- Audit your help center and FAQ content
- Fill gaps in your documentation
- Write clear, concise answers to common questions
- Include examples and edge cases
- Update content regularly
2. Define Clear Escalation Paths
AI should know when to hand off to humans:

Track these metrics to optimize your AI customer service:
- Resolution rate: Percentage of issues resolved by AI

4. Continuously Improve
AI customer service gets better with iteration:
- Review AI conversations weekly
- Identify common failure patterns
- Update training content based on gaps

- Add new capabilities over time
5. Be Transparent
Customers appreciate honesty about AI:
- Let customers know they're talking to AI
