Integration of AI Chatbot for Customer Support

Customer support has become a bottleneck in our growth. The subscription platform now has over 5000 active users, and the volume of repetitive queries has grown to the point that support operators spend most of their time answering FAQ questions instead of handling complex issues that require real intervention. We want to implement an AI chatbot that autonomously handles standard questions, learns from our knowledge base, and correctly escalates unresolved situations to live operators — all within our existing PHP platform.

The solution should include a dialogue scenario builder that the non-technical support team can update without involving developers, a FAQ knowledge base editor with categorization and version history, and a chat widget embedded in the user dashboard without affecting page performance. Required: multilingual support (ru/en) and an analytics dashboard with key metrics — response rate, resolution rate, and CSAT — to measure bot effectiveness and continuously improve its performance.

Technical requirements:
— Integration with PHP 8 backend via REST API
— Dialogue builder (visual or configuration-based)
— FAQ knowledge base editor with versioning
— Escalation: routing unresolved queries to operators
— Chat widget in dashboard without affecting performance
— Multilingual support (ru/en)
— Analytics: response rate, resolution rate, CSAT, top unanswered questions

Stack: PHP 8 backend, Vue.js or React widget, AI provider by agreement (OpenAI, Claude, etc.).
