About

LobbyStack is open-source AI receptionist software for small businesses. It answers inbound phone calls, handles SMS, captures messages and caller details, books, reschedules, and cancels appointments, answers questions from business knowledge, and transfers conversations to a person when needed. Teams manage business hours, services, availability, knowledge, calls, transcripts, recordings, tasks, appointments, and customer conversations from one web dashboard. Use LobbyStack as a hosted cloud service or self-host the AGPL-3.0-only source code. Current product information, documentation, and pricing are available from the product homepage.

About

Nextiva XBert is Nextiva's AI employee for customer conversations, an AI-powered answering service, receptionist, and support agent that handles calls, texts, chats, and emails 24/7. It greets callers, answers questions, books and reschedules appointments, captures lead details, and resolves routine issues without human intervention, escalating only when a situation is too complex or sensitive for AI to handle alone. XBert trains itself on your business by pulling in your website, services, hours, and FAQs, then keeps improving from every real interaction. It unifies voice, text, and chat into one conversation thread, so context carries across channels. Built on Nextiva's enterprise-grade platform, it offers PCI DSS, HIPAA, and GDPR compliance, full call recording/transcription, and customizable guardrails for what it can and can't do. Pricing starts around $99/month for a set number of AI conversations, with setup available in minutes, no coding required.

Audience

Small businesses, local service companies, clinics, salons, repair shops, consultants, agencies, home service teams, and appointment-based businesses that need an AI receptionist to answer calls, reply to texts, manage bookings, and handle customer follow-ups.

Audience

Home services (HVAC, plumbing, electrical, landscaping) — techs are out in the field and can't answer calls, but customers calling about a broken AC unit rarely leave a voicemail; they call the next company. XBert answers, books the job, and keeps the pipeline full. Medical, dental, and other appointment-based practices — front desk staff get slammed during business hours and can't cover after-hours or lunch. XBert schedules, reschedules, and answers routine patient questions, with HIPAA compliance built in. Restaurants — handles reservation calls, menu questions, and hours inquiries without pulling staff off the floor during a rush. Real estate teams and agents — captures lead details and qualifies interest on inbound calls/texts about listings, even when an agent is mid-showing. Small businesses and solo operators generally — anyone running a business on one phone number who can't afford (or doesn't need) a full-time receptionist but still loses revenue every time a call goes unanswered. Growing businesses layering AI onto an existing setup — companies already on Nextiva's phone/contact center platform that want AI handling routine volume so human agents can focus on higher-value or more sensitive conversations.
