AI scribe vs session evidence

For therapists, psychiatrists, and the platforms that serve them: audio-only tools document what was said. Session evidence records how the body responded — then delivers that as reviewable FHIR R4 evidence.

SeroState is not an AI scribe. It is the physiological layer those tools do not produce.

The limit of audio-only tools

Words can mask distress. Physiology doesn’t.

Behavioral-health sessions are full of moments where the verbal record and the autonomic record disagree. A patient says “I’m fine” while heart rate spikes. An AI scribe — or any transcript-first note tool — correctly captures the sentence. The physiological event never enters the chart.

That is not a failure of note quality. It is a missing measurement layer. Why documentation misses the encounter →

Illustrative. The scribe has the sentence. Session evidence has the spike, the window, and a confidence score for the clinician to accept or dismiss.

FAQ

Frequently asked questions

Is SeroState an AI scribe for therapists?

No. SeroState is session evidence: wearable and vocal physiology time-aligned to the conversation and delivered as FHIR R4 evidence. It does not author the clinical note. The clinician always decides.

How is it different from an AI therapy note tool?

Note tools summarize what was said. Session evidence records how the nervous system responded — heart rate first, vocal markers when available, HRV and EDA when the session wearable provides them — then flags say/body gap moments for review.

Can it work alongside an AI scribe?

Yes. Many platforms already generate notes from audio. SeroState adds a physiological evidence layer on the same session timeline, delivered by API into the EHR or telehealth stack.

Who buys this?

EHR and telehealth platforms, health systems, research groups, and trial sponsors. Clinicians access it through their existing platform — not as a separate app they install.
