AI Insight
A useful answer should be inspectable.
Grack combines the wellness context you choose to share with explicit guardrails and published evidence. It should show how it reached an answer, where the evidence came from, and where its role ends.

Anatomy of the answer
One question. Four visible checks.
01
Personal context
Start with your record
The answer reads the current plan — Wegovy 2.4 mg at week 40 — and calculates 100.0 to 80.0 kg as 0.5 kg per week.
02
Careful interpretation
Describe; do not diagnose
It calculates the observed pace, then states what the numbers cannot establish about your health or treatment.
03
Published evidence
Make the source inspectable
Every recommendation in this example is grounded in peer-reviewed journals, authoritative guidelines, or expert consensus, with numbered citations that keep the evidence trail inspectable.
04
Clinical boundary
Return decisions to care
The answer never changes medication. Diagnosis, prescribing, dose changes, and individual clinical judgment remain with your clinician.
