Two steps in Muse. Nothing to install.

Ask for your first call

Ask Muse in your own words. The first time, it asks two quick questions: how the assistant introduces itself, and a phone number it may give out.

Call Sushi Ko and book a table for two this Friday at 7pm.

Call my dentist and move my appointment to any afternoon next week.
