| Customer chatbot for **web** (WhatsApp-ready): grounded RAG | |
| answers, lead capture, appointment slots, and human handoff. | |
| **Demo claim:** 60% of questions handled without a human, | |
| appointment booking 24/7. | |
| ## Demo business | |
| Fictional SME **Nordic Paper Solutions** (FAQ EN / FR / RU). | |
| Safe for demos — no real customer data. | |
| ## How to use | |
| 1. Open **Live demo** and ask about products, pricing, delivery. | |
| 2. Try booking a call (demo slots if Cal.com is not set). | |
| 3. Check **Dashboard** for conversations and KPIs. | |
| ## Space secrets | |
| In **Settings → Variables and secrets**, set: | |
| | Name | Value | | |
| |------|--------| | |
| | `OPENAI_API_KEY` | your OpenAI key (**Secret**) | | |
| | `OPENAI_MODEL` | `gpt-4o-mini` | | |
| Optional: `CALCOM_*`, `WHATSAPP_*`, `HANDOFF_WEBHOOK_URL`. | |
| Without OpenAI the UI still works (demo grounded answers). | |
| With OpenAI, chat replies use the LLM; retrieval stays local | |
| so the Space starts fast on Hugging Face. | |
