AI Support Chatbox Integration

I need an AI-driven chat widget embedded into my SaaS platform that can greet visitors, field routine questions, and then, on explicit customer request, hand the conversation over to a live agent. The core focus is customer support, not sales or technical troubleshooting.

Here’s what I’m after:

• Smart dialog flow that recognises intent, answers simple queries, and clearly offers a “talk to a human” option.
• Seamless, real-time handover the moment a user selects that option, with full conversation history passed to the agent.
• Lightweight front-end widget that drops into my existing app with a single JavaScript snippet and can be styled to match our branding.
• Back-end logic (Node, Python, or similar) wired to an LLM or NLP service of your choice, plus a webhook/API endpoint for the live-agent system I already use.
• Admin dashboard or config file where I can tweak canned responses and view basic transcript logs.
• Installation guide and brief documentation so my dev team can maintain it going forward.

Acceptance criteria: widget loads inside the SaaS app without performance hit, answers at least 80 % of a supplied FAQ set in testing, and hands off instantly (≤2 s) when a user clicks “speak to a human.”

If you’ve built AI support bots with human handover before, especially using Dialogflow, Rasa, or an OpenAI stack, I’d love to see an example.
