Meet the Founder
As a third-year medical student, I've seen overrun emergency departments first hand, patients waiting hours for care they may not have needed, while others delayed seeking help they urgently did. I built ERorNOT to help bridge that gap, offering guidance for new parents, caregivers, and anyone concerned about their health to navigate complex medical guidelines and decide what level of care is right for them.
This is an AI-powered tool to support your decision, not medical advice. Ultimately, you know yourself best.
ERorNOT is not a substitute for professional medical advice, diagnosis, or treatment. Always seek the advice of your physician or qualified health provider with any questions about a medical condition. In an emergency, call 911 immediately.
Our Commitment
ERorNOT was built on a simple principle: access to health guidance should never be gated behind a subscription. We do not believe in profiting from your health concerns. The purpose of tools like this is to serve those who need them most, and that means keeping them accessible to everyone, at no cost.
No subscriptions, no hidden fees, no paywalls. ERorNOT is and always will be free to use.
We do not believe in profiting from people's health concerns. Healthcare guidance should never come with a price tag.
The people who need this guidance most are often those least able to pay for it. We built ERorNOT to remove that barrier completely.
Clinical Foundation
ERorNOT's triage logic is modeled after recognized emergency-care standards. These guidelines inform how we interpret your symptoms, but the tool is for guidance only, not diagnosis.
A five-level emergency department triage algorithm developed by the Agency for Healthcare Research and Quality (AHRQ). ERorNOT uses ESI's decision-point structure to map symptoms to a care level.
The 2021 CDC/ACS National Field Triage Guidelines for the Injured Patient inform our mechanism-of-injury risk weighting, helping flag high-risk trauma scenarios.
Recognized warning signs of acute stroke and heart attack (FAST criteria, chest pain patterns) are treated as immediate, life-threatening triggers.
Age-based risk adjustments account for atypical presentations in infants, children, and older adults, where symptoms can escalate quickly.
A note on scope: ERorNOT synthesizes these guidelines to support your decision about where to seek care. It is not a substitute for professional medical evaluation, and it does not consider every possible condition. If you believe you are experiencing a medical emergency, call 911 immediately.
Answer a few quick questions about your symptoms, injury, and condition to get a recommendation on the right level of care.
ERorNOT provides guidance to support your decision, not replace professional medical advice. Always seek immediate care in emergencies.
