HAL — the private baby log in your group chat.

Protect your baby's routine.

Pediatricians stress it: predictable days help babies settle and sleep. HAL keeps parents, grandparents, and sitters protecting one routine — in the chat you already have, private by design.

Family group chat where HAL warns that Leo will likely need to nap in 20 minutes and a parent starts wind-down

How it works

Add HAL to the family thread

One text to start — no sign-up form, no download, no new accounts for anyone.

Everyone texts in naturally

Feeds, naps, notes — HAL understands plain language and keeps one shared record, so every caregiver follows the same routine instead of their best guess.

Ask back any time

"What's the schedule today?" HAL has the full picture and tells you what is likely next from your baby's own rhythm.

Consistency, without the nagging

Create predictability for your little one.

Parents, nanny, grandma—everyone logs feeds and naps the way they already talk. HAL keeps one record straight and holds the routine steady across handoffs, so the day stays predictable no matter who's holding the baby. Predictable days are easier on everyone—especially the baby.

One thread. Three calmer moments.

Everything here is a real part of HAL: shared logging, day summaries, and useful heads-ups.

Everyone stays in sync.

Whoever is on duty just texts the thread. Handoffs stop feeling like a briefing.

03 · STAY AHEAD

The day comes to you.

Appointments, weather, and the drive show up together—before the morning gets noisy.

The household, connected

Bring the whole day into one place.

No shared passwords. No per-seat fees. No “did you put it in the app?” HAL follows the conversation and keeps the useful parts organized.

Built for the 3 AM version of you

Less managing. More knowing.

HAL lives where the family already talks and turns small updates into a clear picture everyone can use.

Natural in. Useful out.

“4oz at 3:15” is enough. HAL understands the update and keeps the day current.

It holds the routine steady.

Nap windows and feed rhythms, sized to your baby's own pattern — so handoffs don't reset the day, and nobody's guessing.

No app. Ever.

One thumb, one text, screen off. There is nothing new for the household to download or maintain.

Yours, and disposable.

Say “export” for your full log. Say “forget me” and everything is permanently deleted.

Protect your baby's privacy

Your baby's data stays in the family.

Baby-tracker apps come with accounts, ad networks, and analytics. HAL is a text thread. Your baby's first months are recorded where they happen—in your family's chat—and your household's information helps your household, nobody else.

  • Never sold, never ads, no third-party trackers
  • Never used to train anything
  • Export or permanently delete it by text

Good to know

Questions, answered.

Do we all need to install something?

No. HAL works over text. Add HAL to the family thread and everyone can participate from the messaging app already on their phone.

What can HAL keep track of?

HAL can log feeds, naps, wake-ups, and other baby-day updates, summarize the day, and estimate what is likely next from your baby's own recent rhythm.

Can I get my data back?

Yes. Text “export” and HAL will prepare the log as a file. Text “forget me” to permanently delete the household's stored data.

Does it help at pediatrician visits?

It helps you arrive prepared. HAL keeps an accurate day-by-day record—feeds, naps, diapers—so you can answer “how many wet diapers?” from the log instead of 3 AM memory, and export it to bring along.

Is HAL medical advice?

No. HAL is a household coordination and logging assistant, not a medical service. For health concerns, contact your pediatrician or another qualified professional.
