BastionGPT vs Ambience Healthcare: AI Medical Scribe Comparison for 2026

You can buy it today

Ambience sells exclusively to health systems through an enterprise sales process. Independent reviews confirm there is no self-serve signup, no free trial, and no small-practice tier, and position the platform as best suited to organizations with 50 or more providers (DeepCura, March 2026). Deployment is an IT project: Ambience's own informatics page lists an average implementation time of 4 weeks with white-glove onboarding, independent guides describe 2 to 6 weeks of EHR configuration and security sign-off (OmniMD, July 2026), and full health-system rollouts can stretch to months depending on system size.

BastionGPT deploys in minutes. Sign up, start the 7-day free trial, and record your first session the same day, with a signed BAA in place from the moment you begin. There is no procurement cycle, no committee, and no IT dependency. For a clinician whose health system has not rolled out an ambient tool, or has rolled one out that they cannot use the way they want, that difference is the whole decision.

Published pricing you can verify

Ambience does not publish pricing anywhere on its website. Third-party analysis estimates base AutoScribe contracts at roughly $2,800 to $3,200 per provider per year ($233 to $267 per month), with the full suite reaching $4,000 to $5,000 per provider per year ($333 to $417 per month), plus a one-time implementation fee covering EHR integration and template configuration (DeepCura, March 2026). Other industry guides place entry pricing near $200 per provider per month before enterprise add-ons (AssemblyAI, June 2026). Because every contract is custom, the only way to learn your actual price is to enter the sales process.

BastionGPT publishes its prices: Professional at $20 per user per month, Professional Plus at $45, and Ultra at $75, with annual billing that includes a free month. Prices have held steady for over two years.

The math for a five-clinician practice: at the third-party full-suite estimate, Ambience would run $20,000 to $25,000 per year before implementation fees. BastionGPT Professional Plus runs $2,700 per year ($45 x 5 x 12). That is a difference of roughly $17,000 to $22,000 per year, and in practice a five-clinician group typically cannot purchase Ambience at all.

A full AI assistant, not only a scribe

Every Ambience module anchors to the EHR encounter: AutoScribe documents the visit, AutoCDI validates the coding, AutoAVS writes the after-visit summary, AutoRefer drafts the referral, and chart-aware tools prepare the clinician beforehand. That is a deep pipeline for one workflow. It does not include a general-purpose assistant, and Ambience publishes no support for uploading your own documents, spreadsheets, or images for analysis.

BastionGPT includes an unlimited general AI assistant on every plan. Clinicians use it to draft referral letters, insurance appeal letters, treatment plans, and patient education materials; review documentation for incorrect names, pronouns, vague language, and suspected under- or over-coding; and analyze lab summaries and spreadsheets. BastionGPT cites 99.3% sentence-level accuracy on clinical documentation tasks from a peer-reviewed study by Baylor College of Medicine and Texas Children's Hospital researchers.

‍

Read a whole record, not just the chart in front of you

On Professional Plus and Ultra plans, BastionGPT reads 10+ documents at once, up to 1,000+ pages of combined context. Supported formats include PDF, Word, Excel, CSV, PowerPoint, HTML, plain text, and JPG or PNG images, including scanned PDFs, charts, and graphs. A clinician can upload a psychological evaluation, outside records from multiple providers, and an insurance denial letter, then query, summarize, and cross-reference all of it in one conversation.

Ambience reads the patient's longitudinal chart through its EHR integration, which is valuable inside a deployed health system. It publishes no capability for records that live outside that EHR: faxed outside records, legal documents, spreadsheets, or anything a clinician receives directly.

‍

AI models you can see and choose

BastionGPT names its engines: licensed and HIPAA-compliant versions of GPT-5.5, Claude, and Gemini 3 Pro. Every plan selects the best model for each task automatically, and Professional Plus adds manual model selection plus early access to new models as they ship. Model quality drives note quality, and naming the models lets you verify exactly what is reading your records.

Ambience builds on OpenAI models delivered through Microsoft Azure, per its Microsoft Marketplace listing and its own product announcements. That is a single-vendor model stack, and clinicians cannot see or select which model handles a given task.

‍

A stricter boundary around patient data

BastionGPT enters a signed Business Associate Agreement with every customer on every plan, including the free trial. Prompts, documents, and audio are never shared with OpenAI or any other AI provider for training, chats and transcripts are wiped after 30 days by default, and data is encrypted with AES-256 at rest and TLS in transit on HITRUST CSF certified and SOC 2 Type II attested Microsoft Azure infrastructure, with independent penetration testing at least annually. Organizations with stricter requirements can host regionally in the United States, Canada, or Australia, and the Ultra plan can deploy within your organization's own enterprise cloud. In three years serving more than 10,000 healthcare organizations, BastionGPT has had zero breaches of protected health information.

Ambience operates as a HIPAA Business Associate and maintains SOC 2 Type I and Type II certification. Its privacy policy also states that it discloses de-identified patient information to third-party service providers and academic researchers where its customer contracts and HIPAA permit, using the safe harbor or expert determination methods. That is legal under HIPAA, and it is also a clause worth reading closely during procurement if your organization has told patients their data stays inside the care relationship.

‍

Compliance coverage beyond HIPAA

BastionGPT supports HIPAA, 42 CFR Part 2, FERPA, PIPEDA, PHIPA, and Australian APP requirements, with DocuSign BAAs available on request. Substance-use treatment programs and school-based providers get named regulatory coverage on every plan.

Ambience publishes HIPAA and GDPR adherence alongside its SOC 2 certifications. It does not publish 42 CFR Part 2 or FERPA support.

‍

Human support on every plan

BastionGPT provides support by email, chat, phone, and video with real humans on every plan, backed by a 99.90% uptime guarantee. Ambience provides enterprise implementation and support teams to its health system customers, with SLA terms set per contract. If you are one clinician inside a large deployment, your support path runs through your organization's IT department.
