Localization

This content is for v1.x. Switch to the latest version for up-to-date documentation.

The widget ships English (en), Spanish (es), French (fr), and German (de) UI strings.

Locale resolution

Explicit locale option, if set
<html lang> attribute of the host page
navigator.language
Fallback: English

Region subtags are normalized (fr-CA → fr); unknown languages fall back to English.

window.ClaudiusConfig = {
  apiUrl: "...",
  locale: "de", // force German regardless of page/browser language
};

Overriding individual strings

translations merges over the resolved locale, so you can override just the strings you care about:

window.ClaudiusConfig = {
  apiUrl: "...",
  locale: "es",
  translations: {
    title: "Soporte PMDS",
    welcomeMessage: "¡Hola! ¿En qué puedo ayudarte hoy?",
  },
};

Note these localize the widget UI only. The AI’s reply language follows the conversation and your system prompt — instruct the bot there if you want replies pinned to a language.
