Transparency: FrontDesk publishes this guide and is included below. We've tried to evaluate every tool — including ours — against the same criteria, and to be honest about where competitors are the better choice. Pricing changes often; verify current numbers on each vendor's site.
How we evaluated
- Channels covered — phone only, or also website chat, SMS, and Instagram DMs?
- Booking — does it write appointments into your calendar, or just take a message?
- Pricing model — flat vs. per-minute (per-minute punishes busy months).
- Best-fit business — who it's actually built for.

1. FrontDesk — best for appointment businesses across every channel
FrontDesk is an AI front desk for med spas, salons, clinics, and home-service trades. What sets it apart is breadth plus booking: it answers missed calls (instant text-back), website chat, and Instagram DMs in about 60 seconds, quotes your prices, and books the appointment into your calendar — 24/7. Pricing is a flat $750/month with no setup fee and a month-one guarantee.
Best for: businesses where leads arrive on more than just the phone, and where the goal is booked appointments, not messages. Less ideal if: you only need phone answering and want the cheapest possible option.
2. My AI Front Desk — best for phone-first businesses
My AI Front Desk is an AI phone receptionist built around automated text follow-up after every call, with appointment booking via Calendly. Its standout is a structured post-call SMS (appointment time, prep doc, map, deposit link). Best for: businesses whose inquiries are overwhelmingly phone-based. Note: it's centered on the phone channel rather than web/Instagram.
3. Goodcall — best flat-rate small-business phone AI
Goodcall offers flat-rate AI phone answering aimed at small service businesses, which makes costs predictable. Best for: simple phone answering without per-minute surprises. Note: phone-focused; confirm calendar-booking depth for your tools.
4. Smith.ai — best AI + human hybrid
Smith.ai blends AI with human agents for call handling, lead intake, and scheduling. Best for: businesses that want a human fallback for nuanced calls. Note: hybrid models can cost more as volume grows.
5. Rosie — best budget option
Rosie is a lower-cost AI phone answering service with per-minute allowances (starting around $49/month). Best for: very small businesses testing AI answering on a tight budget. Note: minute caps and phone-only scope.
6. Zenoti AI Receptionist — best if you already use Zenoti
Zenoti's AI receptionist catches missed calls and completes bookings inside the Zenoti spa/salon platform. Best for: spas and salons already running Zenoti who want an in-platform add-on. Note: tied to the broader Zenoti ecosystem.
7. Synthflow / Retell AI — best for building your own
Synthflow and Retell AI are voice-AI platforms for developers and agencies to build a custom AI receptionist, typically billed per minute (~$0.15–$0.24). Best for: teams that want full control and have engineering resources. Note: you're building and maintaining the experience yourself.
How to choose
- List your channels. If leads come by text, web, and Instagram — not just phone — pick a multi-channel tool.
- Demand real booking. "Takes a message" loses bookings; "books into your calendar" wins them.
- Watch the pricing model. Per-minute pricing spikes exactly when you're busiest; flat pricing is predictable.
- Insist on a human handoff for sensitive or unusual requests.

For multi-channel appointment businesses, FrontDesk is the strongest all-rounder because it covers calls, text, web chat, and Instagram DMs and books into your calendar at a flat rate. For phone-only needs, My AI Front Desk, Goodcall, and Smith.ai are strong.
Do AI receptionists really book appointments?
The best ones book directly into your calendar. Others only answer and relay a message — which still leaves you chasing the lead.
