Mercedes-Benz needed a secure, compliant internal generative AI tool that could simplify daily knowledge work, provide fast context-aware answers, and support cross-functional collaboration without exposing personal or sensitive data.
Reported impact
Direct Chat became an established internal AI platform across the organization, giving employees reliable support for writing emails and reports, summarizing documents, accessing internal knowledge, and collaborating across international teams in a secure and compliant environment.
Mercedes-Benz Group built Mercedes-Benz Direct Chat as an internal web application for enterprise generative AI use. Employees submit prompts through the Direct Chat interface, which was originally based on OpenAI's ChatGPT technology and is integrated through Microsoft Azure OpenAI Service. This gives the company a managed environment for running LLM workloads with Azure security, privacy, and reliability controls. In 2025, Mercedes-Benz added Google Gemini so users can choose between multiple AI models, and it added DALL.E for image generation and image analysis inside the same experience. Mercedes-specific knowledge agents connect the chat experience to internal systems so the application can return tailored answers from company content and act as a central information platform. The solution is served in English and German, hosted in European data centers, processes employee prompts anonymously, and is governed by internal data protection policies and AI usage guidelines rather than storing sensitive data for model training.
Employees enter prompts in Mercedes-Benz Direct Chat, which routes requests through Microsoft Azure OpenAI Service to ChatGPT or Gemini, with DALL.E handling image generation and analysis tasks. Mercedes-specific knowledge agents retrieve relevant context from internal systems and return tailored answers in the same chat interface. Inputs are processed anonymously, and operations are hosted in European data centers.
"All operations are hosted in European data centers, with Mercedes-Benz retaining full control over the underlying IT processes."
"Employee text inputs are processed anonymously, and no personal or sensitive data is stored or used to train AI models."
"Mercedes-specific knowledge agents provide tailored insights from internal systems, making Direct Chat the central information platform for internal content and cross-functional collaboration."
"More than 10,000 employees use Direct Chat daily as power users."
"New features such as image generation and analysis using DALL.E are now also available directly within the chat."
"One of the tools the company relies on to simplify daily processes and boost efficiency is the Mercedes-Benz Direct Chat."
"The application is integrated via the Microsoft Azure OpenAI Service, combining the power of large-scale generative AI with Azure’s robust security, privacy and reliability features."
"This AI-powered chatbot is based on OpenAI’s ChatGPT technology and delivers precise, context-aware responses within seconds."
"With its latest update in August 2025, Direct Chat has become even more powerful – thanks to the integration of Google Gemini, employees now have access to multiple AI models depending on their needs."
