I need an AI chat agent built from the ground up to take over real-time customer service across a dedicated WhatsApp line. The bot must greet visitors instantly, understand their questions in multiple languages, and return clear, relevant answers without sounding scripted. When the query falls outside its scope, it should hand the conversation to a live agent smoothly while keeping full context. Key expectations • Seamless installation on my existing site (JavaScript snippet or widget) and connection to my verified WhatsApp Business account through the official Cloud API. • Natural, conversational responses in at least English and Spanish to start, with the framework ready to add more languages easily later. • A simple dashboard where I can upload FAQs, product manuals, or policy documents so the model can learn and update itself. • Analytics that log user satisfaction, peak chat times, unresolved topics, and hand-off rates. • GDPR-compliant data handling. Acceptance criteria 1. I can watch you trigger a real chat on the site and on WhatsApp, see the bot reply correctly in two languages, and observe it escalate when asked an unsupported question. 2. I receive the deployment instructions, API keys/environment variables safely documented, and a short video walkthrough of the dashboard functions. 3. All code, fine-tuned models, and configuration files are transferred to my private repo. 4. Trigger Browser and Copy required details and post details again on whatsapp Preferred stack is open, though I am already using Node.js on the backend, so matching that would be a plus. If you have past examples or a quick demo, point me to them—I’m ready to move fast once I see the fit.
