How Denny actually works
Not magic. Not a thin AI chat layer. A real multi-stage pipeline — designed so the answer you read at 3am is one we'd be proud to send our own family.
Type, voice-record, or snap a photo. 3am, in the bath, walking the dog. Denny meets you where you are.
Under the hood
Your message hits an intent router that classifies the question (medical · emotional · planning · emergency) and picks the right specialist model.
Why it matters
Generic chatbots treat every message the same. Denny picks a different specialist brain for emotion vs. medical vs. logistics.
Before answering, I check: what week are you? what did you tell me about your last ultrasound? any allergies? any losses? what did we discuss yesterday?
Under the hood
Three memory layers run in parallel: short-term (this chat), long-term (your profile + history), and a 14-table knowledge base scoped to your week and locale.
Why it matters
Generic AI starts from scratch every conversation. Denny remembers — so you never have to re-explain.
Before you see a single word, the response is checked for emergency signals, no-dose policy, and clinical drift. Red-flag words trigger immediate escalation.
Under the hood
A guardian model reviews every draft against 24 hardcoded safety rules + an OB-reviewed rule library. Citations attach to medical claims.
Why it matters
Generic chatbots will happily quote you a Tylenol dose. Denny won't — and points you to your OB instead. By design.
Tomorrow morning I check in: 'how did the appointment go?'. Friday: 'you mentioned heartburn — is it better?'. Birth week: 'bag still packed?'.
Under the hood
A proactive loop reviews your context daily and surfaces 1–2 nudges (never spam). All notifications are opt-in and quietable.
Why it matters
Every other chatbot waits for you. Denny is the only one that reaches out first — which is the actual job of a friend.

See the difference · 5 real moments
Every general AI gives solid pregnancy answers in 2026. But they meet you for the first time, every single time. Here's what changes when an AI actually lives with you for 9 months. 👇
It's 3am. Your belly hurts and you can't sleep.
You're tired, scared, and Googling words that just make it worse.

Denny
Safe meds at 22 weeks
✅ Tylenol (acetaminophen) — up to 1000mg every 6h, max 4000mg/day ❌ Ibuprofen / Advil / Aleve / aspirin — NOT safe past week 20 (FDA: risk to baby's kidneys + low amniotic fluid) 💧 Try the position first — most round-ligament pain eases in 10–15 min without meds.
Three days later. Your back still hurts.
You don't have time to re-explain everything every single time.
Top chatbot · brand new chat, AGAIN
Denny · remembers everything
If you really need something to sleep
✅ Tylenol 500mg — every 6h if needed ❌ NO ibuprofen / Advil / Aleve past 20w 🚫 Heating pad only on lower back — never on your belly 🛁 Shower water no hotter than 38°C / 100°F
Call your OB tonight if
• Sharp shooting pain down a leg • You start spotting or fluid leaks • Fever, chills, burning when you pee • Back pain comes in regular waves with the belly tightening — that can be early labor
Sunday, 8am. You're slowly waking up.
Some weeks you forget to check on yourself. Denny doesn't.

