OrapexAI

OrapexAI is a 100% HIPAA-compliant AI voice receptionist built exclusively for dental practices. It integrates in real-time with Open Dental using secure API keys to book appointments, verify patients, and map insurance directly during live calls. The AI agent answers inbound calls 24/7, verifies existing patients using first name, last name, and date of birth via fuzzy matching logic, and automatically generates new patient profiles. During the call, the AI checks live provider and operatory availability, books the appointment directly into the PMS, and automatically assigns the correct procedure codes (like D0120 or D1110). Furthermore, OrapexAI collects and appends primary and secondary dental insurance information directly to the patient profile without overwriting existing claims. OrapexAI operates under a signed Business Associate Agreement (BAA) and never uses Protected Health Information (PHI) for AI model training.

Otto

Otto is an AI voice assistant built specifically for restaurants, cafes, takeaways, pubs, and hospitality venues that need to automate their phone systems without adding to their headcount. It works with your existing phone number and handles incoming calls the same way a staff member would, just without tying up your team. Built by hospitality tech veterans who understand how fast paced and understaffed service gets, Otto was designed from the ground up to help venues stop missing calls and start recovering revenue. Key Features & Functionality - AI-powered phone answering that picks up every call within 2 rings, 24/7, 365 days a year - Takes full takeaway orders and sends them directly to your kitchen via KDS, kitchen printer, or POS system - Books, modifies, and cancels reservations including group bookings, functions, and event enquiries including deposit collection and guest qualification - Answers customer questions about menus, hours, allergens, parking, holiday trading, and general enquiries - Handles customer complaints by following your resolution playbook, resolving common issues on the spot, and escalating with a full structured report only when necessary - Concurrent call handling so multiple customers can be served simultaneously with no busy signal - Real-time menu reading, order confirmation, and upselling of sides, drinks, and add-ons during live calls - Multilingual support across 3 to 10+ languages depending on plan - Customer memory that recognises returning callers and personalises their experience (Pro and Unlimited plans) - Seamless human handoff for complex calls that need a staff member - Call transcripts and analytics across all plans, with advanced reporting on higher tiers - KDS software and kitchen printer included with every plan, no additional hardware required - Fully customisable voice, tone, scripts, menu logic, and operating rules to match your venue - Works with existing phone numbers, no hardware overhaul required, most venues live within one business day Primary Value & Problems Solved Otto exists to solve one of hospitality's most persistent and costly problems: missed calls. During peak service, staff are on the floor, the kitchen is moving, and the phone keeps ringing with no one free to answer it. Every missed call is a missed order, a lost booking, or a customer who hangs up and orders elsewhere. Otto eliminates that problem entirely by acting as a fully autonomous phone operator that runs alongside your existing team. It doesn't replace staff, it takes the phone off their plate so they can focus on in-venue guests. Venues using Otto see a 43% upsell rate on add-ons and sides during live calls and a 99.9% order accuracy rate. The result is more revenue captured, more consistent customer experiences, and a team that isn't constantly pulled away from the floor to answer calls. Who It's For Otto is built for hospitality operators across Australia running restaurants, cafes, takeaways, pizza venues, pubs, and bars. It suits venues of all sizes that take phone orders or reservations and are losing revenue to missed calls or tying up staff on the phone during service. It is particularly well suited to busy venues with high call volumes during peak trading periods like Friday and Saturday nights. How It Works Otto plugs into your existing phone number and is configured using your menu, seating rules, and brand preferences. When a call comes in it routes straight to Otto, who handles the conversation end to end. Completed orders go directly to the kitchen, bookings are confirmed to the guest and the team, and any calls that need a human are transferred cleanly with full context. Most venues are live within one business day with no technical setup or hardware changes required.
