FAQ

Will AI replace human support agents?

Not entirely. AI handles routine inquiries (60-70% of volume), freeing human agents for complex, emotional, and high-stakes issues. The best support combines AI efficiency with human empathy.

How do I prevent AI from giving wrong answers?

Train on verified, up-to-date documentation. Set confidence thresholds — if the AI isn't confident, escalate to human. Review AI conversations weekly and correct errors in the knowledge base.

What's the ROI of AI customer support?

If you handle 1,000 tickets/month at $10/ticket and AI resolves 50%, you save $5,000/month. Most AI support tools cost $100-500/month. ROI is typically 10-50x.

The Bottom Line

For most companies in 2026:

1. Intercom Fin if you want the highest AI resolution rate
2. Freshdesk if you want the best value
3. Help Scout if you're a small team
4. Chatwoot if you want open-source

Start by building a comprehensive knowledge base — every AI support tool performs better with better documentation. The AI is only as good as the content it's trained on.
