AI Medical Scribe Comparison 2026 — Heidi vs Lyrebird vs Tortus vs Abridge vs Suki vs DAX
A clinician's side-by-side guide to the six AI scribes Australian, UK, US, and Canadian practitioners are actually using in 2026. Data residency, regulatory fit (Privacy Act, HIPAA, GDPR), specialty support, pricing, and which one fits which practice.
Quick answer
No single AI medical scribe is best globally. The right choice depends on your jurisdiction, practice type, and the regulatory framework you need to satisfy:
- Australia + New Zealand: Heidi (largest market share, broadest workflow) or Lyrebird (leaner, solo-practice). Both AU-resident, Privacy Act-compliant by default.
- United Kingdom: Tortus or Tandem (on NHS England's Ambient Voice supplier registry). Heidi UK is a credible alternative for private practice.
- United States: DAX Copilot (Microsoft Nuance — dominant in hospital systems), Abridge (gaining in primary care), Suki (mid-tier ambient). Heidi US is the newer entrant.
- Canada: Heidi has strong Canadian presence; Abridge and DAX also operate. Provincial colleges accept self-claim CPD with any compliant tool.
- ChatGPT, Claude.ai, Gemini: NOT clinical scribes. General-purpose LLMs, no jurisdiction-appropriate data residency by default. Use only for non-PHI clinical writing.
The six AI medical scribes clinicians are actually using in 2026
Every one of these is a Tier A healthcare-purpose-built tool — designed for clinical documentation from the ground up, with regulatory compliance built into the workflow. They are not general-purpose LLMs with a clinical wrapper.
1. Heidi Health (AU founded; now AU, UK, US, NZ, CA)
- Headline: Founders publicly state roughly half of Australian GPs use Heidi. Now expanding into allied health and across the UK, US, NZ and Canada with regional data residency.
- Specialty support: Strong AU clinical conventions (SOAP, problem-orientated, NDIS-aligned, mental health care plans, allied health, GP). Expanding US/UK templates.
- Integrations: Broad — Best Practice, MedicalDirector, Genie, Bp Premier (AU); various UK + US practice-management platforms.
- Privacy posture: AU data residency by default; US/UK regional residency available; HIPAA BAA available for US customers.
- Best for: Larger practices, broad specialty mix, clinicians who want comprehensive workflow customisation.
2. Lyrebird Health (AU founded; AU primary)
- Headline: Smaller market position than Heidi but well-regarded in solo and small-group practices. Australian-built, AU data residency.
- Specialty support: Strong AU clinical templates; leaner customisation surface.
- Integrations: Focused integration set; sufficient for typical solo practice.
- Privacy posture: AU data residency by default. Privacy Act compliant.
- Best for: Solo practitioners and small clinics who value speed and simplicity over template depth.
3. Tortus (UK; NHS-focused)
- Headline: One of 19 vendors on NHS England's Ambient Voice supplier registry (January 2026). Trialled at Great Ormond Street Hospital with published outcomes data.
- Specialty support: UK clinical conventions, NHS coding (SNOMED CT integration), GP and secondary-care templates.
- Integrations: EMIS Web, SystmOne, NHS Spine compatibility paths.
- Privacy posture: UK data residency. NHS information governance compliant. GDPR-compliant by default.
- Best for: NHS clinicians and UK private practice that needs NHS-side integrations.
4. Abridge (US; primary care + outpatient)
- Headline: Fast-growing US ambient scribe with strong primary-care adoption. Backed by major US health systems including UPMC and Kaiser.
- Specialty support: US clinical conventions, ICD-10, CPT coding integration, US insurer documentation requirements.
- Integrations: Epic, Cerner, Athenahealth EHR integrations.
- Privacy posture: HIPAA BAA standard. US data residency. SOC 2 Type II compliant.
- Best for: US primary care, outpatient specialties, mid-size health systems.
5. Suki (US; physician documentation)
- Headline: Voice-first US ambient scribe, longer in market than Abridge. Used across primary care, internal medicine, specialty practices.
- Specialty support: US clinical templates across most specialties; physician-focused (less allied-health emphasis).
- Integrations: Epic, Cerner, eClinicalWorks, Athenahealth.
- Privacy posture: HIPAA BAA, US data residency.
- Best for: US physicians wanting a mature, physician-tuned scribe.
6. DAX Copilot (Microsoft Nuance; US + UK)
- Headline: Dragon Ambient eXperience, now branded DAX Copilot under Microsoft. The dominant enterprise scribe in large US hospital systems. Available in the UK via Microsoft's healthcare partnerships.
