You can record a note by asking r1 to transcribe something for you. For example, try saying "Record a note that John's birthday is April 23."
Your notes are saved to your rabbit account. To find one later, ask OS3 in conversation, for example "what notes did I take on my r1 this week?"
Tip: Press and hold the push-to-talk button and say "make a note…" to take a note. Be sure to hold down the button to record the entire voice session.
