**[Asyntai](https://asyntai.com)** adds an AI chat assistant to your Vaadin app. It answers your users' questions from your own content, such as your help center, docs and FAQs, in more than 80 languages, day and night. Add the dependency, then set your widget ID in `application.properties`: ```properties asyntai.widget-id=asyntai_1a2b3c4d5e6f ``` The chat bubble is then on every view, with no code. You can also add it from Java: ```java add(new AsyntaiChat("asyntai_1a2b3c4d5e6f")); ``` The assistant can know who is signed in, so its answers fit each user: ```java add(new AsyntaiChat("asyntai_1a2b3c4d5e6f") .setUserContext(Map.of("name", user.getName(), "plan", user.getPlan()))); ``` The chat stays open when users move between views, and the widget loads after your page, so your app always renders first. Works with Vaadin 24 and 25, with or without Spring Boot. Full guide: https://asyntai.com/documentation/integrations/vaadin/
