Tortus
Regulated ambient voice AI for NHS clinical documentation with hallucination removal and UKCA Class IIa certification.
For NHS trusts and GP practices using X-On, Tortus is the safest, most proven ambient voice AI available, backed by peer-reviewed hallucination removal data and UKCA Class IIa certification. The 2026 MHRA deregulation makes Class IIa the clearest procurement standard, strengthening its position. However, its NHS-specific focus means private or non-UK clinics should look elsewhere, such as Abridge or Nuance DAX, which offer broader geographic coverage.

About Tortus
Tortus is an ambient voice AI platform built specifically for the NHS. It listens to patient consultations and drafts structured clinical notes, letters, and referrals in seconds, reducing administrative burden on clinicians. Designed for high-volume settings like A&E, outpatient clinics, and mental health services, Tortus is already used in 50+ clinical settings across the NHS, with over 2.5 million consultations captured to date. The platform's core safety engine, The Shell, verifies every generated statement against the original audio and removes anything unsupported before a clinician sees it. Live metrics show 93% of detected hallucinations are auto-removed, and peer-reviewed research in npj Digital Medicine reports a 92.7% reduction in major hallucinations. Zero patient audio is retained at rest, by design. Tortus is the first ambient voice technology certified as a UKCA Class IIa medical device, holding ISO 13485, ISO 27001, Cyber Essentials Plus, NHS DTAC, and DSPT compliance. It integrates with major NHS EPR systems like Epic and Medicus, plus telephony platforms such as X-On Surgery Connect and Avaya, with a custom SDK for new integrations. Evidence from NHS England's Phase IV evaluation shows a 13.4% A&E productivity boost, 23.5% more direct patient care time, and 5 minutes saved per outpatient encounter. For NHS trusts and GP practices that need a regulated, proven solution, Tortus is the most validated option. Non-UK or private clinics without NHS integrations should consider alternatives.
Behind the Verdict
Tortus is purpose-built for the NHS, and that focus shows in every layer. Its standout feature is The Shell, a proprietary safety engine that verifies each generated statement against the original audio and removes unsupported content before clinician review. This directly addresses the biggest fear with AI scribes: hallucinations. The published metrics are strong — 93% of detected hallucinations auto-removed in live use, and a 92.7% reduction in major hallucinations per peer-reviewed research in npj Digital Medicine. The platform's integration with NHS EPR systems (Epic, Medicus) and telephony (X-On Surgery Connect, Avaya) is a practical advantage. The custom SDK allows trusts to build bespoke integrations, which is rare among competitors. The UKCA Class IIa certification is a significant differentiator, especially after the 2026 MHRA deregulation, making it the clearest procurement standard for buyers. The Trust Centre provides transparency with published policies, sub-processors, and pen-test results. However, Tortus is not for everyone. It is tightly coupled to NHS workflows and UK data protection standards, so non-UK practices will find little value. Pricing is not public — you must contact sales for a demo, which can be a barrier for small practices. There is no autonomous mode; clinician approval is always required for write-back, which adds a step. Compared to general-purpose AI assistants, Tortus offers specialized, regulated value for NHS clinicians. Its productivity gains are documented in real evaluations, not just testimonials. For its intended audience, it's a strong, defensible choice.

Real-world workflow fit
Concrete scenarios for the personas Tortus actually fits — and what changes day-one when you adopt it.
You deploy Tortus via X-On Surgery Connect. During each consultation, Tortus captures and drafts the clinical note. After the consultation, you review the note, approve it, and it writes back to the EHR.
Outcome: You reduce your documentation time significantly, freeing up time for more patients or personal admin. The 5 minutes saved per outpatient encounter applies directly.
You implement Tortus in the emergency department. Tortus records consultations, drafts structured notes, flags potential hallucinations with The Shell, and you approve the final note before it enters Epic.
Outcome: You save 47 minutes back per shift, see one more patient per shift, and increase department productivity by 13.4%, as evidenced by the NHS England Phase IV evaluation.
You are evaluating ambient voice technology. Tortus's The Shell safety engine and UKCA Class IIa certification provide evidence of safety. You pilot it in one clinic, integrating via the custom SDK with your EPR (e.g., Medicus).
Outcome: After a successful pilot, you scale to more settings, seeing reduced admin burden for clinicians and no retained patient audio at rest, meeting your data protection requirements.
Use Cases
- GP consultation note-taking
- Emergency department documentation
- Ambulance clinical hub triage documentation
- Reducing clinician administrative burden
- Integrating AI scribe into Medicus workflow
Limitations
- Tortus is designed specifically for the UK NHS, with integrations for NHS EPR systems, limiting applicability outside that context.
- Pricing is not publicly disclosed, requiring contact for a demo.
- Productivity gains from NHS evaluations may not generalize to all environments.
- Clinician approval is required for EHR write-back, adding a verification step.
- As of the 2026 MHRA deregulation, buyers must assess AVT products more heavily, though Class IIa remains the clearest standard.

Setup time & first value
How long it actually takes to get something useful out of Tortus — broken out by persona, not the marketing-page minute.
For GP practices using X-On: setup is turnkey, likely within a week, as it's a native integration. For NHS trusts with Epic or Medicus: integration may take 4-8 weeks, depending on customization. For other EPRs, using the custom SDK could extend to 2-3 months.