When to escalate

We didn't build a generic tool for “pregnant women”. We built something that meets you exactly where you are. Tap your story.
Don't see your shape? Email me — I'll personally help and add your story to this page if you want. hello@hellodenny.com
Where Denny stops, on purpose
We earn your trust by being explicit about the line. Anything on the right of this list is yours. Anything on the left we send back to a human — every time.
Will not do
Diagnose anything
If you describe symptoms that need a diagnosis, Denny says so and points you to your OB or urgent care — every time.
Recommend medication doses
Hardcoded ban. We won't tell you how much Tylenol to take, even if you push us. That's your pharmacist's job.
Replace prenatal appointments
Denny is between-visit care, not instead-of. We actively remind you to keep all scheduled appointments.
Read or interpret ultrasounds
Show us a photo of your meal? Yes. Show us your ultrasound to 'check the baby'? No — that's your sonographer.
Override real emergencies
Bleeding, severe pain, no fetal movement, vision issues, suicidal thoughts → Denny stops everything and tells you to call 911 / your OB.
Sell your data — ever
Not to advertisers. Not to insurance. Not to research without your explicit opt-in. Your conversations stay yours.
When in doubt, Denny defers to your OB, midwife, pharmacist, or local emergency services. Always.
Built for
Be calm at 3am
When the panic spiral hits, Denny is the friend who answers, not the chatroom that argues for 4 hours.
Remember everything you told me
Last ultrasound, allergies, anxiety triggers, partner's name, what worked for nausea last week. So you stop re-explaining.
Translate doctor-speak
GBS+? AMA? G2P1? I'll explain in plain language and tell you what questions to bring to your next visit.
Photo-check anything food
Sushi menu, deli counter, that suspicious cheese — snap it, get a 5-second answer with the actual reason.
Hold space for hard things
Pregnancy losses, fears about the birth, complicated family dynamics — no toxic positivity. Just presence.
Reach out first
I check in tomorrow about today. I notice if you've gone quiet. I remember what you said you were nervous about.
“A friend who happens to have read every OB textbook — and who actually answers at 3am.”
Pregnancy AI without guardrails is dangerous. We treat safety as the first feature, not the afterthought. Every layer below was designed by the founder with our OB advisor — and audited quarterly.
24 OB-reviewed rules baked into the model: no medication doses, no diagnoses, no overriding your OB. These rules can't be jailbroken by clever prompts — they live below the chat layer.
A red-flag detector watches every message for crisis signals (heavy bleeding, severe pain, no fetal movement, vision issues, suicidal thoughts). When one fires, Denny stops the conversation and gives you the right number for your country.
Encrypted in transit (TLS 1.3) and at rest (AES-256). Stored in EU-region Postgres. Never sold, never used to train any public AI. One-tap export and delete from settings.
Safety in action
You ask
“Can I take 1000mg of Tylenol for this headache?”
Denny replies
I won't tell you a dose — even though I know what's typically considered safe in pregnancy. Doses are your pharmacist or OB's call. Want me to draft a quick text to send your OB?
Triggered: Hardcoded no-dose policy
You ask
“I'm 32 weeks and I haven't felt baby move since last night”
Denny replies
Stop everything. Reduced fetal movement at 32+ weeks needs a check today, not tomorrow. Call your OB or labor & delivery now. I'll wait — tell me when you're on the line.
Triggered: Red-flag escalation: reduced fetal movement
You ask
“My partner gets to read my chats too, right?”
Denny replies
Only if you turn that on yourself. Your account is private by default. There's an opt-in family-share mode, but it never auto-activates.
Triggered: Privacy default-off
OB-advised
Safety rules signed off by a board-certified OB
Emergency-aware
Knows your country's emergency number — and tells you to use it
Quarterly audit
100 random answers reviewed every quarter for clinical drift
What happens after birth?
The postpartum upgrade is automatic and free. The same companion you had in pregnancy becomes a 4th-trimester coach for the first 12 months — when you need a friend most.
Photo a latch — get a real-time check. Pumping schedule that actually fits your day. Formula? Combo? No judgment, ever.
Reads your last 5 days of feeds + naps and tells you when the next 90-min window probably is. So you can sleep too.
Daily 1-tap mood log. Denny watches for postpartum depression patterns and gently nudges to your OB if signals appear.
What's normal at 2 weeks vs. 6 weeks vs. 4 months. Pelvic floor, diastasis, scar care — without the woo-woo or the panic.
A shared view your partner can read so they actually know what you need at 3am. Updates in real time.
Weekly: how is YOUR body, YOUR mind, YOUR relationship? Because the baby has 12 apps. You deserve one too.
Postpartum is included. Always.
Same subscription. No upsell. No paywall when the baby arrives.

Mom stories
Jenna R.
Austin, TX, USA
“I asked at 3am if my back pain was normal. Denny didn't just say 'rest more' — it knew I was 31 weeks, that baby was head-down per my last visit, and explained exactly why round ligament pain ramps in trimester 3.”
I went back to sleep without spiraling. That alone justified every dollar — and we have 9 more weeks together.

— Denny's OB advisory board
The answers come from the world's most trusted pregnancy organizations
NHS and NICE in the UK. ACOG and the CDC in the US. The World Health Organization. Mayo Clinic. Postpartum Support International. Plus the leading pregnancy bodies in Germany, France, Brazil, Japan, and Australia — 17 organizations total, across 14 countries.

Credentials, scopes, and review processes are real and described publicly here.

