We are parents from Vancouver. Hey Susan is the assistant we wish we'd had from the sleepless nights of day one. Our baby had jaundice after we came home, and we weren't sure what we were seeing. Logging, charts and allergen tracking are free.

OUR STORY
We took the prenatal classes and sat through the hospital discharge session, and still, after we came home, our baby had jaundice and we had to rush back to the hospital. So we built Hey Susan. It's our small way of contributing back. Build the future of a baby assistant with us.
Not a medical device: she doesn't detect, diagnose or treat jaundice.
A new kind of baby tracking — and beyond...
An AI assistant for pregnancy and childhood. She remembers the little details about your child, messages you first, and nudges you to your pediatrician when something looks off — not a diagnosis. Check-ins that come first are part of optional Max Performance.
Hey Susan runs on nine faculties, modeled loosely on how memory and attention work in the brain — so instead of just logging, she notices. The nine: Notices what’s off · A picture that keeps building · Knows who your baby is · What matters stays in view · Tone that fits the moment · She learns you too · She stays on it · A protective instinct · One purpose behind it all.

DAY RHYTHM THAT FEEDS YOUR REMINDERS
Hey SleepTime! and Hey FeedTime! show your day's rhythm, with nap and feed window estimates from your baby's own logs. Not medical advice.
Window estimates, and the reminders that follow them, are part of optional Max Performance.

NAPS & FEEDS ON YOUR CALENDAR
Download a free calendar file of upcoming naps and feeds.
Optional Max Performance adds Google Calendar. Say yes and Susan adds the next 7 days of nap and feed blocks there. When the plan changes, she asks again before she updates it.

ASK SUSAN, WITH RELATED READING
Under her answers, Susan shows which of your logs she used and, on health topics, a Related reading link to learn more.
She helps you prep for pediatrician visits and milestone windows, always pointing you to your doctor for anything medical.

NOT A MEDICAL DEVICE
Hey Susan is an AI assistant, not a medical device and not a replacement for your pediatrician. She is not a baby monitor: she only knows what you log or tell her. She notices patterns; she does not diagnose. For anything urgent she'll always tell you to call your doctor or emergency services.
