Start with the work that’s piling up.
Keep your number. Connect your mailbox. Add the services you need.
First, see a call handled.
A caller becomes a saved contact, a clear summary and a next step. Watch the actual product, from picking up to following through.
Start with the calls you miss.
Keep the number they know.
Keep your number.
Nothing to port. Customers dial the number they already have, on the phones you already use.
Setting up a number in four steps: pick (512) 555-0168, choose rings you first, then Kai, switch on forwarding for the calls you don't pick up, and place a test call. The test call passes and the number is ready.
Your phone rings first.
Forward only the calls you don’t pick up. Forward-all would send Kai every call and your own phone would stop ringing.
A call from Maria, (512) 555-0142, rings your phone three times and you can't pick up. Kai picks up for Williams Plumbing, takes down what Maria needs, texts you a summary and saves her as a lead. The call ends answered.
Kai takes the work.
Kai gets the name, the job, the address and the timing, and answers the common questions.
A short call with Dave appears line by line. He has a water heater leaking in the garage and wants someone out tomorrow morning. The transcript folds into one line under What they wanted, which drops into a lead card for Dave marked Hot.
You get a text.
The details land on your phone, ready for you to call back and book the job.
Your linenowHot lead: Dave needs a drain cleared before Tuesday. Kitchen sink, second time this year. Call back today.

Your number is one place to start. Connect email, add campaigns and bring Kai into your meetings when you’re ready.

A clock runs from 5 PM to 8 AM. After closing time four calls come in, at 6:12 PM, 8:40 PM, 11:05 PM and 6:30 AM, and Kai answers each one. In the morning view all four calls are listed as answered, with what each caller needed.

Why it costs less than an answering service
No call center
There's no room full of operators to pay for. That cost never lands on your bill.
Kai answers every call
Day or night, Kai picks up, takes the details, and gets them to you.
No per-minute charges
Kai Line is $79 a month, flat. A long call costs the same as a short one.
Need a different size? Kai Backup is $10/mo and Kai Office is $349/mo. See every plan
