.

Recording a note isn’t high friction in my opinion though: “Hey siri make a note XYZ”. Admittedly I don’t create or use notes like this, but I use reminders a lot and I’ve never felt like there was friction: “hey siri remind me to call Dave when I get home”
