What does a conversation handled by the AI look like?
Example conversation
Cake shop AI agent
Customer: How much is a cake for 30 people?
AI agent: To put the quote together, tell me the batter, the filling, the decoration and the date.
Customer: Do you have availability for next Saturday?
AI agent: I'll check the order calendar. If Saturday is full, I'll offer you the next opening.
Is an AI agent or manual service better for cake shops?
The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service someone at the cake shop 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 cake quote | Answered hours later, hands deep in dough, and the customer has already shopped around | Size, filling, theme and date collected right away, order ready to price |
| Order calendar | Notebook with the same date double-booked in a full week | Per-date limit respected, next opening offered when it fills up |
| Order deposit | Agreed by word of mouth, customer vanishes and the cake is left over | Policy explained in writing and order confirmed only after what was agreed |
| Pickup | Customer forgets and the cake waits in the fridge | Automatic reminder the day before, with address and time |
| Ready-to-go items of the day | Sweets and slices announced one by one to whoever asks | The day's menu answered right away, in every conversation |
