AI for Customer Support

AI is reliably handling 30-70% of tier-1 volume now. The wins come from tight knowledge-base hygiene, escalation rules, and feedback loops on every resolved ticket.

What it looks like in practice

Customer messages an agent in chat or email. The agent retrieves from your help center, answers, takes account-modifying actions through scoped tools, and escalates to a human with full context when stuck.

Where AI is strong

  • FAQ and policy questions
  • Account lookups
  • Ticket triage and tagging

Where AI still struggles

  • Empathy-first conversations
  • Edge cases not in the KB

What to measure

  • First response time
  • Containment rate
  • CSAT
  • Escalation rate
