Tandem Health is a European clinical AI platform focused on documentation and EHR transfer. It transcribes patient visits and sends structured notes directly to systems like Epic, Cerner, and various European health records through its One-Click EHR Transfer feature.
Both Tandem and Heidi serve the European market and offer AI-powered scribes. This article compares the two across features, specialties, language support, EHR connectivity, compliance, pricing, and hardware to help you decide which fits your clinical workflow.
Tandem’s main selling point is EHR integration. Heidi offers the same connectivity to your EHR workflows while addressing the practical, document-heavy realities of clinical work. Documentation goes from the visit to the patient file with minimal manual entry.
Both Tandem and Heidi offer scribes to reduce administrative burden. However, based on publicly available information, Tandem's documentation output appears limited to structured note transfer and may not adapt to specialty-specific clinical language.
Heidi’s utility is designed to generate the full suite of clinical paperwork, including referral letters and patient summaries. Heidi Evidence surfaces cited clinical knowledge from trusted sources during the visit, with verbatim excerpts so you can verify the source before using it. Tandem does not offer an equivalent feature.
The adoption of ambient AI technology directly addresses the primary driver of clinical burnout: administrative burden. Studies show ambient AI scribes cut documentation time by 30 to 60 minutes per provider per day. Research from Yale School of Medicine found this also reduced physician burnout and improved patient engagement.
Multidisciplinary clinics need AI that adapts to the way clinicians write. The customizability ensures that the clinician-approved final note keeps their unique voice and meets medical regulatory and safety standards.
Watch to learn about Heidi Remote and how clinicians stay connected, document with ease, and deliver care from anywhere.
Practitioners assess AI tools by how reliably they reduce the cognitive and administrative load of clinical work. Comparing the two tools shows how clinical AI has moved beyond documentation into fuller workflow support. That comparison starts with what each tool actually does day-to-day.

Tandem's core features are scribe and medical coding, with a focus on EHR transfer. Heidi covers Scribe, Evidence, Forms, and Tasks, extending beyond documentation into clinical knowledge retrieval and dictation across every application you work in.
Heidi adds a dedicated device called Remote. It keeps audio consistent in various settings. The note Scribe generates reflects what was said, not what you remembered to type later.
Tandem Health performs well in high-volume primary care environments and supports a wide range of medical needs, spanning over 50 specialties.
Heidi covers over 200 specialties, including high-complexity settings like surgery and emergency, where note structure varies between cases. Coverage also includes veterinary medicine, which shows Heidi’s range isn’t limited to human clinical practice.
Tandem Health AI Scribe saves clinicians up to 14 hours per week while Heidi supports clinicians for an average of 17.6 hours weekly.
Tandem can quickly generate notes and offers specialized medical coding, but it relies on a nearby phone or laptop. In busy clinics, this means that the microphone cannot pick up what it needs to. Distance, room noise, or unstable WiFi can lead to lost context and inconsistent documentation quality.
Heidi addresses all of those problems with audio with Remote. Clinicians receive consistently clear audio reception as they move between rooms or work offline.
Heidi stands out for its robust commitment to compliance, covering major international and regional standards. This includes adherence to ISO 27001, GDPR, NHS, HIPAA, and notably, ISO 42001.
The ISO 42001 certification is specifically for health technology providers, guaranteeing the responsible development, deployment, and management of AI systems. Furthermore, its compliance with GDPR is key to upholding individual privacy rights and enforcing stringent data handling protocols.
Tandem AI Scribe is also compliant with GDPR and certified with ISO 27001 and is NHS-compliant. Its certifications focus on European data residency requirements.
For teams prioritizing data sovereignty, retention controls, and responsible AI governance, Heidi provides broader compliance coverage across global healthcare environments.
Tandem Health App is available via web. It can also be accessed via mobile and has its own Tandem Conference Microphone.
Heidi’s multi-capability platform is accessible with web, desktop, mobile and a dedicated microphone to keep everything connected. With Heidi, clinicians document between sessions without major interruptions.
Heidi distinguishes itself by offering Heidi Remote, a wearable device that ensures quality audio documentation even during long days in noisy clinics. These are the conditions where software-only tools struggle to maintain note quality.
Tandem AI Health can instantly generate notes in a chosen language. Its language support anchors on European regional localization. However, the exact number of supported languages is not publicly listed.
In contrast, Heidi takes a more transparent and global approach, having the ability to transcribe and document in over 110 languages. It detects language mid-session and supports encounters in multiple languages.
Tandem AI connects with systems such Medical Office, x.concept and x.isynet. Its workflow is centered on documentation and traditional administrative patterns.
Heidi connects to EHR systems including Athenahealth, MediOffice, x.concept, and x.isynet, with a growing list across regions.
Where Heidi differs is in what travels alongside the note: Evidence, coding support, and follow-up document generation all sit within the same workflow, so the EHR connection is one step in a broader clinical process rather than the endpoint.
Tandem Health is optimized and used across European primary clinical systems. However, some regional pilots report adoption rates of around 35%.
In contrast, Heidi consistently achieves a 60-80% adoption rate globally, driven by its clarity and flexibility. Individual clinicians and care teams who value a tool that adapts to their needs drive Heidi’s growth.
Both platforms offer a free tier, but the coverage is different. Heidi's free tier includes unlimited transcription, unlimited notes with standard templates, unlimited Evidence queries with citations, and 10 pro actions per month. Basic Dictate is included for these users.
You can try Heidi’s enhanced features, like advanced templates, before upgrading. Tandem's free tier caps at 10 conversations per day.
On paid plans, Heidi's Clinician plan is £55 per month, and the Practice tier is custom pricing. Tandem's paid tier includes unlimited note generation, two custom templates, and invitations for two co-workers.
On hardware, Heidi offers its Remote, a wearable microphone built for all-day clinical use across various settings. Tandem sells a conference microphone for £40. Heidi’s Remote moves with you, while a conference microphone stays in the room.
The free tier gap is the clearest differentiator. Heidi gives you unlimited transcription and Evidence queries with no daily cap. Tandem limits you to 10 conversations per day. For a clinician testing both tools, Heidi's free tier covers a full day of documentation while Tandem's runs out before lunch in a busy clinic.
Heidi holds a 5/5 on G2 compared to Tandem Health’s 4.7/5, which are strong ratings.
Heidi reviewers frequently cite its adaptability across specialties and how closely notes match their documentation style. Tandem reviewers praise its speed in primary care note generation, though some flag a steeper learning curve and manual data entry during initial setup as friction points.
Where clinicians see the difference is in scope. Tandem focuses on getting the note done. Heidi covers the note, the evidence lookup and the follow-up documents from the same visit.
Heidi is your AI care partner helping clinicians like you to lighten documentation load. It auto-generates clinical notes based on your preferred templates and has a multi-product suite including:
Evidence: Identify, manage and verify clinical information efficiently with its built-in source checking and citation.
