AI Chat Agent

Key Features

• Embeddable AI chat widget

  Answers patient questions using the provider's own knowledge base. Conversations feel natural and helpful, not robotic.

• Organization dashboard

  A complete management system where providers control their widget, upload content, and track performance. Authentication handled through Clerk.

• Knowledge base ingestion

  Doctors upload treatment guides, FAQs, and medical content. The system processes everything into searchable information using vector embeddings.

• Conversation analytics

  Track conversation volumes, response times, and the questions patients ask most — with P95/P99 performance metrics.

• One-line embed

  Simple script-tag integration — add a few lines to any website. The widget handles the rest with automatic origin validation and security.

• Live preview

  Test configurations in real time before deployment. See exactly how patients will experience your AI assistant.

• Private sessions

  UUID-based ephemeral sessions keep conversations private and secure without requiring patient login.

• Instant onboarding

  Automated Stripe onboarding lets providers get started in minutes. Complete organization setup happens automatically.

• Usage insights

  Monitor chat volume, analyze top questions, and understand how patients interact with your widget.

• Rate limiting & abuse protection

  Per-site quotas and intelligent throttling prevent abuse while ensuring smooth performance for legitimate users.

The Technology Behind It

We built this platform to handle the unique demands of healthcare — accuracy, security, and reliability at scale.

• Custom AI Engine

  The heart of the system is RAG (Retrieval-Augmented Generation). When a patient asks a question, the AI doesn't just generate an answer — it searches through the doctor's approved knowledge base first. This means responses are grounded in real medical content, not generic internet information. We combined OpenAI's GPT models for conversation with ada-002 embeddings for understanding context and finding relevant information.

• Fast, Lightweight Widget

  The embeddable chat runs on React 18 with TypeScript, bundled efficiently with Webpack 5. It loads in milliseconds and uses SCSS for responsive, mobile-first styling that works beautifully on any device.

• VidRTC-Inspired Architecture

  While we didn't need video streaming, we applied the same scalability principles that power our VidRTC conferencing engine. The widget is built to handle high traffic without slowing down provider websites.

• Powerful Dashboard

  Healthcare providers get a modern Next.js 15 interface with Tailwind CSS and Radix UI components. Everything from uploading documents to monitoring performance happens in one place.

• Security & Compliance

  Healthcare data requires serious protection. We implemented origin validation to prevent unauthorized embedding, XSS prevention to block malicious scripts, and comprehensive rate limiting. Session data is ephemeral — conversations happen in secure, temporary spaces that don’t persist sensitive information.

• Database Architecture

  PostgreSQL with pgvector extensions enables lightning-fast semantic search through thousands of medical documents. As knowledge bases grow, performance stays consistent. Everything runs on Supabase for reliable backend infrastructure.

• Intelligent Automation

  n8n workflows handle document processing automatically — extracting text, creating embeddings, and updating the knowledge base without manual intervention.

Considerable Achievements

The platform delivered results immediately after launch, proving strong product-market fit.

• Rapid Market Validation

  30

  clients signed up in the first week.

  Healthcare providers saw the value instantly — accurate AI conversations that don't require technical setup or ongoing maintenance.

• Improved Patient Experience

  80%

  increase in customer satisfaction.

  Patients appreciated getting instant, trustworthy answers instead of searching through pages or waiting for office hours.

• Direct Revenue Impact

  40%

  more appointments booked.

  By qualifying leads and encouraging bookings during conversations, the widget directly increased patient acquisition for medical practices.
