Smith.ai vs Ruby Receptionists: Pricing, Features and the Call-vs-Minute Trap
Smith.ai vs Ruby Receptionists: Pricing, Features and the Call-vs-Minute Trap
Smith.ai and Ruby Receptionists look like direct competitors, but their prices are measured in different units, and that is the trap in this comparison. Smith.ai’s AI Receptionist charges per call, while Ruby charges per minute, so a headline price comparison without converting units will mislead you. At a 100-call month with three-minute average calls, Smith.ai’s AI Pro costs about $212.50 before add-ons, while Ruby’s 200-minute plan at $720 plus overage for the extra 100 minutes lands between $1,050 and $1,260. The two products are not in the same price league once units are converted, and the right pick depends on whether you want AI speed with a human escalation path or a fully human receptionist team.
Key takeaways
- Smith.ai meters calls. Ruby meters minutes. Any comparison that skips the conversion is wrong.
- Smith.ai AI Receptionist: free 25-call plan, Pro from $150 for 75 calls, Enterprise from $500 for 300 calls, overage $2.10 to $3.00 per call.
- Ruby Receptionists: 50 minutes for $250, 100 for $395, 200 for $720, 500 for $1,725, overage $3.30 to $5.40 per minute by tier.
- G2 users rate Smith.ai Virtual Receptionists 4.9 out of 5 from 73 reviews and Ruby 3.8 out of 5 from 12 reviews. Trustpilot rates Smith.ai 4.3 out of 5 from 375 reviews.
- Smith.ai offers a human escalation path behind its AI. Ruby is a fully human service with no AI tier.
What is the call-vs-minute trap?
The trap is simple: a call is not a minute. Smith.ai sells you a number of calls, however long each one runs. Ruby sells you a number of minutes, however many calls those minutes cover. A 100-call month at an average of three minutes per call is 300 minutes of talk time. On Smith.ai AI Pro, that month costs $150 for 75 included calls plus 25 extra calls at $2.50, or $212.50 before add-ons. On Ruby, 300 minutes needs the 200-minute plan at $720 plus 100 minutes of overage at the plan’s per-minute rate, which falls in the $3.30 to $5.40 range, giving $1,050 to $1,260. The gap is not a rounding difference. It is the difference between an AI product and a human product, and buyers who compare $150 against $395 without converting are comparing a per-call price against a per-minute price as if they were the same thing.
That conversion cuts both ways. If your calls are long, say eight minutes of intake for a law firm, Ruby’s minute meter punishes you harder than Smith.ai’s call meter, because one long call costs Ruby eight minutes and Smith.ai one call. If your calls are short, under a minute each, Ruby’s minute meter is kinder than it looks, because 100 short calls might use only 60 minutes. Count your average call length before you compare anything else in this post.
How do Smith.ai and Ruby prices compare?
Smith.ai sells two products with two price lists, and this comparison uses the AI Receptionist as the main table, with the live human plans as a clearly labelled contrast. Ruby sells one product: human receptionists, priced by minute.
| Smith.ai AI Receptionist | Price | Included | Overage |
|---|---|---|---|
| Free | $0 a month | 25 calls | $3.00 per extra call |
| Pro | From $150 a month | 75 calls, blocks to 300 | $2.10 to $3.00 per extra call |
| Enterprise | From $500 a month | 300 calls, blocks to 1,000 plus | About $1.60 to $1.67 per extra call |
| Ruby Receptionists | Price | Included | Overage |
|---|---|---|---|
| 50-minute plan | $250 a month | 50 minutes | $3.30 to $5.40 per minute by tier |
| 100-minute plan | $395 a month | 100 minutes | $3.30 to $5.40 per minute by tier |
| 200-minute plan | $720 a month | 200 minutes | $3.30 to $5.40 per minute by tier |
| 500-minute plan | $1,725 a month | 500 minutes | $3.30 to $5.40 per minute by tier |

Ruby rounds minutes to 60 seconds and offers no trial, but a 21-day money-back guarantee, plus a chat add-on at $114.40 bundled or $143 standalone for 10 chats.
What do reviewers say about each?
Reviewers rate Smith.ai higher than Ruby on both major platforms, but the samples differ in size and the products differ in kind. G2 rates Smith.ai Virtual Receptionists 4.9 out of 5 from 73 reviews and Ruby Receptionists 3.8 out of 5 from 12 reviews. Trustpilot rates Smith.ai 4.3 out of 5 from 375 reviews. Ruby’s smaller G2 sample means its 3.8 is less stable than Smith.ai’s 4.9, but the direction is consistent: reviewers praise Smith.ai for professionalism, detailed call summaries, and transparent pricing, and several report switching from Ruby to Smith.ai for lower cost and clearer billing. Ruby reviewers praise responsive support staff and a high answer rate, while complaining that Ruby is one of the more expensive options with unclear billing and price increases.
