Stellar vs Smith.ai: Full AI Automation vs Human-Backed Answering
Smith.ai built its reputation on live virtual receptionists and now layers AI on top of that human team. The result is high-touch inbound answering, lead intake, and appointment booking, with humans available to take over when the AI hits something complex. That quality comes at a premium, and the per-call pricing model means your bill scales directly with how busy you get. Stellar takes the opposite approach: a no-code AI platform that handles inbound booking and support plus outbound lead qualification and event confirmation, on a subscription with per-minute overage instead of per-call fees. There are no humans in the loop, which keeps costs flat and predictable as you scale.
The verdict
Smith.ai is the safe pick if you want real humans answering complex calls and you make a low, steady volume of them. Stellar is the better fit if you want to automate end to end, run outbound campaigns, and keep a predictable bill as call volume grows.
Where Stellar wins
- Outbound and inbound. Stellar qualifies leads, confirms appointments, and books calls. Smith.ai focuses on inbound answering and intake.
- Predictable subscription with per-minute overage, not per-call fees that balloon during busy periods.
- Built-in TCPA compliance (DNC, consent, calling windows) for the outbound calls Smith.ai does not make.
- Knowledge base with vector search so the agent answers from your docs, plus a contact CRM and full call analytics.
- No-code builder and self-serve setup. Live in under 30 minutes with no onboarding call.
Where Smith.ai wins
- Live human receptionists take over complex or sensitive calls that AI should not handle alone.
- Established brand with a long track record in legal, professional services, and SMB answering.
- Done-for-you setup and managed call handling for teams that prefer a hands-off service.
Pricing compared
Smith.ai charges per call. Its AI Receptionist starts around $97.50/mo, and the hybrid human plans begin near $292/mo for 30 calls, with overage calls running roughly $9 to $10 each. That model is fine at low, predictable volume, but the bill rises every time call volume spikes. Stellar uses a subscription plus per-minute overage: a 14-day free trial, then Growth at $149/mo (200 minutes included, $0.18/min overage), Pro at $399/mo (750 minutes, $0.14/min), and Scale at $899/mo (3,000 minutes, $0.11/min). For higher call volumes, per-minute pricing is usually far cheaper than per-call.
Switching from Smith.ai
Moving from Smith.ai means shifting from a managed answering service to a self-serve platform you control. Rebuild your call flows in Stellar's templates, connect your calendar and CRM, and you are live. Your phone numbers stay portable. Most businesses are running in an afternoon.

Does Stellar use human receptionists like Smith.ai?
No. Stellar is fully automated AI. Smith.ai's differentiator is that live humans can take over complex calls. If having a human in the loop is a hard requirement, Smith.ai fits that. If you want consistent, around-the-clock automation without per-call human costs, Stellar is built for that.
Is Stellar cheaper than Smith.ai?
It depends on volume. Smith.ai's per-call pricing can be lower if you take very few calls per month. As call volume grows, Stellar's per-minute subscription is usually more cost-effective and far more predictable, since you are not paying a flat fee for every single call.
Can Stellar make outbound calls?
Yes. Stellar qualifies leads, confirms appointments, and runs multi-touch outbound campaigns. Smith.ai is focused on inbound answering and intake, so outbound is a capability Stellar adds that Smith.ai does not offer.
Does Stellar book appointments?
Yes. Stellar books directly into Google Calendar, Cal.com, or Calendly in real time during the call, the same core capability Smith.ai offers, handled entirely by AI.
