GenAI · SaaS

Overview

A SaaS platform where many companies run isolated AI-powered WhatsApp support and sales bots from a single deployment (Live Demo: https://multi-tenant-whatsapp-agent.vercel.app) — each with its own persona, catalog, and knowledge base.

  • LangGraph agent with a 4-node pipeline (acknowledge → retrieve context → LLM reasoning → dispatch) and per-tenant RAG indices.

  • Multimodal: PDF catalog ingestion with image extraction, inbound image vision analysis, and document sending.

  • Admin dashboard for tenant management, live chat monitoring, and human handover; HMAC (X-Hub-Signature-256) webhook security with idempotency.
