DataMind Oda works in English today. This page explains how Oda chooses the language it runs in, and what you can change in the app.
Oda always runs its interface in English, whatever the language of your computer or browser is:
Oda also marks its interface as English, so screen readers and other assistive tools read the text as English.
There is no language setting today: Settings > General shows no Language row, so there is nothing to pick. General settings covers the page and the settings it has.
No. Oda works in English today, and there is no setting that changes it. Chat with Oda covers the choices a chat does offer, such as the model.
Oda opens in English for everyone: it does not follow the language of your computer, and English is the only language it offers today.
No. Oda does not read your browser's languages: its interface is set to English, whatever the browser is set to.
It does not pick one: Oda opens in English and stays in English while it runs, and neither your computer nor your browser changes that.
A saved language that Oda does not offer is ignored: Oda runs in English, and the saved value changes nothing in the app.
Adding a language is plugin work: a language pack registers the language and its text with Oda. See Language packs for how a pack is added and the rules it follows.
