terminio.ai is an AI-powered appointment booking and phone assistant software for service-based businesses. It integrates booking management, payment processing, customer communication, and call handling into one system. Customers can book appointments anytime via a customizable online page without an account. Businesses set up services, pricing, and staff assignments, with the system calculating availability automatically. Booking links can be shared through Instagram, Google profiles, WhatsApp, or QR codes. The AI phone assistant answers calls, checks availability, and books appointments while logging call summaries. Stripe integration allows businesses to collect deposits or full payments during booking, and WhatsApp reminders send confirmations and pre-appointment messages. The platform supports team management with shared calendars and role assignments. Accessible via web, mobile apps, and smartwatches, terminio.ai ensures GDPR compliance and uses EU-based hosting.
