Gleap for service businesses
What is AI customer service for service businesses?
It is an AI agent that answers your customers' calls and messages around the clock, books appointments, answers questions about prices and opening hours and handles billing, and gives the rest to your team. In Gleap, Kai Support does this on the phone with Kai Voice and in chat, email and WhatsApp, from one knowledge base and one inbox.
Can Kai answer our phone like a receptionist?
Yes. With Kai Voice Kai answers your phone line, says it is an AI, answers from your knowledge, books appointments and hands calls to your team in the browser. Get a local number in the dashboard or forward the number you have.
Which calendars and billing tools does it work with?
Calendly and Cal.com for appointments; Stripe, Paddle, Chargebee, Lemon Squeezy and RevenueCat for billing. Kai explains charges, sends the billing portal, retries payments and pauses or resumes plans when the customer confirms. Refunds and cancellations go to your team as one card.
How much does it cost?
Plans start at $29 a month billed yearly; Kai Voice comes with Team at $149 a month billed yearly. Phone calls cost $0.20 per started minute and numbers $5 a month, with the first included on Pro. In chat, email and WhatsApp we estimate under $0.05 per resolution (how we estimate). Every plan starts with a 7-day free trial.
How long does setup take?
Minutes. Kai reads your website while you sign up, so it knows your services, prices and opening hours. Get a number or forward yours, connect your calendar and billing tool, test Kai with your own questions, then turn it on.
What happens when Kai can't help?
It hands the call or conversation to the right teammate with a short brief: what the customer needs, what Kai already did and what comes next. Calls ring your team in the browser; nobody has to ask the customer to repeat themselves.
Is Gleap an alternative to fonio?
Yes, when you want more than the phone: Kai Voice answers your calls and the same Kai answers chat, email and WhatsApp in one inbox. See the fonio comparison and the AI receptionist.
