Healthcare has no margin for error.

The dangerous truth is that most AI medical scribes make mistakes. We are dedicated to removing those risks to patient safety.

That's why we built The Shell.

TORTUS' proprietary clinical safety system, designed to meticulously moderate and regulate our services on a constant basis — catching rare errors before they reach clinicians.

01 / DETECT

Caught instantly, not discovered later.
Every statement is checked the moment it is drafted.

02 / VERIFY

Validated against the source context.
Each claim is held up against the consultation itself.

03 / REMOVE

93.1% of hallucinations removed before the note is complete.
Unsupported content is corrected before a clinician ever sees it.

A living safety standard.

While others rely on hoping their models improve, we've built a system that ensures clinical safety through continuous validation. The Shell runs across every output, every time.

Chief Complaint

Acute migraine

History of Present Illness

34-year-old female presents to ED with severe frontal headache, photophobia, and nausea. Onset approximately 3 hours prior to arrival. Pain described as throbbing, rated 8/10.

Medications Administered

Sumatriptan 100mg PO

Patient reported significant symptom relief within 45 minutes of medication administration. Pain decreased to 2/10.

Vital Signs

Assessment

Acute migraine, responsive to treatment
Discharged home with migraine precautions. No adverse reactions observed.

Unrivalled safety.

Even a "2% error rate" can be unsafe when every note touches real patients. The Shell is engineered to close that final gap.

We ran a comparative analysis against other clinical documentation AI systems. Using a controlled set of 50 general-practice consultations, we generated notes in the standard SOAP format across multiple platforms.

Hardening The Shell: taking AI safety from detection to action

How we built an end-to-end hallucination detection and correction pipeline that automatically removes 93% of detected hallucinations, increasing hallucination-free notes from 34% to 86% in production.
