Frequently asked questions
What is an AI setter?
An AI setter is an AI agent that does the appointment-setter job: replying to prospects, qualifying them, handling objections and booking calls on your calendar.
Is an AI setter better than a human setter?
It is faster and never off shift, so no reply waits. Many teams pair it with a human closer, and keep approvals on for high-value replies.
Can it qualify leads before booking?
Yes. Give the agent your reply rules and knowledge base, and set which categories auto-send or need approval, so only the right leads are offered times.
What happens with unqualified leads?
They get a polite, on-brand reply and the thread is categorised, so your calendar only fills with the right calls.
How is it priced?
Plans start at $60 a month with unlimited agents and team members. Start with 50 free credits, no credit card.
