Smith.ai review: the AI phone agent with real humans behind it
Answer in brief: Smith.ai's AI Receptionist is the best AI phone agent for small businesses that can't afford a botched call. It answers 24/7, qualifies leads and books appointments, and it can pass complex calls to live receptionists in North America around the clock. You can start on a free plan with 25 calls a month. Paid plans bill per call, from $150/month for 75 calls.
Top pick for AI answering with a human safety net. An established answering-service company built this AI-first receptionist, so a human can step in when it matters.

Every inbound call answered, day or night
Smith.ai picks up your business line 24/7. It answers questions, qualifies leads, schedules appointments with AI scheduling tools such as Calendly, and makes warm transfers. When a call needs judgment, it can hand off to live North America-based receptionists 24/7. That human escalation path is rare among AI phone agents. Smith.ai also sells hybrid and human-first plans if you want people to take the lead.
Voice and call quality you can rehearse
The AI answers in English and Spanish, and you can customize the voice. Quality Studio includes 50 simulated calls a month at no charge, so you can hear how the agent handles your real scenarios before customers do. Smith.ai doesn't publish latency figures.
Spam filtering that protects your quota
Smith.ai says it filters more than 20 million known spammers, and that up to 10% of calls can be removed as spam before they count against your plan. On a per-call plan, that directly lowers your bill.
