Smith.ai vs Ruby (2026): AI vs human receptionists
By Sam Bigelow — Founder & Principal Strategist. 15 years inside Fortune 500 networking & global manufacturing.
Smith.ai is an AI receptionist billed per call — $150 to $800 a month on published tiers, with a free 25-call plan below (as of July 2026). Ruby is live human receptionists billed per minute — $250 to $1,725 a month for 50 to 500 minutes. AI is cheaper per conversation and answers everything instantly; Ruby's people win on warmth and judgment.
Smith.ai and Ruby are both well-known names in answering, but they're different products. The choice comes down to two questions: who picks up the phone — software or a person — and how you're billed for it, per call or per minute.
Smith.ai: an AI receptionist, billed per call
Smith.ai's AI Receptionist answers calls, qualifies, and books, with one standout feature: a trained human receptionist can take over when the AI escalates. As of July 2026 the self-setup Pro plans run $150, $270, and $500 a month for 75, 150, and 300 calls, with a free 25-call plan below and Enterprise plans at $500–$800 for 300–500 calls; extra calls bill at the tier's per-call rate of $1.50–$3.00, and no per-transfer fee is published for live-agent handoffs. The pricing is published, there's a genuinely free entry tier, and a 30-day money-back guarantee caps at $1,000.
Ruby: live human receptionists, billed per minute
Ruby is not AI — it's live, US-based receptionists who answer in your company's name, and it has been doing that since 2003. Pricing is built on the receptionist minute: $250 a month for 50 minutes, $395 for 100, $720 for 200, and $1,725 for 500 (as of July 2026). The catch most buyers skim past is what a minute includes — the clock covers hold time and after-call work, and calls round up to the next full minute, so a 40-second wrong number bills as one minute. Unused minutes don't roll over. Answering runs 24/7/365 with live transfer, and bilingual English/Spanish answering is included 24/7 at no extra cost — only outbound call assists are limited to weekday daytime hours, Pacific (as of July 2026).
Side by side
Where the same call is priced very differently — verified July 2026:
| Service | Pricing | Billing | Who answers | Best for |
|---|---|---|---|---|
| Smith.ai | Free (25 calls) to $150–$800/mo; extra calls $1.50–$3.00 | Per call; human escalation built in | AI, with human receptionists on standby | Steady volume wanting AI economics and a human backstop |
| Ruby | $250–$1,725/mo (50–500 minutes) | Per receptionist-minute, rounded up | Live human receptionists | Light, business-hours volume where a human voice is essential |
| Power2Network | $1,000 build + $499/mo (carrier at cost) | Flat — unlimited answering | AI workforce, run by a named human | High-value or seasonal calls; wants follow-up + reviews, not just answering |
The math that usually decides it
Per conversation, AI is far cheaper. Ruby's plans imply roughly $3.45 to $5.00 a receptionist-minute (as of July 2026), so a typical four-minute call runs about $14 to $20. Smith.ai prices the same call at well under that — an answered call works out to roughly $1.50 to $3.00 depending on tier. Double your call volume and Ruby's bill doubles with it; Smith.ai's rises in smaller, per-call steps, and a flat-rate service doesn't move at all.
Ruby earns its premium where empathy and judgment matter most — a distressed caller, an unusual situation, a high-end brand that needs a warm human voice. That's why some law firms and professional practices stay with it happily. The model simply gets expensive as volume climbs around the clock, which is the opposite shape of a trades phone.
The third option: flat-rate, no meter
If your phone rings hardest at night, on weekends, and in season, neither a per-call nor a per-minute meter is your friend. Power2Network is a managed AI workforce at $1,000 to build and $499 a month flat, with unlimited answering and carrier costs passed through at cost — the same bill in your busiest month as your slowest. It answers and books, then follows up, texts back missed calls, and requests reviews, all run by a named human. It costs more than a DIY tool, and at a handful of calls a week a $49–$79 DIY option — or Smith.ai's free 25-call plan — is the smarter buy; it's built for businesses where a missed call is a real job.
Frequently asked
Per conversation, considerably. Ruby's human plans imply about $3.45–$5.00 per receptionist-minute as of July 2026, so a four-minute call runs roughly $14–$20. Smith.ai's AI prices the same call at roughly $1.50–$3.00 depending on tier — and its free 25-call plan prices it at zero for very light phones. Ruby's strength isn't price — it's a warm human voice on every call.
