‍

What is generative AI (GenAI)?

Generative AI refers to AI systems capable of creating new content, text, images, code, and more, rather than simply analyzing existing data or following predefined rules.

Key features :

• Create original answers (not pre-written templates)
• Understands the context and nuances of natural language
• Learns from massive amounts of data
• Adapts to different situations and tones
• Continuously improves with every interaction

Examples of GenAI models :

• GPT (OpenAI)
• Claude (Anthropic)
• Mistral
• Gemini (Google)

At Klark, we use the best GenAI models on the market to power our customer service solutions.

GenAI vs traditional AI: what's the difference?

Example:

Traditional Chatbot: "To track your order, click here : [link]"

GenAI Assistant: "I can help you track your order! I see you ordered the Blue Widget on March 15. It was shipped yesterday and should arrive tomorrow before 2pm. Would you like me to send you a tracking link or reschedule delivery?"

Can you see the difference? GenAI understands the context, accesses the relevant data, and responds naturally.

Best practices for GenAI customer service

1. Start with high-impact, low-complexity use cases

Don't try to automate everything at once. Start with :

• FAQ answers
• Order tracking
• Password reset
• Basic troubleshooting

Then expand to more complex scenarios.

GenAI is powerful, but not perfect. Always :

• Review AI-generated answers periodically
• Human management of sensitive situations

• Monitor for errors or bias

3. Customize to your brand voice

GenAI can be adapted to any tone:

• Formal and professional (banking, legal)
• Casual and friendly (startups, lifestyle)
• Empathetic and caring (healthcare, support services)

Make sure your AI sounds like YOUR brand.

4. Ensuring transparency

Be honest with customers:

• Let them know when they're talking to the AI
• Make human climbing easy and obvious
• Explain how their data is used

Transparency builds trust.

5. Continuous improvement

GenAI should improve over time:

• Analyze failed interactions
• Update the knowledge base regularly
• Refine responses based on feedback
• Testing new capabilities

6. Prioritizing data security

GenAI processes sensitive customer data. Ensure :

• RGPD Compliance
• Data encryption
• Secure API integrations
• Regular safety audits

At Klark, we're SOC 2 certified and RGPD compliant. Security is non-negotiable.

Solution: Focus on increase, not replacement

• Show how AI takes the hard work out of the equation
• Highlight productivity gains
• Involve the team in testing and feedback
• Celebrate victories together

Challenge #3: "We don't have a good knowledge base".

Solution: Start with what you have

• Use past support conversations (gold mine!)
• GenAI can help organize and structure knowledge
• Build incrementally over time

Challenge #4: "It's too expensive".

Reality: GenAI delivers massive ROI

• 30-40% reduction in operating costs
• 50-70% increase in productivity
