🔍 Rational Design & Best Practices

AI Personalization Boosts Follow-Through
Personalized messages and human-sounding voice notes significantly increase user engagement and trust.

Email + calendar + SMS ensures the user receives the booking details via their preferred method.

AI Agents for Edge Cases
Agents are used for formatting and natural-language generation to make the system flexible and future-proof.

Clients simply fill out a form — the rest is handled with high-quality automation.

Fully Extensible
Swap in different voice APIs, CRMs, or calendar providers with minimal changes to the core logic.
