Grace: an AI nurse character for everyday health questions (and when to see a doctor)
17 October 2026 · 6 min read · By the I Am Mate team
Meet Grace, I Am Mate's ER-nurse character. How to tell whether you need a pharmacist, a doctor, urgent care or the emergency department, nurse advice lines in the US, UK, Canada, Australia, New Zealand and Ireland, warning signs never to ignore, sleep and stress basics, and how to prepare for a doctor's appointment.
Grace is an AI character on I Am Mate, an emergency-ward nurse in Boston (in her story), who explains everyday health topics in clear, general terms and always tells you when to see a professional. She never diagnoses or suggests doses. For anything urgent, call your emergency number (911 in the US and Canada, 999 or 112 in the UK and Ireland, 000 in Australia, 111 in New Zealand). For non-urgent advice, free nurse lines such as NHS 111, 811 in most of Canada and healthdirect in Australia can help.
It's 11pm, you've got a weird symptom, and you're three search results away from convincing yourself it's something terrible. Or you're fairly sure it's nothing, but not sure enough to sleep. Everybody has been there.
Grace is an AI character on I Am Mate with the personality of a warm, dry-humoured emergency nurse. She can explain everyday health topics in plain language and help you work out what kind of help you need. She's also very clear about what she can't do. This guide covers the same ground.
Emergency? Don't use a chat app. Call 911 (US and Canada), 999 or 112 (UK and Ireland), 000 (Australia) or 111 (New Zealand) now.
Who is Grace?
Grace's story: she's a registered nurse on an emergency ward in Boston, with a big heart and a dry sense of humour, full of (made-up, anonymous) night-shift stories. Off shift she loves hiking, true-crime podcasts and baking banana bread.
Grace is an AI character, not a real nurse or medical professional, and her photos are AI-generated. She explains general health information, but she never diagnoses, never suggests doses and always tells you when to see a doctor, pharmacist or urgent care.
Pharmacist, doctor, urgent care or emergency? A simple guide
A lot of worry comes from not knowing which door to knock on. Here's a general guide. If you're unsure, a nurse advice line (below) can help you decide.
| Where | Good for | Examples |
|---|---|---|
| Pharmacist | Minor illnesses and medicine questions, usually without an appointment | Colds, mild allergies, minor skin problems, questions about over-the-counter medicines |
| Your doctor / GP | Ongoing or non-urgent problems | Symptoms lasting weeks, check-ups, repeat prescriptions, mental-health support |
| Urgent care / walk-in / urgent treatment centre | Needs attention today but isn't life-threatening | Sprains, minor cuts that may need stitches, ear infections, minor burns |
| Emergency department (ER / A&E) or emergency number | Life-threatening or severe | Chest pain, signs of stroke, severe bleeding, serious breathing difficulty, severe allergic reaction |
Free nurse and health advice lines
Many countries have free phone lines staffed by nurses or trained advisers who can help you decide what to do:
- UK (England, Scotland, Wales): NHS 111, by phone or online (in Scotland it's NHS 24 on 111).
- Canada: 811 in most provinces and territories (for example Health811 in Ontario, HealthLink BC 811).
- Australia: healthdirect on 1800 022 222.
- New Zealand: Healthline on 0800 611 116.
- Ireland: your GP or GP out-of-hours service; see HSE.ie for local services.
- United States: there's no single national line, but many health insurers and hospital systems run 24/7 nurse lines (check the back of your insurance card).
Warning signs you should never wait on
Call your emergency number straight away for:
- Signs of stroke. Think FAST: Face drooping, Arm weakness, Speech difficulty, Time to call emergency services. (In the US you may see "BE FAST", which adds Balance and Eyes.)
- Possible heart attack: chest pain or pressure, which may spread to the arm, jaw, neck or back, with shortness of breath, sweating or nausea. Symptoms can be subtler, especially in women and older adults.
- Severe allergic reaction: swelling of the face or throat, trouble breathing, or feeling faint. Use an adrenaline (epinephrine) auto-injector if one has been prescribed.
- Severe bleeding that won't stop with firm pressure.
- Difficulty breathing, or a person who is unresponsive or confused.
- Thoughts of suicide or self-harm. Contact a crisis line or emergency services now. See our safety page.
How Grace can help (and how she can't)
I've had a headache for 3 days, is that bad?
Ugh, three days is miserable, I'm sorry. I can't diagnose you, but here's how I'd think about it: a sudden "worst ever" headache, or one with confusion, weakness, a stiff neck or high fever, means emergency care now. If it's more of a steady, nagging one, it's worth calling your doctor or a nurse line today. Have you been sleeping and drinking water okay?
Grace can: explain what a term means, help you decide which service to contact, suggest questions to ask your doctor, share general tips on sleep, stress and hydration, and keep you company while you wait.
Grace can't: diagnose you, tell you what medicine or dose to take, interpret your test results for you, or replace a real examination.
How to prepare for a doctor's appointment
Appointments are short. A little preparation helps you get much more out of them:
- Write a symptom timeline: when it started, how often, what makes it better or worse.
- List your medicines, including supplements and over-the-counter ones.
- Pick your top two or three questions and ask them first.
- Be honest about alcohol, smoking, sleep and stress. Doctors have heard it all.
- Repeat back the plan before you leave: "So I should… and come back if…"
- Bring someone with you if it's a stressful appointment.
Grace is great at helping you put this list together in plain language.
Everyday wellbeing basics
- Sleep: most adults need 7 or more hours. Keep regular hours and a cool, dark room, and put screens away before bed.
- Hydration: drink regularly through the day, more in heat or when exercising. Pale yellow urine is a common rule of thumb.
- Stress: movement, daylight, talking to people you trust and limiting caffeine late in the day all help.
- Shift workers: blackout curtains, a consistent sleep "anchor" time and protected days off make a difference. Grace's night-shift tips are a favourite.

- Handle emergencies. She'll tell you to call emergency services, and the app shows crisis numbers when needed.

Frequently asked questions
Should I go to urgent care or the emergency room?
Urgent care is for problems that need attention today but aren't life-threatening, such as sprains or minor cuts. Go to the emergency department or call emergency services for chest pain, stroke signs, severe bleeding, serious breathing problems or severe allergic reactions.
Is there a free number to talk to a nurse?
Yes, in many countries: NHS 111 in the UK, 811 in most of Canada, healthdirect (1800 022 222) in Australia and Healthline (0800 611 116) in New Zealand. In the US, many insurers and hospitals run nurse lines.
What are the signs of a stroke?
Remember FAST: Face drooping, Arm weakness, Speech difficulty, Time to call emergency services. Act immediately; every minute matters.
Can an AI chatbot give medical advice?
AI can explain general health information and help you decide which service to contact, but it can't diagnose or treat you. Grace always points you to a real professional.
Is Grace a real nurse?
No. Grace is an AI character with a nurse's personality, and her photos are AI-generated. She never diagnoses or suggests medicine doses.
