Rahul Sah — Demo video

Lana is a voice AI agent that shops for care on a patient’s behalf. She calls providers, gets real all-in prices, negotiates with the quotes she collects, and books the best option, but only after the patient says yes. The problem is bigger than booking. When people pay for care out of pocket, prices are hidden until they ask. The same braces can cost $3,000 at one clinic and $7,000 at the next, and it’s the same story for dental work, eye care, imaging, physical therapy and many other services. Finding out means calling around, waiting on hold and repeating the same questions. So most people either pay whatever the first place says, or put off care they need because they can’t tell what’s fair. Providers lose too. They spend front desk time answering price calls and give away free consultations to patients who are only comparing prices, and many of those patients never come back. That’s staff time, appointment slots and resources spent on people who were never going to book. Lana fixes both sides. Patients get a clear, honest price and someone who does the calling and negotiating for them. Providers get a patient who already knows the price, has agreed to it, and is ready to book, instead of a free consult that goes nowhere. She opens every call by saying she’s an AI. Every number she reports links to the provider’s exact words and the second they said it, and she only negotiates with quotes she actually received. Those rules are enforced in code, not just in prompts. In the live demo you can talk to Lana as the patient, watch an AI patient and AI clinics, or play the clinic yourself while Lana negotiates with you. During judging she calls demo clinics, each one an AI receptionist with a hidden price sheet, so real offices don’t get demo calls. The demo uses braces, and the same approach works for any care people pay for themselves.
