A business phone line with an AI secretary answering the calls
Beginner
What is KaiCalls?
KaiCalls is a business phone service with an AI secretary named Kai built in. It answers inbound and outbound calls and handles texts, WhatsApp, email and meeting notes on the same line. A free browser preview requires no card, and paid plans start at $10 per month after a $2 first week.
KaiCalls combines two things small teams usually buy separately: a business phone number and a receptionist. The phone line is the product, and Kai is the secretary built into it. Kai handles inbound and outbound calls, and the same number also covers texts, WhatsApp, email and meeting notes, so a single line becomes the front door for most customer contact. Setup begins in the browser. A free preview lets you add a website or business details and listen to how Kai answers before any money changes hands. No card is needed to build and preview the assistant. You pay when you want a real number, and plans start at $10 per month, with a $2 first week. The site also runs a coverage check so you can confirm that your own cell number and the Kai number you want can sit in different countries before you commit. In practice this suits freelancers, solo operators and small service businesses that miss calls while working and cannot justify a full time receptionist. Kai answers, takes messages and passes on leads, and texts keep the same thread. Call forwarding connects your existing line to the Kai number, which is documented separately from the signup flow. Texting is not switched on by default: it needs separate consent and carrier registration, known as A2P setup, so teams that rely on SMS should plan for that step. Callbacks and transfers are still subject to destination restrictions, and local carrier forwarding rules and charges apply. The honest framing is that KaiCalls is a phone service first and an AI tool second. It is a reasonable fit for a business that wants one number with a secretary attached, and a poor fit for someone who only wants a chat widget or a voice agent bolted onto an existing PBX. Calling it a full contact centre would overstate it.
How do you use KaiCalls?
1Run the coverage check
Pick the country of your cell number and the country you want for the Kai number. The preview does not reserve a number or change your signup details, but it tells you whether the pairing works.
2Create the free preview account
Enter an email, password and optionally your cell number, then add a website or business details so Kai has context. Google sign in is also offered. No card is required at this stage.3Listen to Kai answer
Use the browser preview to hear the assistant handle a call before you choose a paid plan. Adjust your business details if the answers miss the mark.4Choose a plan and get your number
Move to a paid plan when you are ready for a real business number. Pricing runs from $10 per month, with $2 for the first week, and can be cancelled anytime.5Forward your existing line
Set up call forwarding from your current number to the Kai number so live calls reach the assistant. Carrier rules and charges apply at your end.
6Enable texting with A2P registration
If you want Kai to handle SMS, complete the separate consent and carrier registration process. Texting stays off until that registration clears.
