Specialist slots open every day when patients cancel. They fill within minutes — not because you were too slow, but because no one was watching for you. Until now.
Dermatology, orthopedics, cardiology — the first available appointment for new patients is routinely months away, even when you need care now.
Every day, slots open when patients cancel. They're filled by whoever happens to refresh ZocDoc at the right moment. That's not a system — it's a lottery.
ZocDoc alerts notify thousands. You still lose. There's no service that actually books FOR you the moment a slot opens. There wasn't, anyway.
Set it up in two minutes. We handle everything else.
Add the specialist you need — any ZocDoc provider. Set your preferred times, days, and insurance. We also store your clinical intake info (name, DOB, reason for visit) so the bot can fill the booking form automatically without you lifting a finger.
