Smith.ai is a hybrid answering service that combines AI technology with live human receptionists. Founded in 2015, they've built a reputation as a reliable answering service for small businesses, particularly law firms and home service companies.
How Smith.ai Works
Smith.ai uses a two-tier approach:

- Human backup when needed: If the AI can't handle it, the call transfers to a live human receptionist
- Message relay: Information is sent to you via email, text, or CRM integration
