known_gaps:
  - Vendor-reported automation, handle-time, and satisfaction metrics need deployment-specific evidence before being cited.
  - Customer-facing systems need guardrails for policy accuracy, escalation, privacy, and human review.

## TL;DR

AI customer service is best treated as a set of support workflows, not one automation claim. The strongest evidence supports retrieval-grounded chatbots, live agent assistance, and post-interaction analytics, while vendor performance claims need separate validation.

## Core Explanation

A customer-service chatbot is useful only when its answer is tied to the organization's actual policies, product documentation, or ticket history. Retrieval-augmented generation is one common pattern: retrieve relevant support material first, then generate an answer constrained by that material.

Agent assist is a different workflow. Instead of replacing the support agent, the system watches the conversation context and surfaces relevant knowledge, suggested responses, or next actions. That creates a timing and relevance problem: suggestions must arrive quickly enough to help, and weak suggestions can distract the human operator.