One complaint theme deserves attention on Smith.ai’s side: billing mechanics around cancellation and transfers to paid human agents. Chronexa’s 2026 review of Smith.ai’s Trustpilot record found about eight of the twenty one- and two-star reviews concerned cancelling, refunds, or billing after trying to leave, plus cases of calls transferred to paid human agents without the owner agreeing. That is the contract question to settle before signing: who can transfer a call to a paid human, and does it cost extra? Smith.ai’s AI can escalate to live human receptionists, which is the category’s rare AI-plus-human model, but some live-agent involvement is an add-on, so do not assume every human transfer is included.
What does the human comparison look like?
If you want humans on every call, the comparison shifts to Smith.ai’s live Virtual Receptionist plans against Ruby. Smith.ai live plans run $300 a month for 30 calls on Starter, $810 for 90 calls on Basic, and $2,100 for 300 calls on Pro, with 10 percent off on a 12-month subscription and overage from $8.50 to $11.50 per call. Ruby’s 100-minute plan at $395 covers roughly 33 three-minute calls. A 90-call month at three minutes each is 270 minutes: Ruby needs the 200-minute plan at $720 plus 70 minutes of overage, while Smith.ai Basic at $810 covers the 90 calls outright. At that volume the human options are close in price, and the choice turns on service details rather than the bill. Ruby includes bilingual answering and a well-known brand; Smith.ai includes spam-call exclusion from billing and the AI front end for after-hours overflow.
Who should pick Smith.ai, and who should pick Ruby?
Pick Smith.ai’s AI Receptionist if your volume is high in calls but moderate in minutes, if you want a free 25-call tier to test with, or if you want AI speed with a human escalation path for complex calls. It fits law firms and professional services that need structured intake, and it fits any business where long calls would make a minute meter expensive. Pick Smith.ai’s live plans if you want humans but like Smith.ai’s billing, including spam exclusion.
Pick Ruby if you want a fully human team on every call, if your calls are short enough that the minute meter works in your favour, or if you value Ruby’s support reputation and are willing to pay the premium. Ruby is the more expensive option in most volume scenarios in this post, and buyers should go in knowing that. If neither fits, start from Best AI Receptionist for Small Business in 2026 or compare the two vendors’ own review posts: Smith AI Reviews and Ruby Receptionists Reviews.
Frequently asked questions
Is Smith.ai cheaper than Ruby Receptionists?
Smith.ai’s AI Receptionist is much cheaper than Ruby at most volumes, because it charges per call while Ruby charges per minute. A 100-call month at three minutes per call costs about $212.50 on Smith.ai AI Pro before add-ons, versus $1,050 to $1,260 on Ruby. Smith.ai’s live human plans are priced closer to Ruby.
Does Smith.ai charge per call or per minute?
Smith.ai’s AI Receptionist charges per call: free for 25 calls, Pro from $150 for 75 calls, Enterprise from $500 for 300 calls. Its live Virtual Receptionist plans also charge per call. Ruby charges per minute, which is why the two price lists cannot be compared without converting calls to minutes.
What is Smith.ai rated on G2 and Trustpilot?
G2 rates Smith.ai Virtual Receptionists 4.9 out of 5 from 73 reviews, and Trustpilot rates Smith.ai 4.3 out of 5 from 375 reviews. Ruby rates 3.8 out of 5 from 12 G2 reviews. Ruby’s smaller sample makes its score less stable than Smith.ai’s.
Does Ruby Receptionists offer a free trial?
No. Ruby offers no trial, but a 21-day money-back guarantee. Ruby rounds minutes to 60 seconds, and its chat add-on costs $114.40 bundled or $143 standalone for 10 chats.
Can Smith.ai transfer calls to a human?
Yes. Smith.ai’s AI can escalate to its live human receptionists, which is rare in this category. Some live-agent involvement is an add-on, so confirm before signing who can trigger a transfer and whether it costs extra.
Which is better for a law firm, Smith.ai or Ruby?
Smith.ai usually fits law firms better, because long intake calls cost one call on Smith.ai but many minutes on Ruby, and Smith.ai’s intake, conflict checks, and booking add-ons are built for legal workflows. Ruby fits firms that want a fully human team on every call and accept the premium price.
