Abby AI Receptionist

Abby AI Receptionist answers your business calls 24/7 in your company's name. It greets callers in a natural voice, answers the questions you have taught it, screens and transfers calls, takes messages, qualifies new leads and books appointments directly into hundreds of scheduling platforms, in English or Spanish, on the phone number you already have. Every conversation arrives moments later as a transcript, AI summary, sentiment score and recording in the AbbyGO app and the my.abby.com portal. Built and trained in-house by Abby Connect on more than 20 years of receptionist calls for over 6,200 businesses, on Deepgram Flux for speech recognition, the latest OpenAI models with automatic failover to Anthropic for understanding, and ElevenLabs for voice. One subscription covers the AI Receptionist and Abby's U.S.-based human receptionists, who all work from Abby's Las Vegas office: you choose how each call is handled, human, AI or a mix, and change it any time. A minute of AI answering counts as half an Abby Minute, so AI stretches the same plan twice as far, and the AI warm-transfers to a human receptionist on the same call for the conversations you flag. Connects with 1,000+ tools, including Clio, Lawmatics, HubSpot, Salesforce and Calendly. Plans from $165 a month, free trial, no setup fee, no after-hours or weekend upcharge.

Agent247

Agent247 is an AI voice agent that lives on your website — not a chat widget, a voice. Drop in one script tag and it comes alive knowing nothing about your site. Every turn, it reads the live page so it always knows exactly what's in front of the visitor. It doesn't just answer typed questions and stop. It talks, and it shows: it greets every visitor the moment they land, in their own language, then walks them through your live product out loud — highlighting what matters, pointing the way, and telling them exactly where to click, like a rep on a screen share. From there it handles objections, points visitors to the right plan, and keeps the momentum going all the way to a completed checkout. Setup takes minutes. You don't need docs or a polished knowledge base to train it — just click through your own product once and talk it out loud, and Agent247 runs that same demo for every visitor after, forever. It works with any stack — Webflow, WordPress, Shopify, Framer, Wix, React — and speaks 100+ languages, so visitors who'd normally bounce because of a language gap get answered instantly instead. It also compounds: every conversation it has teaches it more about who buys, what wins them over, and where deals quietly slip away — so it gets sharper the longer it runs. Agent247 is built for one problem: your funnel leaks the moment nobody's there to answer a question — at 2am, on a "book a demo" form, in a support queue. Agent247 is always there. Currently pre-launch, in early access.

AgentCallback

AgentCallback is a Voice AI platform that manages calls at scale - 24/7, multilingual, always available. Businesses lose revenue from missed calls during weekends, after-hours, holidays, and peak times. Long wait times and complex IVR systems create poor customer experiences and lower CSAT. Companies also face rising costs from agent burnout, high turnover, and hiring. Expanding into new regions requires costly multilingual teams, which makes global scaling harder. AgentCallback solves these challenges with real-time voice AI agents that answer questions, qualify leads, book appointments, run surveys, and route calls. The platform uses speech-to-speech models, enabling voice understanding without traditional text pipelines. This means faster responses, natural conversations, interruption handling, and background noise handling. With low latency and scalable architecture, AgentCallback helps businesses answer every call, deliver consistent global experiences, and scale voice operations at a lower cost.
