# How VIER built a world-class chatbot solution with no-code automation

"Appmixer saved us a tremendous amount of development time. The default UI of the designer looks great and is ready to be used out of the box. However, if you need to make any changes, Appmixer UI SDK offers all the flexibility needed for embedding into your product seamlessly."

About VIER

##### Innovative cloud-based communication platform

VIER provides cloud-based customer communication solutions focused on automation, analytics, and omnichannel services. Their platform helps companies streamline customer interactions, offering tools for contact centers, speech analytics, AI-driven chatbots, and workflow automation. VIER is designed to improve efficiency in both customer service and internal processes, while ensuring data security through its German-based infrastructure.

Their goal

##### Enable customers to build custom chat and voice bots in an intuitive environment

With VIER Dialog Workbench, customers can create chat and voice bots that genuinely understand user input through advanced conversational AI and natural language understanding, rather than relying solely on pre-defined paths. **The goal was to provide a simple, user-friendly interface that allows customers to design any conversational logic they need.**

Chosen solution

##### Great-looking automation designer that gives confidence to even non-technical users

While VIER valued the ability to build custom components (triggers and actions), the real game-changer was Appmixer's visually appealing UI that won over even non-technical users. Through the intuitive automation interface—which integrates seamlessly and feels native to VIER's platform—customers can now design and automate custom conversational logic without needing to write any code.

Success

##### Enhancing customer experience and optimizing sales demos

By integrating Appmixer’s no-code automation designer, VIER empowers customers to easily create tailored chat and voice bots. This solution not only enhances the customers' user experience but also provides sales reps with a persuasive interface for more effective demo calls. **The innovation significantly boosts customer satisfaction, streamlines sales processes, and expands the sales pipeline.** Additionally, by using Appmixer, VIER saved months of costly development time, allowing them to reallocate valuable resources to other strategic projects.