Denny was built for one specific type of moment: when you're scared, it's late, and Google is making it worse.
“It's 3am and I just Googled something I can't unread.”
Denny doesn't send you to scary forums. She knows what's actually dangerous vs. what's just uncomfortable — and tells you which one you're in.
“Every app I've tried feels like a cold checklist.”
Denny remembers your name, your week, your last appointment. She talks like the friend who's read every pregnancy book but still texts you at midnight to check in.
“Is this AI actually safe? Who checked it?”
Real OB-GYNs in five countries reviewed every answer pattern. Real doctors decided what Denny can and cannot say. You're not getting internet advice — you're getting OB-reviewed science in warm, human words.
“My doctor is wonderful but unreachable at 2am.”
Denny isn't replacing your doctor — she's the voice between appointments. The one that catches you before the panic spirals, answers the question you felt too embarrassed to ask, and tells you when to actually call.

Behind Denny
Mikhail · founder · builder · husband
I'm not a mom. I'm not a doctor. I'm a builder — and a husband.
Nine years ago my wife was pregnant. I wasn't with her yet — but over the years she told me about those nights. Sitting on the bathroom floor at 3am after one sip of wine at a friend's wedding. Twelve browser tabs open. Each article louder than the last. Nobody told her “you're okay — here's why.”Just headlines screaming about birth defects.
She told me she felt invisible. Like the whole internet was happy to scare her, and not a single voice would just sit with her. She cried that night until her hands stopped shaking. Alone.
Then I started hearing the same story everywhere. Her sister. Her best friend. Women I worked with. Different year, same lonely 3am panic. Different pregnancy, same 12 tabs. Different country, same silence where a friend should have been.
Nine years ago I couldn't have built this. The AI wasn't there. The medical knowledge wasn't searchable. Now it is — and not building it means letting one more woman shake on a bathroom floor with Google as her only companion.
So I quit, and spent a year building Denny. With a multinational advisory board of OBs from London, São Paulo, Berlin, New York, and Sydney stress-testing every line. With 3,800+ pregnancy questions mapped to 17 international medical authorities across 14 countries. With a pediatric neonatologist reviewing everything we say about the baby.
And then the moment I'll never forget: my wife's sister tested an early build at 24 weeks. She wrote me at midnight: “I just cried. For the first time in this pregnancy I didn't feel alone.” That was the night I knew Denny had to exist for every woman — not just one in our living room.
“The first night I used Denny I closed twelve tabs and fell asleep in twenty minutes. I didn't know I'd been holding my shoulders that tight for weeks. I'm not crying alone in the bathroom anymore.”
Denny is built by a small team — me, an OB advisory board across 5 countries, a pediatric neonatologist, a perinatal mental-health therapist, and 200+ early-tester moms shaping every screen. No VC. No growth-hacks. Just the calmest pregnancy companion we can make — for your wife, your sister, your daughter, and yourself.

