AI support assistant

An agent that closes 70% of tickets without a human. RAG over the knowledge base.

NDA project. An LLM + RAG support system: classification, answers to common questions, routing of complex ones.

Challenge

The client's support team was buried in routine questions - response times slipped and quality dropped. The goal was to cut manual load without losing control of the customer conversation.

Approach
  • Connected an LLM to the client knowledge base via RAG for accurate answers to common queries.
  • Designed the pipeline: classify → search the KB → generate an answer with a confidence score → escalate to a human.
  • Built an agent interface: the system suggests an answer, the operator edits and sends it - human-in-the-loop.
  • Added failure analysis so every Q&A pair feeds back and improves the system.
