Umni published 3 case studies for customer’ chatbots from 3 different industries and business types. What they have in common is that the chatbots save staff time, help with customer service, extend working hours, and automate routine tasks. An interesting fact is that an average of 35% of users communicates with the chatbots of the businesses at night. Here is a summary of the 3 chatbots from Umni:

Ellie, the chatbot of the Varna Regional Library, is integrated with the electronic catalog of the library. The bot answers frequently asked questions and allow readers to re-assign books at any time of the day. Ellie “extended” the working hours of the library and successfully replaced the employees after 17:00. 3 months after activating the chatbot, re-assigning the borrowed books is the function most actively used by users. In March 2020, Ellie handled 30% of the requests. After the activation of Ellie, there is an exponential increase in communication between readers and the library in messenger. The case study here.
