Inspiration Most of a patient's life happens between appointments, and most clinics only see it as a shrug at the next visit. A two-minute talk on a wrist band can capture how someone actually is. Once that note exists, the awkward back office around it (safety review, copay, billing) should not need a human typing.
What it does The wearer double-taps a Vexo band and has a short spoken check-in about sleep, mood, stress and appetite. The result is a structured, non-diagnostic note in the wearer's own words. NeuroKind then adds three things on top:
- Gemini Decision 1 safety gate. Crisis language or low confidence holds the session for a human. Any gate error fails closed.
- Deterministic copay. Computed from a synthetic eligibility file, never by a model.
- Stripe test-mode invoice. The copay invoice is staged with a payment link. Payment needs a band double-tap and the spoken word "confirm" within 60 seconds. Voice alone never pays, and a hard cap of $50 and a once-only rule apply.
A Flow Monitor then runs seven deterministic checks, plus an optional OpenAI audit of the note against the transcript.
How we built it
The voice check-in is a Pipecat pipeline: Vexo band mic over Bluetooth, Deepgram speech to text with redaction, Gemini 4 for the conversation, ElevenLabs for the voice. The NeuroKind layer (gate, billing, Stripe, monitor) is in neurokind_post.py and core/ in the repo.
Sponsor roles
- Vexo: the band, with mic, taps and tilt.
- Google DeepMind: Gemini 4 writes the note and Decision 1 is the safety gate.
- Stripe: test-mode copay invoice and payment link.
- Deepgram: speech to text on the band mic, on Pipecat.
- ElevenLabs: the agent's voice.
- OpenAI: an independent audit of the note.
Honest status 16 unit tests pass with the network calls faked (flow, billing guards, gate routing, monitor, and the full pay path). The live Gemini Decisions call, the live Stripe invoice and payment, the live OpenAI audit and the full band path end to end have not been run together yet. Synthetic data only. Stripe test keys only.
