DrTalks
AI Chat Widget
Transforming Healthcare Conversations
The Client
DrTalks is a healthcare technology company helping doctors build stronger connections with patients online. They needed a solution that would let medical practices embed AI-powered chat on their websites: something that could answer patient questions accurately, qualify leads, and drive appointment bookings, all while maintaining the doctor's unique voice and expertise.
Making medical knowledge accessible, one conversation at a time
DrTalks needed a way to help doctors connect with patients online - not through generic chatbots, but with intelligent conversations backed by real medical expertise. We built them an AI-powered chat widget that healthcare providers can embed on their websites, giving patients instant access to accurate information while capturing valuable leads for medical practices.
Key Features
AI-Powered Chat Widget
Embeddable React widget that answers patient questions using the provider's own knowledge base. Conversations feel natural and helpful, not robotic.
Multi-Tenant Dashboard
Complete organization management system where healthcare providers control their widget, upload content, and track performance. Authentication handled through Clerk.
Knowledge Base Management
Doctors upload treatment guides, FAQs, and medical content. The system processes everything into searchable information using vector embeddings.
Real-Time Analytics
Track conversation volumes, response times, and the questions patients ask most. Understand what your audience cares about with P95/P99 performance metrics.
Easy Embed
Simple script tag integration - just add a few lines to any website. The widget handles the rest with automatic origin validation and security.
Live Widget Preview
Test configurations in real-time before deployment. See exactly how patients will experience your AI assistant.
Session Management
UUID-based ephemeral sessions keep conversations private and secure without requiring patient login.
Self-Service Signup
Automated Stripe onboarding lets providers get started in minutes. Complete organization setup happens automatically.
Usage Tracking
Monitor chat volume, analyze top questions, and understand how patients interact with your widget.
Rate Limiting
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.
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.
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.
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.
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.
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.
Our Team Behind the Project
Building an AI-powered healthcare platform required specialists who understood both the technology and the domain.
Built the widget and dashboard from the ground up, ensuring seamless integration between patient-facing chat and provider controls.
Implemented the RAG system, optimized embedding workflows, and fine-tuned response quality for medical conversations.
Created intuitive interfaces for both patients and providers, focusing on accessibility and ease of use.
Ensured everything worked flawlessly across devices, browsers, and edge cases. Healthcare tools can't afford bugs.
Set up secure, scalable infrastructure on Vercel with proper monitoring, backups, and deployment pipelines.
Considerable Achievements
The platform delivered results immediately after launch, proving strong product-market fit.
Rapid Market Validation
Healthcare providers saw the value instantly - accurate AI conversations that don't require technical setup or ongoing maintenance.
Improved Patient Experience
Patients appreciated getting instant, trustworthy answers instead of searching through pages or waiting for office hours.
Direct Revenue Impact
By qualifying leads and encouraging bookings during conversations, the widget directly increased patient acquisition for medical practices.
Making Healthcare Accessible Through Conversation
Our collaboration with DrTalks resulted in a platform that genuinely helps both sides of healthcare. Patients get accurate information when they need it. Doctors capture leads they would otherwise lose while maintaining complete control over what information gets shared.
The widget works seamlessly across different medical specialties - from family medicine to specialized practices. It scales effortlessly as providers grow their knowledge bases, and the self-service model means new customers can go live in minutes.
This wasn't about building another chatbot. It was about solving a real problem: the gap between curious patients and busy healthcare providers. By combining modern AI with thoughtful design and healthcare-specific requirements, we delivered something that creates value every single day.
