Creating a multilingual app is challenging. In this demo-heavy session we will use a combination of AI capabilities to help in that workflow. With the help of Large Language Models (LLMs) based services such as ChatGPT, integration in our IDE with GitHub CoPilot, cloud-based translation services like DeepL Translate, or Azure Cognitive Services Translator, and other tools we will build a multilingual app. We are covering different aspects, such as the layout of the app, the "plumbing" of the multilingual components, quickly integrating cloud services, refactoring, and generating custom content for specific audiences. This session will help you to choose best-of-breed tools for generating content and accurate translation including dealing with a specific subject domain, target a specific audience, or incorporate subject matter terminology. We will also give a quick overview of what the respective AI models and services are, and how to get started.
