OncoMate (live demo at onco.services) is a production-style reference implementation for building AI copilots in regulated environments:

• Stack: Next.js App Router, Supabase (Auth + Postgres + Edge Functions), LangChain, OpenAI GPT-4, Tailwind UI.
• Workflow: Field engineers upload telemetry + maintenance notes. A retrieval pipeline selects the right device manuals and past tickets, then an agent builds a fix plan.
• Guardrails: Role-based access, audit logging, deterministic fallback answers when grounding fails.
• Outcome: Reduced troubleshooting time from hours to minutes during pilot tests, while keeping sensitive data inside a single Supabase project.

Upcoming posts will cover the architecture diagram, RAG evaluation harness, and deployment tips for healthcare teams.
