What does a conversation handled by the AI look like?

Example conversation

Burger joint AI agent

Customer: How much is the double smash combo?

AI agent: The double smash combo is your price.

Customer: Can you take off the onion and add bacon?

AI agent: Sure. Noted: no onion, with bacon. I'll confirm item by item with you.

An example built from the questions on this page, not a real customer. The highlighted parts are what you write in the Brain: price, hours and your business's rules.

Is an AI agent or manual service better for burger joints?

The agent wins at repetitive tasks, and people keep winning at what takes judgment. With manual service someone at the burger joint 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
Order full of variations: doneness, extras, removals	"No onion, extra bacon" gets lost in the grill rush	Built item by item and confirmed in writing before production
Answering at the rush	Customer waits ten minutes and orders from a competitor	Immediate reply even with a full digital queue
Combos and the day's promotions	Explained one by one, in every conversation	Menu and combos answered automatically, always up to date
"Where's my burger?"	Whoever is on the grill stops to answer	In production or out for delivery, answered without stopping production
Customer who vanished	Customer base sitting idle, nobody reaching back out	Messaged with their favorite combo after weeks without ordering
