What Is Heidi Health?

Heidi Health is an AI-powered medical scribe founded in 2019 in Melbourne, Australia by Dr. Thomas Kelly (vascular surgical resident), Waleed Mussa, and Yu Liu. Originally called Oscer, the company rebranded to Heidi Health in 2021 and has since grown into one of the more widely used AI scribe platforms globally (MobiHealthNews, 2025).

What Heidi Does

Heidi listens to patient-provider conversations, transcribes them, and generates structured clinical notes. Key features include:

Clinical note generation: SOAP notes, H&P, progress notes, DAP notes, pre/post-op reports, session summaries
Referral and patient letters: Auto-generated from consultation data
Custom templates: Hundreds of pre-built templates across 200+ specialties, plus custom template creation
Ask Heidi: An in-app AI assistant for editing notes, retrieving billing codes, and performing calculations
Dictation mode: Standalone dictation for letters and referrals outside of live consults
Heidi Calls (beta): Automated patient phone calls for appointment reminders, follow-ups, pre-admission checks, and medication reminders
110+ language support: Industry-leading multilingual transcription with auto-detection

What Heidi Does Not Do

Heidi explicitly states it “cannot provide medical advice.” It does not generate differential diagnoses, assessment and plan recommendations, or clinical reasoning. Heidi has introduced an Evidence mode (early access) for clinical Q&A with citations and a Context feature that links up to 3 past sessions, but it does not offer real-time diagnostic insights during encounters or full longitudinal patient context. Heidi is primarily a documentation tool, not a clinical decision support platform.

How Does Glass Health Compare to Heidi Health on Features?

Both platforms start with ambient scribing, but Glass Health adds a clinical decision support layer that Heidi does not offer — real-time clinical insights (differential diagnosis, suggested history questions, and next steps), structured A&P generation, clinical Q&A with citations to clinical guidelines and medical literature, and patient context that persists across visits. The feature comparison below highlights where the two diverge.

What Can Heidi Health Do Well?

Heidi is a widely used AI scribe for good reasons. Here’s what it does well:

Industry-leading multilingual support. Heidi supports 110+ languages for transcription with automatic language detection — far more than any competitor in the AI scribe market. For international practices, multilingual clinicians, or settings where patients speak different languages, Heidi is hard to beat.

Generous free tier. Heidi’s free plan includes unlimited basic note generation with no time limit — one of the most accessible entry points in the market. Pro Actions (referral letters, patient summaries) are capped at 10/month on the free tier, but core scribing is unlimited.

Global reach. Heidi operates across many countries, handling a high volume of patient consultations.

Strong template system. Hundreds of pre-built templates across 200+ specialties, with custom template creation and shared template libraries for teams. The template breadth covers general practice through specialized surgical and mental health workflows.

Heidi Calls. A unique differentiator — automated patient phone calls for appointment reminders, follow-ups, pre-admission checks, and medication reminders. Few competitors offer this.

Cost-effective. At $99/month ($66.60/month annually), Heidi sits at the low end of the AI scribe market. Combined with the free tier, it provides accessible pricing for solo practitioners and small practices.

Strong compliance. HIPAA, SOC 2 Type II, and ISO 27001 certification — a solid security trifecta with regional data sovereignty enforcement.

What Can’t Heidi Health Do That Glass Health Can?

Heidi excels at turning conversations into notes, but documentation is where its capabilities end. Clinicians who need active diagnostic support will find the following gaps significant:

Diagnostic reasoning is off the table. Heidi does not produce differential diagnoses — period. It records what was said and structures it into a note, but it cannot suggest what diagnoses to consider, which conditions to rule out, or what tests to order next. Glass Health generates a tiered DDx during the encounter: Most Likely diagnoses for immediate testing, an Expanded Differential if the initial workup returns negative, and Can’t Miss conditions where delayed diagnosis carries high morbidity. Each tier carries specific next steps, and the DDx evolves live as new information emerges.

Clinical reasoning stays in the clinician’s head. Heidi captures the A&P the clinician speaks aloud but contributes nothing to it. If the physician says “Plan: start metformin,” Heidi writes that down. Glass Health takes the patient’s history, exam findings, and labs and independently generates a problem-based Assessment & Plan — complete with diagnostic next steps, treatment recommendations, and evidence citations drawn from medical literature.

“Cannot provide medical advice” is an explicit policy. Heidi’s own documentation states the platform “cannot provide medical advice.” It will not surface diagnostic suggestions, flag drug interactions, highlight relevant clinical guidelines, or offer treatment considerations at any point during the encounter. Glass Health provides this clinical decision support in real time, delivering actionable insights while the physician is still with the patient.

