How it works

NXIVO AI Receptionist

Every missed call costs your business $450 in lost revenue. Nxivo is the AI receptionist that makes sure you never miss one. Nxivo answers every inbound call 24/7 with a natural, conversational voice, books appointments directly to your Google Calendar, and collects payment via Stripe, all during the call, before the caller hangs up. No voicemail. No missed opportunities. Unlike virtual receptionist services that charge per minute or per call, Nxivo offers unlimited calls for a flat $99/month. At 500 calls/month, competitors like Smith.ai cost $1,200+. Nxivo costs $99. Because Nxivo runs on self-hosted AI, not OpenAI or Google APIs, your callers' voice data never touches a third-party cloud. HIPAA-ready for healthcare, compliant for legal, and private for every business. Nxivo automatically detects whether a caller speaks English, or Spanish and responds in their language, no menus, no button presses. Every call is recorded, transcribed, and summarized by AI. Returning callers are recognized by name. Urgent calls are escalated to your team with full context.

OMO AI

OMO AI is a Georgian-language voice AI platform for business phone workflows. It supports use cases such as appointment booking, outbound follow-up, customer surveys and voice IVR, with custom conversation flows designed around a business's rules and connected systems. Appointment workflows distinguish understanding a request, checking current availability, confirming the caller's choice and verifying the result in the destination system. Supported actions depend on the configured integrations, permissions and business process. Exceptions and uncertainty require a defined path to a human. OMO also publishes Georgian and English educational resources on voice-workflow design, Georgian speech technology, testing and human handoff. Its open GitHub checklist and Hugging Face dataset include twelve synthetic booking-safety examples; these are educational resources, not claims of measured production accuracy or uptime. The website provides product information, a knowledge center and a way to request a demo.
