AI receptionist

You close at six. Your phone doesn't have to.

Synthropia answers the calls your team can't take — in the morning rush, over lunch, after hours — books the appointment into your calendar and texts a confirmation.

Two customers at the desk, the phone rings again. Synthropia picks up.21:47 — you're closed. A new customer calls and is booked for 9:30 tomorrow.

The problem

A call nobody answers is a customer who goes elsewhere.

People who need you now don't leave voicemails. They call the next name on the list.

Everyone is busy

With a client, on a job, at the desk taking a payment. The phone rings out.

You're closed

Evenings and weekends are exactly when people finally have time to call — and when nobody is there.

Voicemail waits till morning

By the time someone calls back, the customer has already booked somewhere that answered.

Listen

Call the clinic. You pick the lines.

You're the patient calling a dental clinic. Toothache or whitening, which slot, text or email — you choose, and the assistant books it, asks the right questions and sends the confirmation. Generated by our production voice stack.

Want it unscripted? Get a live demo call — it rings your phone in about a minute.

1–2 minutes, your choices

You play the patient: pick each reply and hear how the receptionist handles it. Toothache or whitening, the slot, text or email — every path is different. The clinic, dentist and patient are fictional; the receptionist's voice comes from our production voice stack.

Straight talk

No invented testimonials here

We're a small team from Szczecin, Poland, with our first customers live. You won't find made-up reviews or "300% more bookings" on this site. When a customer lets us publish real numbers, you'll see them — with their name.

Until then, judge it the fair way: get the demo call, and run your own numbers.

Questions people ask first

Will callers know they're talking to an AI?
Yes, and we recommend it. The receptionist introduces itself as your AI assistant. The sample call on this page was generated by our production voice stack. Most callers care about getting an appointment quickly, not about who picks up — but nobody should be misled.
What if a caller needs a real person?
It can transfer the live call to your staff, or take a clear message — name, number, reason — and flag it for your team to call back. You decide which situations always go to a human.
Which languages does it speak?
Polish and English are in production today, and we've tested real calls in Ukrainian, German, Spanish, Portuguese, Cantonese and Mandarin. Ask us about yours.
Does it send SMS confirmations?
Yes — every booking gets a text-message confirmation, plus a reminder before the appointment.
Can it transfer a call to my team?
Yes. It can transfer a live call to your staff, or take a message for a callback — your choice per situation.
Do I have to replace my phone system?
No. You keep your number. Calls you can't pick up — busy line, lunch, after hours — are forwarded to Synthropia. Setup often takes just a few days. We help you set up the forwarding.
How much does it cost?
Pay-as-you-go from $0.38 per minute, or a monthly plan from $99. See pricing.
