What TORTUS AI does
TORTUS AI is a UK-based clinical AI company that has built an ambient voice technology platform for clinical documentation, founded in November 2022 by NHS doctors and engineers at Entrepreneur First. Its core product captures multi-speaker audio from clinician-patient consultations, transcribes it, and uses generative AI to produce structured clinical notes, letters, referrals, and SNOMED clinical codes that are written back into the patient's EHR record. The Shell, a proprietary clinical safety system launched in January 2026, detects and automatically corrects hallucinations in generated notes, achieving a 92.7% removal rate in production and lifting hallucination-free notes from a 34% baseline to 86% across 150,000+ consultations.
The platform is the first ambient voice technology registered as a UK Class I medical device with the MHRA (November 2024), is ISO 13485 and ISO 27001 certified, and is DTAC and DSPT compliant. TORTUS integrates natively with Epic and Oracle Health (Cerner), with SDK-based paths into EMIS, TPP SystmOne, Access Rio, and partner EHRs including Medicus, X-on Health (reaching 3,500+ GP surgeries), Limbic, and Ortivus. The company's go-to-market combines direct enterprise sales to NHS trusts (procurable via G-Cloud 14 and DPS/RM6200), a partner SDK programme with per-audio-hour usage pricing, and product-led growth into primary care via X-on Surgery Connect. Customers include Royal Devon University Healthcare, London Ambulance Service, St George's University Hospitals, Great Ormond Street Hospital, Somerset NHS FT, Kingston Hospital, and UCLH, with NHS England Phase IV evaluation results (17,000+ patients across 9 sites) referenced in the NHS Ten Year Plan. The company has raised approximately $4.2M in seed funding led by Khosla Ventures and is privately held.

TORTUS AI product offering
Product offeringCore offering
TORTUS AI builds an ambient voice technology platform that captures multi-speaker clinical consultations, transcribes them, and generates structured clinical notes, letters, referrals, and SNOMED codes which are written back into the EHR. It is registered as a UK MHRA Class I medical device and includes "The Shell," a proprietary clinical safety system that detects and corrects hallucinations in AI-generated notes. The platform is sold directly to NHS Trusts on a per-clinician annual licence and licensed to healthcare technology partners via a JavaScript SDK on a per-audio-hour basis.
Product overview
TORTUS AI offers a unified ambient voice clinical documentation platform built around its core TORTUS product — an MHRA Class I-registered medical device that captures multi-speaker audio from clinical consultations and generates structured clinical notes, letters, referrals, and clinical codes. The platform is extended by The Shell, a proprietary clinical AI safety system that detects and automatically corrects hallucinations in generated notes, achieving a 92.7% removal rate. Three usage modes — Ambient Note (core), Meeting Mode (for MDTs and huddles), and Dictation (legacy replacement) — serve different clinical workflows, alongside Template Customisation and Data Insights modules. The TORTUS SDK enables third-party healthcare software vendors to embed the ambient voice widget inside their own EHR products (Epic, Oracle Health/Cerner, EMIS, TPP, Access Rio, Medicus, X-on, Avaya), inheriting the Class I medical device and The Shell's safety capabilities. Pricing is per audio hour with volume tiers, and free trial hours are available.

TORTUS AI competitors and assessment
Company assessmentDirect peers
- Abridge: US-based ambient AI scribe that generates structured clinical notes from doctor-patient conversations and writes them back to the EHR. Directly comparable to TORTUS in product, customer base (large hospital systems), and pricing model, though operating at much larger scale in the US market.
- Nabla: Ambient AI assistant for clinicians producing structured notes and medical codes from consultations. Comparable to TORTUS in core functionality and target user, with a similar focus on EHR write-back and multi-specialty support.
- Suki AI: AI voice assistant for clinicians that generates notes and dictations across multiple EHR systems and specialties. Overlaps directly with TORTUS on ambient documentation and EHR integration breadth.
- Commure (including Augmedix): Healthcare technology platform following its acquisition of Augmedix, offering ambient AI documentation and clinician workflow tools. Comparable to TORTUS in ambient-scribe focus and large health-system customer base.
- Ambience Healthcare: Ambient AI platform for clinical documentation and coding, deployed across large US health systems. Direct competitor on ambient note generation, EHR integration, and specialty-specific customisation.
- DeepScribe: Ambient AI medical scribe that captures patient-provider conversations and generates notes directly into the EHR. Comparable to TORTUS in core use case, target clinician customer, and EHR write-back workflow.
- Notable: Ambient AI platform automating clinical documentation, scheduling, and patient outreach for health systems. Overlaps with TORTUS on ambient note generation and EHR-integrated workflows for hospital customers.
Broad incumbents
- Microsoft DAX Copilot (Nuance): Microsoft-owned ambient AI documentation product built on Nuance's Dragon platform, bundled with Microsoft Cloud for Healthcare and integrated with Epic and other EHRs. Represents a major incumbent threat to TORTUS as ambient AI becomes a feature of broader EHR and productivity suites.
Emerging players
- Heidi Health: AI medical scribe generating clinical notes and letters from patient consultations, with growing presence in the UK and Australia. Comparable to TORTUS in functionality but with less depth of NHS-specific regulatory positioning and integrations.
- Eleos Health: Behavioural-health-focused ambient AI scribe that captures sessions and produces progress notes. Comparable to TORTUS's meeting and mental-health use cases (e.g., Limbic partnership) but narrower in clinical scope.