Ask Heidi’s clinical capabilities are still in early access. The core “Ask Heidi” feature handles requests like “shorten my note” or “add a billing code” — scoped to documentation cleanup and basic calculations. Heidi has introduced an “Evidence mode” (early access) that provides evidence-backed answers to clinical questions with citations from PubMed, Cochrane, CDC, NICE, and RACGP. However, this remains an early-access add-on rather than a fully integrated CDS workflow. Glass Health’s clinical Q&A, structured DDx generation, and A&P with evidence citations are core features available to all users — not early-access additions — and they operate within an integrated clinical decision support workflow that includes real-time diagnostic reasoning during encounters.

Limited continuity between patient visits. Heidi has introduced a “Context” feature that automatically links sessions for the same patient when demographic details match, and clinicians can add up to 3 linked past sessions for reference. However, this requires demographic matching and is capped at 3 prior sessions — it does not provide full longitudinal patient context. Glass Health automatically persists complete patient context across all encounters without manual selection or session limits, so the AI’s reasoning reflects the patient’s full clinical trajectory — not just today’s conversation plus a handful of prior sessions.

No in-encounter diagnostic guidance. While Heidi listens, it only documents. It does not propose differential diagnoses, recommend additional history questions, or flag management considerations during the visit. Glass Health actively contributes clinical input — surfacing DDx updates, prompting questions the clinician may have missed, and highlighting relevant management options — all before the encounter concludes.

Complex cases get no extra analytical support. Glass Health includes a Deep Reasoning mode that dedicates extended computational analysis to complex, multi-system clinical presentations. Heidi has no comparable feature for deepening clinical reasoning on difficult cases.

EHR access requires a premium plan. Heidi offers EHR integrations with multiple systems including Epic, Athenahealth, and eClinicalWorks, but these are locked behind the Practice ($99/user/month) and Enterprise tiers — the Free and Pro plans do not include them. KLAS Research flagged EHR integration as an area needing improvement. Glass Health’s EHR integration with Epic, eClinicalWorks, and Athena is available on the Max plan.

Pricing Comparison

	Glass Health	Heidi Health
Free tier	Lite — $0/month (limited CDS + limited ambient scribing)	Free — $0/month (unlimited notes, 10 Pro Actions/month)
Starter	$20/month ($18/month annual) — extended CDS + ambient scribing	—
Pro	$90/month ($81/month annual) — unlimited scribing, CDS, all documentation types	Pro — $99/month ($66.60/month annual) — unlimited Pro Actions, custom templates
Max	$200/month ($180/month annual) — everything + EHR integration (Epic, eCW, Athena)	—
Team	—	Practice — $99/user/month ($1,199/user/year annual) — shared templates, EHR, MFA
Enterprise	Custom pricing available	Enterprise — custom (SSO, coding, org-wide BAA)
Contract	Month-to-month or annual	Month-to-month or annual

Both platforms offer free tiers, but they include different capabilities. Heidi’s free tier provides unlimited basic note generation — strong for pure documentation. Glass Health’s free Lite tier includes both limited scribing and limited CDS — differential diagnosis, assessment and plan, and clinical Q&A.

At the paid level, Glass Health Pro ($90/month) delivers unlimited scribing plus the full CDS suite (three-tier DDx, A&P, clinical Q&A, Deep Reasoning, 6 doc types, custom templates) for less than Heidi Pro ($99/month), which provides unlimited documentation without any clinical decision support.

Both tools reduce charting time through ambient scribing. Heidi’s strength is fast, accurate note generation across 200+ specialties with extensive template support. Glass Health reduces charting time while also providing clinical decision support that eliminates context-switching to separate reference tools. Research indicates documentation and charting are cited by 16% of providers as their primary driver of burnout (Tebra, 2024), and CDS integrated into workflows improves diagnostic processes (Nature, 2020).

Is Heidi Health available in the United States?

Yes. Heidi Health operates in the U.S., Canada, Australia, New Zealand, and the United Kingdom, with expansion into Ireland, France, Spain, South Africa, and other markets. The company was founded in Australia and has established a growing U.S. presence with HIPAA compliance and regional data sovereignty.

Bottom Line

Glass Health vs Heidi Health comes down to whether you need just documentation or documentation plus clinical reasoning. Heidi Health is a widely used pure AI scribe — 110+ languages, a generous free tier, and broad global reach. But Heidi is only a scribe. It does not generate differential diagnoses, assessment and plans, clinical Q&A answers, or real-time diagnostic insights.

If documentation is your only bottleneck, Heidi is among the best options available. But if you also need diagnostic support during encounters — structured DDx, evidence-based A&P generation, clinical Q&A with citations to clinical guidelines and medical literature, and patient context that carries forward across visits — Glass Health bundles all of that with ambient scribing at $90/month, less than Heidi Pro’s $99/month.
