System Architecture

Care Collaborative runs three distinct use cases on one platform — a single-binary Runtime with embedded Temporal orchestration, real-time WebRTC media, an AI Governance proxy, and Cloudflare edge delivery. Each use case has its own dedicated architecture site below.

Clinical

Patient Simulation Training

Real-time voice · STT → LLM → TTS

An AI patient agent joins a live WebRTC room and role-plays a clinical scenario. Students conduct the encounter by voice while the platform transcribes, generates the patient's responses, and speaks them back in real time.

Scenario-driven AI patient personas

Provider-agnostic STT / LLM / TTS pipeline

Template-driven communication assessment

Workplace

Workplace Conduct Training

Real-time voice · STT → LLM → TTS

An AI persona joins a live WebRTC room and role-plays a workplace scenario — conduct review, performance feedback, conflict resolution. The trainee handles the conversation by voice in real time.

Feedback

Feedback Evaluation

Async analysis · Transcript → LLM → PDF

A human evaluator and participant hold a live feedback session that is recorded and transcribed. No AI agent joins the room — analysis happens asynchronously after the session ends.

Human-to-human session — no agent pipeline

Dual parallel analysis (participant + evaluator)

Evidence-quote mapping with confidence scores
