VIA — Multi-Channel AI Brain

IDeaLife's AI Sales Assistant couldn't hold context across Facebook, Instagram, WhatsApp, and the website, didn't know live product or application data, and couldn't move leads forward — so inquiries stalled and sales were lost.

A single AI-powered 'VIA' brain that every channel calls. It detects intent, looks up the client, application status, and the right product, retrieves grounded answers from a Supabase vector knowledge base, replies with per-user memory, advances the lead through the pipeline, and hands off to the booking workflow when ready.

1. 1📥 When called by channel — one shared entry point for FB, IG, WhatsApp & web
2. 2🧹 Normalize Input — unifies every channel's payload into one schema
3. 3🙋 Human-Mode Check — stays silent when a human agent takes over the chat
4. 4🎯 Detect Intent + locale — routes the conversation correctly
5. 5🔎 Client / Application-Status / Product lookups — pulls live data per user
6. 6🛍️ Recommend Products — matches the right product to the inquiry
7. 7🤖 VIA AI Agent — OpenAI answering with Window Buffer Memory + KB Vector Store + Embeddings (RAG)
8. 8🧠 Save Memory — keeps conversation context per user across messages
