Check In

Check In fits into your life,
not the other way around

Wherever you are with GLP-1s: on one, starting, switching, still deciding, or helping someone you love. It meets you there and picks up where you left off.

Just text it

No app, no account, no forms. Text a question the way you'd text a friend, and get a short, straight answer back.

Get Started

It remembers you

Tell it once what you take, your shot day and what you're working on. Every answer after that fits you.

Get Started

Safe by design

It never tells you to change a dose, and it says when something is one for your prescriber. Urgent symptoms get a call-911 message, every time.

Meets you where you are

On one, starting, switching, still deciding, or asking for your kid. Check In figures out where you are from what you say, and goes from there. No forms, no keywords.

(3)

Remembers what you tell it

Your medication, dose, shot day and what you're working on. Mention it once in conversation, and every answer after that is about you.

On one now7.5 mg weeklyShot day: SundayWorking on: nausea
Sat 7:30 PM
since tomorrow is your shot day, keep tomorrow's dinner small and protein-first, and have ginger tea on hand. that helped last week.

Knows its limits

It's an AI, not a doctor. It never tells you to change a dose, it points you to your prescriber when that's the right call, and urgent symptoms always get a call-911 message.

(5)

Every step of your GLP-1 journey

Your first dose, nausea, constipation, food noise, protein, plateaus, dose changes. One thread for all of it.
