Activ8 SMS is a messaging and scheduling application designed for service businesses and marketing agencies. Its primary function is to automatically send text replies to new customer enquiries from the user’s own mobile phone number and to use an artificial intelligence assistant to answer questions and book appointments directly into the user’s calendar. The system is intended to reduce response time and prevent leads from being lost while the business owner is occupied with other tasks. The application works by connecting to an Android phone via a QR code scan, allowing it to send and receive messages using the phone’s existing SIM card and mobile number. Users do not need to obtain a new phone number or install additional hardware. After the initial connection, a guided setup process, which the website states takes about ten minutes, allows the user to teach the AI assistant about their business, including common questions, pricing, and availability. Once activated, the AI can handle incoming enquiries, send follow-up texts, and confirm bookings without manual intervention. The service also supports integration with WhatsApp through a similar QR code linking process. Key capabilities include immediate text responses to new enquiries, automated appointment booking, and the ability to operate during evenings and weekends if configured. The platform does not charge per-text fees; instead, it offers a 14-day free trial without requiring a credit card, and the AI assistant is free for the first seven days. The system is built to work with the tools a business already uses, such as existing calendars and phone numbers. Typical use cases involve service businesses like hair salons, tradespeople, or medical practices that receive enquiries via phone or web forms and need to respond quickly to secure bookings. The workflow consists of three steps: connecting the Android phone, teaching the AI the business’s information, and switching on the automated reply and booking feature.
