Most contact forms are just inboxes. This one has a brain.

In this video, I build a complete AI-powered Smart Contact Form using n8n + OpenAI + Supabase that:
* Auto-categorizes user messages
* Detects priority (high, medium, low)
* Stores data in Supabase automatically
* Alerts admins instantly for high-priority messages

All from scratch — frontend, n8n workflow, OpenAI prompt engineering, database setup, and conditional Gmail alerts. Zero manual work.

What You’ll Build?
Pipeline:
Frontend Form → n8n Webhook → OpenAI → Supabase DB → Gmail Alert → Admin

What You’ll Learn?
* Setup a frontend contact form and connect it to n8n via Webhook
* Write OpenAI prompts to extract category (sales, support, spam, job) & priority (high / medium / low)
* Create and map a Supabase PostgreSQL table
* Auto-insert form data into the database
* Use conditional logic to trigger Gmail alerts for high-priority messages
* Handle timestamps correctly for DB storage

Real-World Use Cases:
* SaaS companies auto-routing client requests to the right team
* HR teams auto-prioritizing job applications
* Support desks never missing urgent leads

Why This Matters in 2026?
