The channel decides first
The real difference is where the enquiry arrives. An answering service picks up the telephone. An AI receptionist answers visitors on your website. If most of your new customers phone you, a phone service is the fit. If they browse your website first, a chat that answers and books captures them while they are still there.
Coverage and speed
A website chat answers in seconds, all day and night, and can talk to many visitors at once. An answering service is staffed by people, so quality is personal but capacity and hours depend on the provider, and busy periods can mean waiting.
What drives the cost
Phone services commonly charge by minutes or calls, so a busy month costs more. An AI receptionist like Chatdek is a monthly plan with limits on chats, leads and bookings; the plans and their limits are on the pricing page. Compare your own call volume and website traffic rather than headline prices.
When people do it better
Sensitive calls, complaints and complex negotiations belong with a person. That is why a good AI receptionist hands over live, or takes a message, instead of trying to handle everything.
Using both
Many small businesses combine a phone answering option for calls with an AI receptionist for the website. The chat captures leads and bookings from visitors who would not have phoned.
