If you work in healthcare and you've started looking into HIPAA-compliant AI, two names keep coming up: Hathr.AI and BastionGPT. Both promise secure, compliant generative AI built for sensitive data. Both offer a BAA. Both position themselves as safer alternatives to raw ChatGPT or Claude. But they are not the same product, and the right choice depends on what you actually need day to day.
Common groundWhere they overlap
Both Hathr.AI and BastionGPT check the core compliance boxes:
- HIPAA compliance with a signed BAA on every plan
- Data encryption at rest and in transit
- A commitment to never use customer data for model training
- Document upload, clinical note generation (SOAP, DAP, and similar formats), and general-purpose AI chat for healthcare professionals
Both also serve adjacent verticals like legal and insurance, though to different degrees.
Clinical workflowBastionGPT pulls ahead on day-to-day clinical work
This is where the gap becomes clear. BastionGPT was built from the ground up as a clinical AI assistant, and it shows. The platform includes a dedicated AI Scribe with unlimited transcription on every plan, multi-speaker recognition, and six structured output formats. You record a session, and BastionGPT drafts the note: SOAP, DAP, BIRP, narrative, or a fully custom template you define yourself.
Hathr.AI can generate clinical notes from uploaded or dictated text, but it doesn't offer a comparable built-in scribe experience. It's closer to a secure chat interface with document processing bolted on. For a solo therapist or a psychiatrist who needs to turn a 50-minute session into a polished progress note in under two minutes, BastionGPT's scribe is the more complete tool by a wide margin.
BastionGPT also provides purpose-built prompts for referral letters, discharge summaries, appeal letters, and patient education materials. These aren't generic templates; they're tuned for clinical language and formatted the way an EHR expects to receive them. Hathr.AI can produce similar output with the right prompting, but the user has to do more of the structural work themselves.
BastionGPT offers more model firepower
BastionGPT runs a multi-model backend that includes GPT-5, o3, Claude Opus, and Gemini 3 Pro. Different response modes route prompts to the model best suited for the task, whether it's a complex differential diagnosis question or a simple note rewrite. This matters because no single model excels at everything, and access to the full roster means more consistent results across diverse clinical tasks.
Hathr.AI is powered by Anthropic's Claude models hosted on AWS GovCloud. Claude is excellent, and for pure document summarization it performs on par as of this writing — but a single-model architecture means you're dependent on one provider's strengths and weaknesses. Model leadership shifts on a weekly basis as the major labs ship new versions. For tasks that benefit from broader model diversity (coding suggestions, complex reasoning, creative clinical language), BastionGPT's multi-model approach delivers more consistent quality.
PricingPricing and accessibility
Both platforms start at comparable price points, but the floor is different.
For individual practitioners and small practices watching their overhead, BastionGPT's lower starting price plus the included unlimited scribe make it the stronger value. You get a clinical AI assistant and a full transcription tool for less than what a chat-only subscription costs on the other side.
Federal & DoDHathr.AI's strength: government and defense
This is where Hathr.AI stands out. Hathr.AI is hosted on AWS GovCloud in a FedRAMP High environment. It conforms to standards that allow it to handle Controlled Unclassified Information (CUI) at Impact Levels 2, 4, and 5. It has been approved to join the Military-Civilian Health Ecosystem administered by the National Institute for Defense Health Cooperation.
If you work for a federal agency, a DoD contractor, or the VA, Hathr.AI is purpose-built for that environment. BastionGPT runs on Microsoft Azure's HIPAA-compliant infrastructure, which is secure and well-suited for private healthcare organizations, but it does not target FedRAMP High authorization or defense-sector compliance.
Document handling
Both platforms support large document uploads. BastionGPT's Professional Plus plan and Hathr.AI's plan both handle documents exceeding 500,000 words. BastionGPT additionally advertises this capability with multi-document referencing and OCR for scanned files.
For the vast majority of clinical use cases, 500,000 words covers even lengthy multi-hundred-page psych evaluations and full medical histories. The ceiling matters more in government contexts where you're processing massive contract packages or policy libraries — another place where the federal use case nudges toward Hathr.AI.
The verdictPick the tool that matches your environment
BastionGPT is the more complete clinical platform
For healthcare professionals in private practice, clinics, therapy groups, hospitals, and health systems, BastionGPT is the more complete tool. Its multi-model AI engine, built-in unlimited scribe, structured clinical templates, and lower starting price make it the gold standard for clinical AI documentation. It does what clinicians actually need, and it does it well.
Hathr.AI could be the right call
If your procurement team requires FedRAMP High or Impact Level 5 authorization, Hathr.AI meets those requirements in a way that most commercial healthcare AI tools do not. For federal or DoD organizations that need compliance with those specific frameworks, it's the appropriate platform.
Pick the tool that matches your compliance environment and your daily workflow. For most healthcare professionals, that's BastionGPT. For federal and defense health teams, that's Hathr.AI.
