smao

smao is a cloud-based AI phone assistant that handles first-level support calls around the clock, ensuring no caller ever hears hold music or busy signals. Hosted entirely in EU data centers, it guarantees 100 % GDPR compliance and keeps all voice data securely within Europe. At its core, smao relies on a fully customizable knowledge base and glossary. You simply upload FAQs, product guides and internal terminology, and smao uses that structured content to deliver accurate, on-brand answers to routine inquiries without any human intervention. If a question falls outside its scope, smao’s intelligent call routing engine steps in. Based on rules you configure, it automatically forwards complex issues to the right department or agent, complete with caller context and transcript. Callers enjoy a seamless experience thanks to DTMF-driven menus that let them enter PINs, account numbers or menu selections directly on their telephone keypad. This removes friction from authentication and self-service workflows. Behind the scenes, every conversation is transcribed and analyzed in real time for sentiment, keywords and resolution paths. That data is turned into tickets or reports and pushed into your existing systems, so you can track support performance without any manual effort. smao currently supports German, English, French, Italian and Swiss German, with other languages available upon request. One-click integrations connect smao to more than 20 popular platforms—including HubSpot, Freshdesk, Jira Service Desk, Zendesk, Salesforce Service Cloud, Microsoft 365, Slack and cal.com—so transcripts, tickets and call data flow directly into your workflows within minutes, with no coding required. By automating up to 60 % of repetitive calls, smao frees your support team to focus on higher-value work and strategic initiatives. Response times shrink to under five seconds, even during peak traffic or holidays, boosting customer satisfaction and loyalty. Real-time dashboards give you complete visibility into call volumes, peak periods, frequently asked questions and routing success rates. Those insights help you continuously refine your support strategy, reduce operational costs and achieve a rapid return on investment. smao scales seamlessly from small offices handling a handful of daily calls to large contact centers processing thousands of interactions without adding headcount or hardware. Setup takes only a few clicks, and an intuitive web interface lets you manage knowledge content, routing rules, access permissions and reporting without IT involvement. Role-based permissions and multi-tenant isolation ensure that each department or subsidiary sees only the data and functionality that matters to them.
