What Aggi ARIA actually does for you

Your AI passed its compliance review in March. It's June. Is it still the same AI?

A patient sees her doctor on Monday. On Wednesday she calls back about her new medication, with a question about a side effect or the dose.

In a good experience, your AI assistant already knows who she is. It picks up where the visit left off, and she does not have to re-explain her history, her medication or her allergy list.

Pause on what just happened underneath that smooth moment. Her clinical history, her active prescriptions and her identity, all of it protected health information (PHI), were carried forward, held in context, and very likely passed between systems and between AI models to make the conversation feel effortless.

Every one of those handoffs is a decision a regulator cares about:

• Was only the minimum necessary PHI carried forward, or the whole chart?
• Did the patient's context cross into a model covered by a different BAA (business associate agreement, the HIPAA contract with each vendor that handles PHI), with different retention rules?
• When the AI recalled her medication, did it recall it accurately, or confidently invent a detail?
• Did she get information that quietly drifted toward clinical advice your policy says it should not give?

You may have validated all of this at launch. AI drifts anyway, in at least four ways:

• The model changes. Your vendor ships an update, and the system that passed review is not the one running today.
• The prompts evolve. A tweak to improve the experience quietly weakens a PHI safeguard.
• The inputs shift. Real patients do not talk like your test cases.
• The rules move. A new framework, a new health-system requirement or a new state AI law takes effect, and nothing has been re-checked against it. Texas's TRAIGA (the Texas Responsible Artificial Intelligence Governance Act) has been in force since January 2026, and other states are following.

A point-in-time compliance report is a photograph. Your AI is a video.

That is the gap Aggi ARIA (Aggi Responsible Intelligence Assessor) closes. We continuously test whether your AI actually follows your policy on minimum-necessary PHI, refusal behavior, hallucination and BAA boundaries, and hand you the evidence on the day a health system's security team asks. You get behavioral proof, refreshed continuously.

Responsible AI, Verified.

If you are building patient-facing AI: when procurement asks you to prove your model still behaves the way it did at launch, what do you show them?
