PsyOS is an AI-orchestrated behavioral health EHR platform that reimagines treatment delivery through avatar-based care planning and multi-agent AI coordination. The system maintains a living digital representation of each patient (Mirror Avatar) and their recovery goals (Aspirational Avatar), with treatment conceptualized as measurable gap closure between these states. Powered by Claude via Amazon Bedrock, specialized AI agents manage clinical documentation, risk assessment, treatment planning, medication optimization, billing, and compliance enforcement. The platform supports multi-modal documentation including voice dictation and ambient listening, real-time clinical decision support, and automated regulatory compliance across federal, state, and payer requirements.
