Your business phone number, powered by AI.

Kai Calls is a phone service with a built-in secretary. Your business number can answer, remember caller details, follow up, and brief you when you call Kai and ask what happened.

Voicemail just records messages — 73% of callers hang up without leaving one. Answering services put callers on hold and cost $1,500-3,000/month. Kai answers every call instantly, has real conversations, qualifies leads, books appointments, and texts you the details. Plus, you can call Kai anytime to get a briefing: “Hey Kai, who called today?” No app needed.

Plans start at $69/month for 150 minutes. What enterprise companies pay $3,000+/month for — now accessible to every small business. No setup fees, no contracts, cancel anytime. 7-day free trial included.

Forward calls to Kai or use a KaiCalls number. The number answers, captures intent, routes or follows up when configured, and sends the owner a summary. You can also call Kai and ask what happened.

Yes. You keep your current phone number. Just forward calls to Kai — takes 2 minutes. Your customers call the same number they always have. Works with any phone system including landlines, VoIP, and cell phones.

KaiCalls scopes account access by business, validates provider webhooks, and treats consent, opt-outs, DNC, calling hours, and rate limits as operating rules. We do not claim SOC 2 or HIPAA certification unless and until those certifications are verified.

No. That's the whole point. Just call Kai from your phone. “Hey Kai, who called?” “Hey Kai, send them a text.” There's a dashboard if you want it, but you never need to open it. Less screens. More talking. More stuff getting done.
