The same number means
different things at different ages.

38.4°C at 3 weeks is an ER visit. 38.4°C at 14 months with a cough is usually paracetamol and watch. Fever AI is the first pediatric triage tool that knows the difference — by age, by protocol, in 10 seconds.

The four protocols

One product, four ages, four protocols

Mila picks the right protocol from your baby's date of birth. Most symptom checkers do not. This is the wedge.

  • 0–28 days

    Any T ≥ 38.0°C rectal → ER now

    Per Philadelphia / Rochester criteria, neonatal sepsis cannot be ruled out without lab work.

  • 29–90 days

    T ≥ 38.0°C → call within 1h

    Urgent evaluation per NICE NG143; viral vs bacterial cannot be distinguished clinically alone.

  • 3–36 months

    T ≥ 39.0°C without source → call today

    AAP & NICE: numeric threshold less important than associated symptoms and toxicity signals.

  • > 36 months

    Symptom-led triage

    By this age fever alone matters less; red flags drive the level.

Output — four triage levels

You get a decision, not a probability

  • Watch

    Monitor 24–48h, recheck in 4h. No call needed unless symptoms change.

  • Call today

    Reach your pediatrician within the day. Not urgent, but worth a phone consult.

  • Call now

    After-hours pediatric line within 1 hour. Don't wait until morning.

  • Emergency

    112 / 911 now. Do not wait. Hard-coded for 7 red-flag combinations.

What it is NOT

Not a medical device. Not a diagnosis.

Fever AI is informational support for parents — a structured triage hint that tells you when to call your pediatrician and how soon. It does not diagnose, does not prescribe, and does not replace clinical judgement. Seven hard-coded emergency overrides surface 112 / 911 immediately for the situations that cannot wait.

Frequently asked

Is Fever AI a medical device?+
No. Fever AI is informational support for parents. It helps you decide when to call your pediatrician — it does not diagnose. EU MDR posture: not a device. AAP-style disclaimers throughout.
Why is age so important?+
38.4°C in a 25-day-old is an ER visit (Philadelphia Protocol). The same temperature at 14 months with a cough is usually 'watch'. We map four distinct clinical protocols by age — most symptom checkers don't.
What if my baby has petechiae or stops breathing properly?+
Seven hard-coded emergency gates bypass the AI entirely and surface 112 / 911 immediately. Petechiae + fever, respiratory distress, active seizure, unresponsive, neonatal fever, bulging fontanelle, neck stiffness. No model latency in the moments that matter most.
Can I see how Mila reached her decision?+
Yes — every reading includes the full reasoning chain. Step 1: which protocol was selected and why. Step 2: the normalised rectal-equivalent temperature. Step 3: the rule applied. No symptom checker exposes its reasoning. We do.
How does dosing help?+
When you tell Mila your baby's weight + which antipyretic you gave + when, she computes the safe re-dose window (paracetamol 4-6h, ibuprofen 6-8h) and the correct mg-per-kg dose. No more math at 2 AM.

When the thermometer beeps at 23:30.

Three free readings a month, no card asked. Mila reads against the right pediatric protocol for your baby's exact age.