- Specialty support: Broadest coverage of any scribe — physicians, nursing, allied health, multi-specialty hospital workflows.
- Integrations: Native Epic + Cerner; Microsoft cloud integrations.
- Privacy posture: HIPAA, HITRUST, ISO 27001. Microsoft enterprise security stack. UK NHS-compliant configurations available.
- Best for: Large US health systems already on Microsoft + Epic/Cerner; enterprise UK deployments.
Side-by-side comparison
| Tool | Primary market | Data residency | Regulatory fit | Best for |
|---|---|---|---|---|
| Heidi | AU primary; now UK/US/NZ/CA | Regional (AU, US, UK, etc.) | AHPRA, HIPAA BAA, NHS-compatible | Broad workflow, multi-specialty, allied health |
| Lyrebird | AU primary | AU | Privacy Act (APP 8 compliant by default) | Solo practitioners, small clinics |
| Tortus | UK (NHS) | UK | NHS IG Toolkit, GDPR, Ambient Voice registry | NHS clinicians + UK private practice |
| Abridge | US | US | HIPAA BAA, SOC 2 Type II | US primary care, outpatient, mid-size systems |
| Suki | US | US | HIPAA BAA | US physicians, multi-specialty |
| DAX Copilot | US + UK + enterprise | US (UK regional config available) | HIPAA, HITRUST, ISO 27001, NHS-compatible | Large US health systems, enterprise UK |
| ChatGPT (consumer) | Universal | US | NOT clinical-compliant by default | Non-PHI writing only |
| Claude.ai | Universal | US | NOT clinical-compliant by default | Non-PHI writing only |
| Gemini | Universal | US | NOT clinical-compliant by default | Non-PHI writing only |
Privacy frameworks — what changes between AU, UK, US, Canada
🇦🇺 Australia — Privacy Act 1988 + AHPRA AI Guidelines
Australian Privacy Principle 8 governs offshore disclosure. AU-resident scribes (Heidi AU, Lyrebird) don't trigger APP 8. Consumer LLMs (ChatGPT, Claude.ai) do — explicit patient consent required.
🇬🇧 United Kingdom — UK GDPR + NHS Information Governance
UK GDPR requires lawful basis + appropriate safeguards. NHS England's Ambient Voice supplier registry is the practical gate — using a registered scribe is the path of least resistance. GDPR offshore-transfer rules apply to US-only tools.
🇺🇸 United States — HIPAA + State-by-State
HIPAA Business Associate Agreement is the contractual mechanism. Every clinical scribe must have a signed BAA. Without it, the tool is not HIPAA-compliant regardless of marketing claims. Consumer LLMs do not sign BAAs by default.
🇨🇦 Canada — PIPEDA + Provincial Privacy Acts
PIPEDA covers federal commercial entities. Provinces (Ontario PHIPA, BC PIPA, Alberta HIA) add local rules. Cross-border data flows require notice + safeguards. Tools with Canadian data residency simplify this materially.
Which AI scribe should you pick — by jurisdiction + practice
Australia & New Zealand:
- Larger practice, multi-specialty: Heidi
- Solo or small clinic: Lyrebird
- Allied health (physio, osteo, etc.): Heidi has broader allied-health template depth
- NDIS-heavy practice: Either Tier A scribe with the audit-safe documentation workflow (see our ChatGPT NDIS reports article)
United Kingdom:
- NHS: Tortus or Tandem (Ambient Voice registry) — start here
- UK private practice: Heidi UK or Tortus, depending on integration needs
- Multi-site / hospital trust: DAX Copilot if already on Microsoft + Epic
United States:
- Solo or small primary care: Abridge or Suki
- Mid-size system: Abridge (Epic integration depth) or DAX Copilot
- Large hospital system already on Microsoft + Epic: DAX Copilot
- Allied health / specialty: Heidi US is the emerging option; Abridge has weaker allied-health templates
Canada:
- Family medicine + outpatient: Heidi CA or Abridge (US tools work but check provincial cross-border rules)
- Hospital system: DAX Copilot (most enterprise deployments)
When NOT to use ANY AI scribe — universal across jurisdictions
Switch off the AI scribe regardless of tool choice for: mental health disclosures, mandatory reporting (child safety, family violence, elder abuse), complex medicolegal cases, paediatric consults with mixed consent, patients who decline AI use, sensitive sexual/reproductive health consults, and any situation where transcript accuracy matters more than note-writing speed.
