Hi Product Hunt, I'm Warren. I built Hey Susan with my wife Joanna after the scariest week of our lives. When our son was three days old, he stopped feeding. We had been awake for three nights, typing his symptoms into a chatbot at 3am. It gave good general answers, but it had no idea this was our baby, on day three, with a pattern building since Tuesday. The next morning his bilirubin was high enough that we went straight in for phototherapy. He's fine. But Joanna and I kept coming back to the same thought: we had tools, the tools just didn't know us. Hey Susan is the assistant we wish we'd had. She's a real app, free to download on iPhone and Android, built around nine faculties modeled loosely on how memory and attention work in the brain. You text her in plain words ("fed 4oz at 9am", "wet diaper", "she finally napped") and she logs it, remembers your baby, and messages you first when something looks off. HeyJourney! lays out the whole road, pregnancy through age 18. What she won't do: diagnose, replace your pediatrician, or improvise in an emergency. Crisis and 911 routing is hard-coded and bypasses the AI entirely. She plans ahead too. Hey PlanforMe! takes the rhythm she's learned from your own logs and lays the coming week out as blocks on your calendar, showing you the whole proposal and waiting for a yes before a single block exists. And because the person you snap at most is usually the one on your team, HeyBeNice! is a private drafting pad for the hard thing: you say it however it comes out, Susan hands you back a kinder version, and you send it yourself. Your first 31 days on Hey Susan are free, counted from the day you sign up, no card to join. We would genuinely love your questions, including the hard ones about safety and privacy. Warren & Joanna
