Healthcare Platform Demo

A real-time healthcare communication platform combining PubNub messaging, presence, critical alerts, care-team coordination, and an AI chatbot to deliver instant, secure patient-provider interactions

About this demo

This healthcare demo shows how you can use PubNub's JavaScript SDK to build a real-time healthcare platform with instant messaging, presence indicators, critical alerts, care-team coordination, and an AI-powered chatbot.

PubNub handles all real-time data — messages, presence, alerts, file sharing, task events, and notifications — through dedicated channels with no custom WebSocket server required. PubNub Functions run server-side logic for keyword-based alert detection, task creation via slash commands, and AI bot responses — all at the edge with sub-millisecond latency.
