Hey Susan

I'm Warren, founder of Hey Susan, an AI assistant for new parents. Today's the milestone: we're live on Product Hunt (https://www.producthunt.com/posts/hey-susan).

Quick backstory on why this exists: my wife Joanna and I took the prenatal class, sat through the discharge briefing before we left the hospital, asked questions, but nobody specifically told us what to watch for, signs of jaundice, whether our son was getting enough colostrum, whether he was feeding enough. By day 4 he was jaundiced enough that he needed to be admitted for phototherapy. At 3am that night we described what we were seeing to a generic AI chatbot because we didn't know who else to call at that hour. It flagged the pattern as jaundice and told us to get him checked. We brought him in that morning and it was confirmed. He's totally fine now. But the chatbot that helped us didn't know anything about our baby, it had no memory of the pattern building since day one, it just got lucky that we described the right symptoms at the right time.

That gap, no memory, no proactive checking, is what we built Hey Susan to close. You text her in plain language ("fed 4oz at 9am," "wet diaper," "she finally napped") and she remembers your baby specifically and messages you first if a pattern looks worth a second look. She never diagnoses anything and she's not a replacement for your pediatrician. Crisis and 911 situations are hard-coded to bypass the AI entirely and route straight to real help.

Where things stand: real native apps, live on both iOS and Android right now, not a Telegram bot or a web wrapper. Free to use during early access, no card required to start. Paid tier ($99/yr or $14.99/mo) is public on the site for when that opens up, no hidden upsells. The hardest part to build wasn't the chat interface, it was the memory and proactive-messaging layer, most chat-based baby trackers are stateless and make you re-explain your kid every time.

Would love feedback from this community, including the critical kind, and especially from anyone who's built in health or parenting and thought hard about the line between "helpful" and "medical advice." That's the single hardest product call we've made.

At 3am, four days into my son's life, he wasn't feeding well and had stopped making wet diapers. We'd been up for three nights straight and couldn't tell if this was normal newborn stuff or something wrong.

We asked ChatGPT. It flagged the pattern as likely jaundice and told us to get him checked. We did, and his bilirubin was high enough that he needed phototherapy. He's fine now, but the moment stuck with me. So much depended on us remembering to ask the right question, to an assistant with no memory of our baby and no way to check in on us first.

That gap is why I built Hey Susan, with my co-founder (and wife) Joanna.

She's not another logging app. She runs on nine faculties, modeled loosely on how memory and attention work in the brain, so instead of just recording what you tell her, she notices. Text her "fed 4oz at 9am" in plain English and she remembers it, watches the pattern over time, and reaches out first when something drifts.

She's an AI assistant, not a medical device. She notices patterns, she doesn't diagnose, and every nudge points back to your pediatrician. There's a hard-coded safety floor underneath too: a short list of true emergency phrasings routes straight to "call your doctor now," no model involved.

Native iOS and Android, both just submitted for App Store/Play Store review. Free in private beta, with $14.99/mo or $99/yr planned once we open up more broadly.

Genuinely curious what this community thinks of "assistant, not companion" as a positioning bet. I think the warmth has to live in the product, not the marketing, but I could be wrong.

Still more features to come. As our baby grows we'll run into more challenges, and I hope this app can help us and other families too.
