A study out of Baylor College of Medicine and Texas Children's Hospital tested an AI tool inside a pediatric intensive care unit's actual communication workflow. Across 1,225 AI-generated sentences, three independent physician reviewers found 99.3 percent sentence-level accuracy.
The tool behind that number is BastionGPT. Here's what it actually is, how it works, and whether it's worth your clinic's attention.
What BastionGPT Actually Is
BastionGPT is a HIPAA-compliant AI assistant and AI medical scribe built for healthcare professionals. Developed by Bastion Intelligence, a Microsoft Partner, the platform integrates GPT-5.2, Claude Opus, and Gemini-3 Pro in a secure, clinical-grade interface.
Under the hood, BastionGPT routes across 200+ models including GPT, Claude, and Gemini, so you're using the same frontier models as the consumer apps, accessed through a secure healthcare-specific architecture.
That's the core pitch in one sentence. The same AI power you'd get from ChatGPT, wrapped in the compliance infrastructure a hospital or clinic actually needs.
Why This Isn't Just ChatGPT With a Different Logo
Here's the thing that separates a genuinely useful clinical tool from a rebranded consumer chatbot. A BAA, business associate agreement, is included on every plan. Patient data is never shared with third parties for training.
That distinction matters enormously in practice. A doctor pasting patient notes into standard ChatGPT is creating a real HIPAA violation risk, since OpenAI's consumer terms don't offer the legal protections healthcare data requires. Bastion built its entire product around closing that exact gap.
One clinician reviewer put it simply: Bastion is like Chat GPT but knows what healthcare practitioners need, including the privacy systems that are crucial to our work.
The Features That Actually Save Time
Let me walk through what the platform does day to day.
Clinical Documentation
The platform drafts progress notes including SOAP, DAP, and BIRP formats, referral letters, discharge summaries, insurance appeals, patient education materials, and evaluation reports. For any clinician who's spent an evening catching up on notes instead of going home, this is the feature that changes that math.
AI Scribe and Transcription
BastionGPT allows for unlimited audio transcriptions for sessions up to 4 hours with 10 different speakers in 20+ different languages. The AI Scribe recognizes multiple speakers in a room automatically and outputs into six configurable formats depending on what documentation style your specialty requires.
Document Analysis
Users upload and analyze documents up to 1,000 pages on the top tier, with OCR support for scanned files. That's genuinely useful for reviewing lengthy medical histories or research documents without manually reading through every page.
Saved Prompts and Team Standardization
A built-in Saved Prompts Library and Share Prompts feature help teams standardize workflows across their organization. If your clinic has a specific note format everyone should follow, this locks that consistency in across the whole team rather than relying on individual habits.
The Memory Question Worth Understanding Before You Sign Up
Here's a design decision that trips people up if they're expecting BastionGPT to behave like a typical AI chat tool.
A May 2026 paying customer reported BastionGPT does not retain learned vocabulary or context between sessions. This is intentional: persistent memory across encounters would create a path for one patient's information to leak into another, which is incompatible with HIPAA.
The intended workaround is a saved prompt that includes your reference materials and context, re-applied each session. It's a deliberate trade-off, less convenience, more compliance, and it's worth understanding going in rather than being surprised by it on day three.
Pricing Breakdown
Here's what each tier actually costs and includes.
Plan | Price | What You Get |
|---|---|---|
Professional | $20/month per user | HIPAA-secure AI, AI Scribe, unlimited audio transcription, documents up to 30 pages |
Professional Plus | $45/month per user | Larger documents up to 500 pages, multiple file uploads |
Ultra | $65/month per user | Documents up to 1,000 pages, customized pricing available |
A free trial is available, and the BAA is included on the trial too, so you can genuinely test the platform on real workflows before committing rather than evaluating it in a sandboxed demo environment.
Reviews: What Real Clinicians Are Saying
The platform holds a 4.8 out of 5 average across Capterra and Software Advice, drawn from real clinician feedback.
The recurring praise centers on ease of use. It's easy to use, very little time is spent working it out as it has such a straightforward, clean interface. I love the system of prompts and have refined mine to get what I need. I tried many AI programs and Bastion hits the mark. I kept going back to it and finally just stayed.
Honest criticism is genuinely thin. The most common complaint on record: I can't think of many cons. If pressed, being able to select British spellings would be great, but you can ask Bastion to add use them in your prompt. That's about as minor as negative feedback gets for any software product.
How It Fits Alongside General AI Chatbots
If you've already been evaluating general-purpose AI tools for your own workflows, whether personal or professional, it's worth understanding where BastionGPT sits relative to platforms like ChatGPT and Claude directly. We broke down how those mainstream tools compare on writing quality, research capability, and pricing in our best AI chatbots guide, and BastionGPT is essentially what happens when those same underlying models get purpose-built compliance infrastructure wrapped around them for a regulated industry.
That's not a knock on either category. General AI chatbots are excellent for most knowledge work. Healthcare specifically needs the HIPAA layer, and that's the entire reason a tool like this exists instead of clinicians just using ChatGPT directly.
Who Should Actually Use This
Physicians, therapists, nurse practitioners, and clinical documentation specialists get the most direct value, particularly anyone spending real hours weekly on notes, referral letters, or patient communication drafts.
Multi-provider practices benefit from the Saved Prompts Library specifically, since standardizing documentation style across a team of clinicians is a genuine administrative headache this feature solves cleanly.
Solo practitioners on a tight budget should start with the Professional tier's free trial and see whether the 30-page document limit actually constrains their real workflow before upgrading.
The Study Results in Full Context
The Baylor and Texas Children's Hospital research deserves a closer look since it's the strongest independent validation this product has.
The feasibility study, published in Critical Care Explorations in April 2026, used BastionGPT as the chatbot platform in a pediatric ICU communication workflow. Beyond the headline 99.3 percent accuracy figure, the study reported a Gwet's AC2 inter-rater agreement of 0.98 among the three physician reviewers, meaning the doctors evaluating the AI's output largely agreed with each other about its quality, not just that the AI performed well by one reviewer's individual judgment.
That's a meaningfully rigorous result for a clinical AI tool, and it's rare to see this level of peer-reviewed validation this early in a healthcare AI product's life.
Is BastionGPT Worth It
For any healthcare practice currently avoiding AI tools entirely out of HIPAA concern, or worse, using consumer ChatGPT and hoping nobody notices, BastionGPT closes that gap directly. The pricing sits in a reasonable range for the documentation time it saves, and the compliance infrastructure is exactly what a hospital's legal and IT teams would actually require before approving any AI tool for clinical use.
The free trial with BAA included makes this a genuinely low-risk evaluation. Test it against your actual documentation workload for two weeks and the time savings should be obvious immediately.
FAQs
What is BastionGPT used for?
A HIPAA-compliant AI assistant for healthcare professionals that drafts clinical notes, transcribes patient sessions, and analyzes medical documents securely.
