AI understands.
Real systems act.
Vesper is not a generic chatbot guessing answers. It is a quiet engineering pipeline: language models decode what your customer wants, but real database code checks and locks your actual calendar.
Customer sends a message across WhatsApp, Instagram, or Messenger at any hour.
Messages stream in through official Meta Cloud webhooks with sub-100ms response times. No unread notifications sitting till morning.
Quiet, instant, and accurate.

Confirmed: You are booked with Anita for Sunday at 3:00 PM. Calendar invite sent, see you then!
