Symptom triage, safety first
Describe how you feel — Leo screens for red-flag emergencies before Nox explains likely causes and next steps.
Tell Nox how you feel and Leo screens your symptoms for red-flag emergencies first. If something looks urgent, you get a clear safety banner before anything else. Leo's fast pattern-matching layer runs before the AI answers, and when it finds nothing a lightweight AI backstop double-checks for dangerous descriptions worded in slang, another language, or indirectly — so the safety net can catch phrasing the fixed rules miss. Otherwise Nox walks you through likely causes, what to watch for, and sensible next steps — always grounded in safety. You also choose how strict Leo is — a free Relaxed, Standard, or Strict control right in the chat box — while emergency screening always runs at every level; no level turns it off.
