Smith.ai vs Ruby vs PhiClaw: Which Receptionist for a Medical Practice?

Smith.ai and Ruby are two of the best-known virtual receptionist services in the U.S. Both answer your business line so callers reach a person instead of voicemail. For a medical practice, though, the real questions are different: can they book into your EHR, will they sign a Business Associate Agreement, and what does it cost when the phones get busy?

Smith.ai in one paragraph

Smith.ai mixes AI and live agents. Its AI receptionist plans start around $95 to $150 a month (one October 2026 snapshot lists $150 for 75 AI-answered calls), and live-agent plans start around $300 a month for about 30 calls. You pay per call, and extras such as appointment booking can add per-call fees. Good for businesses that want a human backup on tricky calls.

Ruby in one paragraph

Ruby is human-first: live, U.S.-based receptionists, billed by the minute rather than by the call. Public pricing runs about $235 to $250 a month for 50 receptionist minutes. Reviewers praise the warmth of the calls; the trade-off is cost, because a three-minute average call means roughly 17 calls for that price.

Head to head

• Who answers: Smith.ai is AI plus humans. Ruby is humans. PhiClaw is AI that hands off to your staff when needed.
• Pricing unit: Smith.ai per call, Ruby per minute, PhiClaw $0.19 per minute on top of a $50/month local number.
• Booking into your EHR: answering services usually take a message or book into a scheduling tool. PhiClaw books, reschedules, and confirms directly in your EHR.
• Beyond the phone: Smith.ai and Ruby answer calls (and some chat). PhiClaw also texts patients back, runs intake, scribes, e-prescribes, bills, and faxes.
• HIPAA: both services market to healthcare. Before any patient calls, ask each for a signed BAA covering the exact plan you buy. PhiClaw signs a BAA on every plan.

What HIPAA actually requires

Under HIPAA, a medical practice can only hand protected health information (PHI) to a vendor that has signed a Business Associate Agreement (BAA). A BAA is the contract where the vendor promises to protect PHI, report breaches, and accept HIPAA obligations. Two details trip practices up: the BAA has to cover the exact product and plan you use, and it does not make you compliant by itself. You still need the right settings, access controls, and staff habits.

What PhiClaw does differently

PhiClaw is not an answering service. It is a HIPAA AI employee that answers the phone 24/7 and then actually does the work: books the visit in your EHR, verifies insurance, sends the intake form, and follows up on no-shows. It answers 83% of patient messages in under 60 seconds. The AI receptionist is $50 a month plus $0.19 a minute, as an add-on to the PhiClaw AI employee ($1,500 a month flat (4,320 questions/tasks included, unlimited users and locations, month-to-month), with a BAA on every plan).

When Smith.ai or Ruby is the right call

If your callers strongly prefer a human voice, your call volume is low, and someone in the office handles scheduling afterwards, a live service like Ruby or Smith.ai is a reasonable fit. If the goal is fewer missed calls and less work for the front desk, an AI that books and follows up will save more hours.

Frequently asked questions

Is Smith.ai or Ruby cheaper?

It depends on call length. Smith.ai bills per call and Ruby bills per minute (about $235 to $250 for 50 minutes). Short calls favor Ruby's math less; long calls favor Smith.ai's per-call pricing.

Are Smith.ai and Ruby HIPAA compliant?

Both market to healthcare. Ask each for a signed BAA that covers the exact plan you buy before they handle any patient calls. PhiClaw signs a BAA on every plan.

Can an answering service book into my EHR?

Usually not directly; most take messages or use a separate scheduling tool. PhiClaw books, reschedules, and confirms visits inside your EHR.

Does PhiClaw use real people?

PhiClaw is AI that answers 24/7 and hands off to your own staff when a call needs a human. It does not route calls to an outside call center.

What are good Smith.ai alternatives for doctors?

For medical practices, look for a BAA, EHR booking, and after-hours coverage. PhiClaw, Ruby, and HIPAA-ready voice-AI platforms are the common options; see our voice-AI comparison for the build-your-own route.
