What does a conversation handled by the AI look like?
Example conversation
Jewelry store AI agent
Customer: How much is a pair of 18k gold wedding bands?
AI agent: To quote the bands, tell me the model, the sizes and whether you want engraving. I'll organize everything for the store.
AI agent: If you'd rather see them in person, I'll book a time at the store for you.
Is an AI agent or manual service better for jewelry stores?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service someone at the jewelry store has to stop what they're doing; with the CertuAI agent the reply goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Custom wedding band quote | Answered hours later, and the high-value sale cools off | Model, material, size and engraving collected right away |
| "Is my repair ready yet?" | Customer asks every week and someone checks at the workbench | Status answered on its own and automatic notice on completion |
| 18k gold versus gold-plated | The same explanation given a thousand times, differently each time | Materials, warranties and care explained consistently |
| Closing the consultative sale | Conversation dies on WhatsApp with no invitation to the store | Visit offered and booked, where your consultation closes the sale |
| Customers' anniversaries and birthdays | Dates go by unnoticed and the gift is bought elsewhere | Date saved on the record, and you open the task whenever you want |
