Customers notice two things immediately: whether the agent speaks their language and whether it sounds like your business. This article covers both.
In the agent editor, under Configuration, the Language dropdown sets the single language the agent replies in. The hint in the editor explains why: one language per agent prevents language mixing and reduces hallucination.
Supported languages include Arabic, English, Spanish, French, Turkish, Urdu, Hindi, Chinese, Korean, Japanese, Portuguese, German, Italian, Russian, Indonesian, Malay, Filipino, Thai, Vietnamese, Persian, Dutch, Polish and Swahili.

Create two agents, for example "Reception (AR)" and "Reception (EN)":
Knowledge sources can be in either language. Add Canonical labels in both, such as Laser hair removal, ليزر, so an Arabic question finds an English document and the other way round.
There is no separate tone switch. Tone lives in the Instructions, which HueChat treats as the primary directive for behaviour. Be concrete:
Starter templates already include a tone line you can edit. If the agent ignores a rule, make it more specific and move it higher in the Instructions.
Two settings adjust tone automatically:
Under Voice Replies you can let the AI answer with a voice message when the customer sends one. Choose a voice from the Arabic set (Saudi male and female voices) or the English set, and a speed. Exact options may differ by plan.
The Language setting affects customer replies only. The HueChat dashboard itself is available in eight interface languages, with full right-to-left Arabic, chosen in your profile settings. Platform messages such as surveys follow the customer's language.
