AI-Powered Customer Support Chatbot Integration

Customer support is the bottleneck that limits our growth. Our subscription platform now serves over 5,000 active users, and the volume of repetitive support requests has reached a point where human agents spend most of their time answering the same FAQ questions instead of handling complex issues that genuinely need attention. We want to implement an AI-powered chatbot that handles routine inquiries autonomously, learns from our knowledge base, and gracefully escalates anything it cannot resolve to a human operator — all integrated seamlessly into our existing PHP platform.

The solution should include a visual or configuration-based conversation flow designer that our non-technical support team can update without developer involvement, a FAQ knowledge base editor with categorisation and version history, and a chat widget that embeds cleanly into the user dashboard without affecting page load performance. Multi-language support for Russian and English is mandatory. The analytics dashboard must track response rate, resolution rate, and CSAT scores so we can measure ROI and continuously improve the bot's performance over time.

Technical requirements:
— Integration with existing PHP 8 backend via REST API
— Conversation flow designer (visual or YAML-based configuration)
— FAQ knowledge base editor with categories and version history
— Escalation logic: auto-route unresolved queries to human support queue
— Chat widget embedded in user dashboard (no performance impact)
— Multi-language support: Russian and English minimum
— Analytics: response rate, resolution rate, CSAT, top unanswered questions

Stack preferences: PHP 8 backend, Vue.js or React widget, AI provider flexible (OpenAI, Claude, or similar).
