Serverless Lead Gen Chatbot
A serverless lead gen web application that combines AI interactivity with automated email responses.
Overview
This system captures user form input, processes it through the openAI API to generate entertaining, intelligent responses. The form information and AI response are then automatically emailed to the website owner using SendGrid.
Why I Built It
A friend needed a low-friction way to turn website conversations into actionable leads without building a complex support infrastructure. The challenge was creating something that felt conversational and helpful to users while being simple to implement and maintain.
What I Built
- Form Input Capture: Web form that collects user information and questions
- AI API Integration: Processes user input through an AI service to generate contextual responses
- Email Automation: Uses SendGrid to automatically email the website owner with lead details
- Lightweight UI: Minimal, embeddable interface that works on any website (currently embedded in webflow)
- Configurable System: Customizable AI prompts and email templates
Tech Behind the Scenes
Frontend
HTML5/CSS3 with JavaScript for form handling and responsive design. The UI is designed to be lightweight and embeddable on any website.
Backend
Serverless functions handle the complete workflow: form processing, AI API calls, and email automation. The architecture is designed for scalability and cost-effectiveness.
Integration
- AI API for generating intelligent responses
- SendGrid for reliable email delivery
- Environment-based configuration for easy deployment
What I Learned
- API Integration: Working with external APIs requires robust error handling and fallback strategies, especially if you don’t want to be doing a lot of support!
- Serverless Architecture: Perfect for this use case, scales automatically and keeps costs low
- User Experience: The key is making the AI responses feel helpful, not robotic, and putting guardrails to ensure they are not offensive.
Takeaway
This project demonstrates how modern serverless architecture can create powerful business tools with minimal complexity (I created this in one week of development time). The combination of AI integration and email automation creates a complete lead generation system that’s both user-friendly and business-focused.
