How it works
You describe your symptoms
In plain language — fatigue, brain fog, POTS, sleep issues. The AI parses your words with medical context awareness.
AI maps your case
GraphRAG traverses a medical knowledge graph — spike protein pathology, autonomic dysfunction, inflammation markers — finding the specific pathways relevant to you.
Personalized plan generated
Your phenotype classification (neurological, cardiovascular, inflammatory…), severity rating, and a complete recovery plan — exercise, supplements, diet, monitoring schedule.
Progress tracked, plan adapts
As you log symptoms and upload labs, the AI updates your plan. A protocol that worked at month 1 is refined when your HRV improves — automatically.
8 Clinical Assessments
PHQ-9, GAD-7, LC-ANS-12, COMPASS-31, FSS, PSQI, LC-COG-10 and Bell’s Scale — the same tools used in long COVID clinics.
30+ Biomarker Analysis
CRP, IL-6, D-Dimer, HRV, thyroid, immunoglobulin — with Long COVID-specific reference ranges, not just standard labs.
tVNS Optimization
Analyzes your LC-ANS-12 score and recommends personalized stimulation parameters for vagus nerve therapy.
Long-term Case Memory
Persistent knowledge graph remembers your history, labs, medications, and patterns — so you never start from scratch.
Spike Protein Research Library
Curated peer-reviewed database on spike protein pathology, Long COVID mechanisms, and treatment approaches.
For Individuals & Clinicians
Whether you are a patient tracking recovery or a clinician seeking data-driven insights — Omer AI supports both.

"I went from running marathons to barely walking up the stairs. Doctors told me it was anxiety — for three years. After 8 weeks with S2Y, I returned to work and started living again."
