Tortus
NHS-trusted ambient voice AI with 93% hallucination removal for clinical documentation.
For NHS trusts and GP practices, Tortus is the safest ambient voice AI choice. The Shell hallucination detection is a genuine safety differentiator, backed by peer-reviewed evidence and live at scale. Non-UK or private practices without NHS integration should look elsewhere.
- NHS trusts seeking ambient voice AI with proven A&E and outpatient productivity gains
- GP practices using X-On who want to reduce documentation burden
- Clinicians in high-volume settings (A&E, ambulance hubs) needing to save time per consultation
- NHS organisations requiring a regulated medical device with published safety data
- Private practices outside the UK or not connected to NHS systems
- Clinics needing a general-purpose AI assistant with non-clinical features
- Organisations requiring multi-language or multilingual ambient voice support

Skip Tortus if you are a non-UK clinic or a private practice not connected to NHS systems, as its integrations and regulatory status only serve the UK public healthcare environment.
Custom pricing means small GP practices may find the cost prohibitive without a published tier to compare against.
Tortus uses contact-only pricing tailored for NHS trusts, making cost transparency low. Compared to generic AI scribes (e.g., Otter.ai, Fireflies.ai) which offer self-serve tiers from $10–30/mo, Tortus is likely more expensive but provides regulated clinical safety and EHR integration that those tools lack. For NHS buyers, the value is in proven productivity gains and regulatory compliance rather than upfront price.
In short
Tortus — NHS-trusted ambient voice AI with 93% hallucination removal for clinical documentation. Best for NHS trusts seeking ambient voice AI with proven A&E and outpatient productivity gains, GP practices using X-On who want to reduce documentation burden, Clinicians in high-volume settings (A&E, ambulance hubs) needing to save time per consultation.

About Tortus
Tortus is a regulated ambient voice AI clinical assistant purpose-built for the NHS. It automatically generates structured clinical notes, letters, and referrals from patient consultations, letting clinicians focus on patients rather than typing. Live across 1,000+ NHS organisations and capturing over 2.5 million consultations, Tortus integrates with major NHS EPR systems (Epic, Medicus) and telephony services (X-On, Avaya). Its key differentiator is The Shell, a proprietary clinical safety system that detects and removes hallucinations from generated notes. Independent evaluation in npj Digital Medicine showed a 92.7% reduction in major hallucinations; as of January 2026, the Shell auto-removes 93% of detected hallucinations, boosting hallucination-free notes from 34% to 86%. Proven in large-scale NHS trials: +13.4% A&E productivity boost (NHS England Phase IV), +23.5% more direct patient-care time, and 5 minutes saved per outpatient encounter. Tortus is the first ambient voice technology certified as UKCA Class IIa medical device, ISO 13485 certified, and compliant with NHS DTAC and DSPT standards. Compared to general-purpose AI scribes, Tortus offers NHS-specific integration and published safety data.
Behind the Verdict
Tortus is not a generic AI scribe—it's a medical device. If you're an NHS trust or a GP practice using X-On, this is the ambient voice tool with the strongest safety case. The Shell hallucination detection, now auto-removing 93% of hallucinations, is a hard technical moat. The published figures—13.4% A&E productivity, 5 minutes saved per outpatient—are real-world results, not lab demos. Tortus produces structured notes, letters, and referrals in seconds, and integrates natively with Epic, Medicus, and X-On telephony. The downsides? It's NHS-only. Private clinics outside the UK or those not on NHS EPRs can't use it. It also requires clinician approval before write-back—autonomy fans may find that slow. If you're a US hospital, look at Nuance DAX or Abridge. But for the NHS, Tortus has the certifications, the integrations, and the evidence. We'd pick it for any NHS organisation that wants to reduce documentation burden without compromising safety.

Real-world workflow fit
Concrete scenarios for the personas Tortus actually fits — and what changes day-one when you adopt it.
During a consultation, Tortus automatically captures and diarises the conversation via X-On, generates a structured note with suggested clinical codes, and the GP reviews and approves before it writes back to the EHR.
Outcome: GP saves 5 minutes per encounter, reduces after-hours admin, and maintains eye contact with the patient.
Tortus captures audio in the emergency department, generates a clinical note and referral letter, flags any hallucinations via The Shell, and the consultant approves the note for direct write-back to Epic.
Outcome: 47 minutes saved per shift, +13.4% patient throughput, and reduced documentation errors.
Use Cases
- GP consultation note-taking
- Emergency department documentation
- Reducing clinician administrative burden
- Integrating AI scribe into Medicus workflow
- Ambulance clinical hub triage documentation
Limitations
- Tortus is currently focused on the UK NHS—its applicability elsewhere is limited.
- Pricing is custom and not publicly disclosed, which may deter small practices.
- Efficiency gains reported are based on internal studies and may vary by setting.
- Clinician approval required for EHR write-back adds a step.

Where the pricing makes sense
The company stage and team size where Tortus's pricing actually pencils out — and where peers do it cheaper.
Tortus uses contact-only pricing tailored for NHS trusts, making cost transparency low. Compared to generic AI scribes (e.g., Otter.ai, Fireflies.ai) which offer self-serve tiers from $10–30/mo, Tortus is likely more expensive but provides regulated clinical safety and EHR integration that those tools lack. For NHS buyers, the value is in proven productivity gains and regulatory compliance rather than upfront price.
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 NHS trusts already using supported EHRs (Epic, Medicus) or telephony (X-On, Avaya), initial setup typically takes a few weeks, including integration testing and staff training. GPs using X-On can activate Tortus through the existing partnership, with first value in under a month. New custom SDK integrations may take longer, depending on the trust's IT resources.
Switching to or from Tortus
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From manual dictation or typing: Tortus replaces the need for direct note entry by auto-generating structured notes from consultations, reducing time spent on documentation.
- →From generic AI scribes: Tortus offers NHS-specific integration, hallucination safety, and regulatory compliance, requiring trust-level onboarding rather than individual sign-up.
- ↗To another NHS-registered AI scribe: Export consultation notes via standard EHR export tools; Tortus stores no patient audio.
- ↗To manual processes: EHR notes remain in the system; clinicians can revert to typing or dictation without data loss.
