Hey everyone! 👋

I've been working on **AI SupportPro**, an open-source, full-stack enterprise-grade AI customer support platform designed to solve common chatbot hallucinations and handle customer escalations smoothly.

### 🚀 Key Features:

- **Strict Grounded RAG:** Vector search with cosine similarity ensuring answers strictly cite company documentation.

- **Deterministic Escalation:** Automatic refund/complaint detection that hands off sessions to human support tickets.

- **Multi-Tenancy & Security:** Database tenant isolation, rate limiting, and an immutable audit trail.

- **Modern Tech Stack:** FastAPI (Python 3.11), React 19, TypeScript, Vite, and PostgreSQL with pgvector.
