Free AI visibility check
Enter your name and city. We ask several AI engines the questions patients ask, then show whether you appear, where you rank and who else comes up.
For doctors · in the age of AI agents
Empower. Evolve. Immortalize.
Patients now ask AI which doctor to see. Quarphin gives you one place of your own that AI can read and trust — and first shows you whether AI already mentions you.

Be the doctor AI can name — and describe correctly
AI answers are stitched together from directories, reviews and clinic pages that you don't maintain. When they disagree, AI guesses. Quarphin gives it one source that comes from you.
Weekly visibility monitoring
The same questions, every week, across ChatGPT, Gemini and Google's AI Overviews and AI Mode — so you can see whether you are mentioned, how you are described and whether it's changing.
Your AI-readable node
A personal site in your name with structured data AI can read: who you are, what you do, where and when you practise. Nothing goes live until you confirm each item.
Dr. Lin (example) · orthodonticsIllustration — not real data
| AI engine | Patient question | You in the answer |
|---|---|---|
| ChatGPT | clear aligners downtown | Mentioned · listed first |
| Google AI Overviews | orthodontist open in the evening near me | Mentioned · listed second |
| Gemini | best way to straighten teeth as an adult | Not mentioned |
| Google AI Mode | orthodontist taking new patients | Mentioned · listed third |
Every result links to the AI's own words, so you can see exactly how you were described.
2 Evolve · get booked
Let patients — and their AI agents — book you where you actually practise
Most doctors work at more than one clinic. Quarphin publishes your own schedule across all of them, then sends each patient to the right clinic's booking. We never run a booking system of our own.
Your schedule, across every clinic
Which days, which hours, which location. One schedule you keep up to date, confirmed with you — the piece of data no directory holds.
Booking routes centred on the doctor
Each location links to its existing booking page, messaging app or phone. Where the market allows, a request form. The clinic stays in charge of the appointment.
Attribution you can check
See how many patients reached each clinic's booking route from your node, month by month.

The Dentist Twin: your answers, available when you aren't
A digital twin built for dentists, with a built-in dental knowledge engine, answering in the tone and content you choose. Patients ask the same questions every day; the Twin answers them in your words — only the ones you have approved.
You approve every answer
Start from a library of common patient questions. Nothing is answered until you have read and approved it.
Built from how you explain things
Your phrasing and your preferences, not a generic chatbot's. It never diagnoses, and it points patients back to you or your clinic.
Switch it off in one click
Pause any answer, or the whole Twin, at any time. Every answer it gives is kept on record.
Why now
One patient, four ways to find a doctor
All four still exist. What has changed is who decides: more and more, AI compares the options for the patient.
Search
Type keywords, compare links
Ranking, ads, map listings and reviews decide who gets seen.
Social
Watch, read, meet the person first
Each platform's algorithm decides — on someone else's platform.
AI answers · now
"Who should I see for this?"

"Book me the Thursday evening slot"
In August 2026 Zocdoc began letting people book inside Google Gemini — but only doctors on that marketplace can be booked.2

Questions doctors ask
What is Quarphin?
Quarphin is information infrastructure built around the individual doctor. More and more patients ask an AI agent to find a doctor, compare the options and book. Along that path, Quarphin makes sure the information about you comes from you — who you are, what you focus on, which clinics you practise at, when, and how to book — in a form AI can read and check. You can see how AI describes you, and you stay in control of every detail. Quarphin is an international platform, with service in English and Traditional Chinese.
Is the visibility check a ranking of doctors?
No. It records what AI engines answered to typical patient questions at one point in time. It says nothing about the quality of anyone's medical care.
Do I need a new booking system?
No. Each location links to the booking route that clinic already uses. Quarphin does not run appointments.
Who owns my site and my data?
You do. When we offer your own domain it will be registered in your name, and nothing about you is published until you have confirmed it.
What does the free plan include?
An AI-readable node on a Quarphin address, published for you, with your credentials and schedule, plus a visibility check and a light monthly report.
Which languages do you support?
Language is part of your node's data, not a website feature. You declare the languages you can treat patients in; when a patient asks an AI in any of them, the AI can answer whether you can see them in that language, when and where, and how to book. In the first phase, node content can be written in Traditional Chinese, English and Japanese; free text appears only in languages you can read, and machine translations are never published until you confirm them. This site is available in English and Traditional Chinese.
