About

Mellivora

Features
Read full description

Mellivora is a hand-reviewed research panel for practicing clinicians in the United States. Physicians, nurse practitioners and physician assistants are paid, in cash, to talk about their own field. You are not filling in a form. You have a conversation. PAID VOICE INTERVIEWS, ON YOUR SCHEDULE Open the app, tap Start, and talk for around twenty minutes about something you actually know: how you sequence a therapy, what moves you off a first-line agent, the case that changed your mind. No calendar invite, no panel of strangers, no travel. Start at six in the morning or at ten at night, pause mid-sentence, and pick it back up later. Every completed conversation is paid, and your earnings and payment history sit in the app where you can see them. SHORTER PULSES WHEN YOU ONLY HAVE A FEW MINUTES Some studies are quick: a handful of structured questions, sometimes with one optional voice answer at the end. Eight minutes, paid the same way. A CONVERSATION THAT REMEMBERS The chat knows what you have already told it. It will not ask you the same question twice, and it will pick up a thread you left hanging three weeks ago. You can also start a conversation about nothing in particular, on a topic you choose. A PERSONAL READ ON HOW YOU REASON After your conversations you get a profile that is yours alone: how you weigh evidence, what drives your decisions, where your thinking is unusual. It is built from your own words, and it sharpens with every conversation. You can see how you compare with anonymized peers in your own specialty, never against generic "physicians", and you can put a question to yourself or to the peer pool and get an honest read back. INVITATION ONLY, AND VERIFIED Mellivora is not open sign-up. Every member applies, records a short hello video, and is checked against professional registries before they are approved. That is what makes the panel worth being in, and it is why clients pay properly for the time. TYPE INSTEAD, IF YOU PREFER Every voice conversation can be typed instead. Pick voice or typing before you start, and the conversation keeps that choice to the end, through every pause. WHAT WE DO WITH WHAT YOU SAY Your answers are used for research, reported to clients in aggregate and anonymized form, and your comparison with peers is anonymous in both directions. Your name is not attached to what you tell a client. NOT A MEMBER YET? Apply at mellivora.ai. Applications are reviewed by a person, and you will hear back within a couple of days.
