AI Customer Support Chatbot Integration -- 3

I need an AI-powered chatbot built to handle frontline customer support, specifically technical support questions, and to slot seamlessly into both my website and our existing mobile app.

The bot should recognise common troubleshooting queries, guide users through step-by-step fixes, and escalate to a human agent whenever confidence is low. I am open to the underlying NLP stack—Dialogflow, Rasa, Microsoft Bot Framework or a comparable solution—as long as it can be trained on my product documentation and log conversations for continuous improvement.

Key deliverables:
• Fully trained chatbot deployed on web and mobile app SDKs
• Clear hand-off logic to live agents, with context preserved
• Admin dashboard or API hooks so my team can update intents and review analytics
• Brief hand-over guide plus code repository

Please factor in future extensibility to social-media channels, but for now the focus is just website and mobile. If you have shipped similar customer-support bots before, I’d love to see a quick demo or link.
