I built this because I could. Most patients in my situation cannot.
I am giving it to you so they do not have to.

What No Health AI Product Does

Every health AI company does the same thing: summarize records within one hospital network. Surface billing codes. Flag drug interactions from a static list. None of them do this.

482 Queries, 8 Domains, 13 Outcomes

Each row is a gap that persisted for months or years. A Sonar API query connected documented symptoms to published evidence. A doctor acted.

Gap in Care What the System Detected What Happened
Cortisol 80 nmol/L never retested in 28 months Post-HSCT endocrinopathy prevalence: 80% within 2 years. TSH alone misses central hypothyroidism. Cortisol and ACTH ordered. Critically low confirmed.
GVHD graded "mild" with 3 organs involved NIH 2014 criteria require moderate minimum for 3 organs. Scores changed without examinations. Reclassified. Ruxolitinib started.
DLCO never checked despite anthracycline exposure BOS screening requires serial DLCO, not just spirometry. DLCO dropped 89% to 67%. BOS in 26.1% of lung volume.
ALAT 375 U/L uninvestigated for 20 months Post-HSCT viral reactivation literature. Hepatitis E in immunosuppressed patients. Hepatitis E diagnosed on stored serum.
Cardiac MRI never ordered despite idarubicin, ferritin 1247, tachycardia Cardiac late effects after anthracycline exposure. Ferritin above 1000 as cardiac iron loading. Diffuse myocardial edema. Lake Louise criteria met. LVEF 50.5%.
Brain MRI not ordered despite prolactin elevation, testosterone collapse Post-HSCT CNS screening. Pituitary iron deposition after transfusion-dependent disease. 33 white matter lesions. 5.1x age-normal volume. Bilateral pallidal iron.
No autonomic testing in 26 months IST diagnostic criteria. Post-HSCT dysautonomia. NIH 2022 cGVHD Task Force. Oura data: RMSSD 8.7 ms. 94.4% below ESC threshold.
Testosterone ordered, never drawn for 14 months Post-HSCT gonadal failure prevalence after myeloablative conditioning. 34.2 to 15.2 to 12.4 nmol/L. Collapsing.
21,188 contradictions detected across 17 institutions 3,648 cross-institutional · 13 guideline violations against EBMT and NIH standards

Second Patient - Zero Configuration

A second patient sent his records. 55 documents from an Australian childhood leukemia survivor. 10 critical gaps found in 10 minutes. Zero configuration.

Patient 1 - Norway

Post-HSCT, 65 providers

Blood cancer diagnosis at 33. Stem cell transplant November 2023. 26 months getting worse while 17 institutions said it was psychological.

482 Sonar queries across 8 domains in 56 days. 13 clinical outcomes. 5 international centers accepted the case.

Patient 2 - Australia

Childhood leukemia survivor

Age 36. Leukemia at 14. Bilateral vertebral artery dissection with cerebellar stroke at 33. No cancer survivorship screening in 22 years.

The system analyzed everything in 10 minutes. The echocardiogram that was never done is being ordered. The survivorship screening that never happened is starting.

55 Documents

10 Gaps Found

Two patients. Two countries. Two diseases. Same result: symptoms documented, workup never done, system found the gaps.


328 Queries Built a Variant Classification Pipeline

Perplexity identified the key papers, mapped mutation databases, and validated variant classification tools. The pipeline reclassified a variant of uncertain significance to pathogenic.

80.9% ClinVar Concordance
0 Variants Benchmarked
7.7 × 10-13 Expected Frequency
Gene Variant ESM-2 Score ACMG PP3 Interpretation
DNMT3A R882H -8.383 PP3 Strong Hotspot in AML/MDS, disrupts catalytic domain
SETBP1 G870S -9.804 PP3 Strong SKI homology domain, disrupts degron motif
EZH2 V662A -2.966 PP3 Supporting SET domain loss-of-function. Reclassified VUS to Pathogenic.
PTPN11 E76Q -1.865 PP3 Supporting N-SH2 domain, disrupts autoinhibitory interface
IDH2 R140Q -1.478 PP3 Benign/VUS Gain-of-function oncometabolite. ESM-2 captures disruption, not gain.

ClinVar submission SUB16087716. EZH2 V662A reclassified from VUS to Pathogenic. Zero PubMed hits for this specific variant. Perplexity identified Chase et al. 2020 establishing EZH2 SET domain loss-of-function.

ISMB 2026 Abstract #623 submitted. VarI track, flagship bioinformatics conference. 80.9% ClinVar concordance on 284 variants from 40 independent GENIE profiles. Zero false positives.

26,642 myeloid patients searched across 12 international databases. Zero matches for this mutation combination.

Tazemetostat contraindication predicted computationally. The drug was withdrawn globally on March 9, 2026.


Interactive Cardiovascular Digital Twin

Built on Oura Ring data. 13 analysis modules, 99,300+ biometric readings. Detected ruxolitinib response in 3 days (p=0.018). Predicted GVHD flare 31 days ahead.