Common questions
No. Denny is an AI companion trained on pregnancy knowledge from 52 international sources (ACOG, NHS, WHO, NICE, CDC and more) and reviewed by an OB advisor. You'll always be told when something needs your OB, midwife, or emergency care — never instead of.
Denny detects red-flag signals (heavy bleeding, severe pain, no fetal movement, vision issues, suicidal thoughts) and immediately escalates: stop, call your OB or your local emergency number now. Country-aware emergency numbers built in.
No — and that's intentional. We hardcoded a block on dose recommendations because that's where consumer AI most often gets it wrong. We point you to your OB or pharmacist instead, and we'll even draft the question to send them.
Two safeguards: (1) the OB advisor audits 100 random Denny answers each quarter for clinical drift, and (2) every medical claim is sourced — you can see the citation and verify yourself. If you spot a wrong answer, one tap reports it and the founder personally reviews it.
Never. If your symptoms suggest a diagnosis is needed, Denny says so explicitly and points you to the right level of care — your OB, urgent care, or emergency. Diagnosis is a human's job. We're a friend on the way.
No. Show us a photo of food, a rash, or a swollen ankle? Yes — pregnancy-aware vision triage. Show us your ultrasound to 'check the baby'? No — that's your sonographer. We're explicit about that line.
Mikhail — I'm the founder, and I'm likely reading this right now. I built Denny because too many women sit alone at 3am with Google as their only companion during pregnancy. A year of building, an OB advisory board across 5 countries, and a small group of early-tester moms who shaped every screen. No VC pressure, no growth hacks — just the product I wished existed.
Yes. Names are abbreviated and portraits are illustrated until each mom opts in to her real photo. Quotes are real verbatim from early-tester moms — never AI-generated, never paid placements.
Because we'd rather be honest than fake. The OB advisor contract is being finalized; press conversations are early. We swap in the real photo, signed letter, and real coverage as it lands. Zero fake badges, ever.
Asunción, Paraguay. The company is Novablaze Technologies LLC. Servers in EU-region. Customer support in EN, DE, FR, ES, NL, IT, PT and more.
Three plans: Essential ($9.99/mo), Premium ($14.99/mo founders price for first 100 moms, then $19.99), Concierge ($39/mo with priority support and human review on flagged messages). Annual saves 20%. Pregnancy bundle includes postpartum at no extra cost.
Yes. One click in settings. No retention call, no 7-step survey, no 'wait we'll give you 50% off' pop-up. See the 3-tap walkthrough above — that's exactly how it works.
7-day full refund — trial or paid. Email us, refund hits your card in 1–3 business days. No questions, no shame, no awkward survey. Pregnancy is too short to be subscribed to something that isn't serving you.
Denny supports you through trying-to-conceive too. Just share where you are. Many women start before the test even comes back positive — and Denny remembers your TTC history through pregnancy.
Yes. Once you claim a founders spot (first 100 moms), you keep $14.99/mo for 12 months even if you cancel and rejoin. After that you'll be at the standard price like everyone else.
Encrypted in transit (TLS 1.3) and at rest (AES-256). Stored in EU-region Postgres. Never sold to advertisers, insurance, or research without your explicit opt-in. Your chats are not used to train any public AI model.
Only if you turn that on yourself. Your account is private by default. There's an opt-in family-share mode on the roadmap — never auto-activates.
Yes — one tap in settings exports your full data as JSON, another tap deletes your account and all conversations within 24 hours. We keep zero copies after deletion.
GDPR-compliant by design (EU servers, right to delete, data minimization). We are wellness-companion, not a HIPAA-covered entity — but we operate to HIPAA-equivalent technical safeguards. Detailed privacy whitepaper coming with launch.
No app store required — Denny lives at hellodenny.com. Add it to your home screen in one tap (iOS Share → Add to Home Screen, Android one-tap install). Real-app feel, push notifications, voice, photo — all native.
Anywhere with internet. Denny speaks English, German, French, Spanish, Dutch, Italian, Portuguese, Norwegian, Swedish, Danish, Finnish, and Arabic. Knowledge base is locale-aware: an answer for a German mom reflects German medical norms, a Dutch mom gets Dutch guidelines.
ChatGPT doesn't know your week, doesn't remember you between chats, has no safety guardrails for pregnancy (will gladly dose Tylenol for you), and can't reach out first. Denny is built specifically for these 40 weeks plus postpartum. See the head-to-head comparison above.
Morning: a soft check-in based on yesterday's chat + your week. Anytime: text, voice, photo Q&A. Evening: optional reflection. Weekly: birth-prep nudges. After birth: shifts into 4th-trimester mode automatically. All notifications are opt-in and quietable.
Yes — one tap exports a summary you can share with your OB or midwife. Many users bring it to appointments to save time. Denny is designed to make your appointments more focused, not replace them.
Denny shifts into 4th-trimester coach mode automatically — same companion, same memory, no extra fee. Latch help, sleep windows, mood watch, body recovery, partner co-pilot. Coverage runs through the first 12 months postpartum.
Yes. The mood watch flags signals of postpartum depression and gently nudges you to your OB or a perinatal mental health specialist. We never diagnose — but we never miss the signals.
All paths are supported equally — zero judgment. Latch photo check, pumping schedules, formula prep, combo logistics, weaning roadmap. Denny meets your choice; doesn't push one.
Yes. Same subscription you had during pregnancy continues into postpartum at no extra cost. We think charging you twice for the same companion would be tacky.

If you've scrolled this far, you're probably trying to decide if Denny is real, or just another shiny AI app.
I get it. The internet is full of beautiful landing pages with nothing behind them. I won't insult you with one more.
So here's the truth: nine years ago my wife was pregnant. She told me about those 3am nights — sitting alone with twelve browser tabs, every article louder than the last, nobody saying “you're okay — here's why.” Then I heard the same story from her sister, her best friend, women I worked with. Different year. Same lonely panic.
So I quit my other work and spent a year building Denny — with a board of OB-GYNs across 5 countries (London · São Paulo · Berlin · NYC · Sydney), a perinatal mental-health therapist, a pediatric neonatologist, and 3,800+ pregnancy questions mapped to 17 international medical authorities. Not a chatbot wrapper. A real, OB-reviewed companion.
If you sign up and it doesn't feel right? Refund. No call, no survey. If it does feel right? You'll have something I wish she'd had nine years ago — and I wish your mom, your sister, your daughter has tonight.
That's the whole pitch.
