The feature at Settings > Artificial Intelligence > Multilingual via translation automatically translates user messages into the default language of Dialogflow or OpenAI, and translates Dialogflow or OpenAI messages into the language spoken by the user. Additionally, this feature translates all text displayed within the chat, such as the chatbot's rich messages, registration forms, and pop-up notifications. To enhance performance and minimize translation costs, the translations are automatically integrated into the translation files. Combine this feature with the language detection feature for optimal results.
