Leora: AI-Powered Voice Sales Assistant

Leora is Leobit’s AI-powered vocal sales assistant designed to deliver instant, tailored responses to potential clients. Unlike traditional chatbots, Leora uses voice interaction and advanced AI to simulate natural conversations, so that prospects or customers can receive the information they need without delay or manual search. Trained on the company’s data and case studies, Leora reflects Leobit’s domain knowledge and service portfolio.

This project showed that AI shouldn’t be used just for its own sake — it needs to solve real business problems. We created Leora to address specific challenges in our sales process, and by using the RAG approach, we ensured the assistant gave accurate, domain-specific answers instead of generic ones. The rapid prototyping allowed us to validate the concept within days and then focus on refining the user experience.
