📝 A note on right-to-left languages (Arabic, Hebrew, Farsi, Urdu)

Our agents respond fluently in RTL languages out of the box. For the full experience — where the chat interface itself flips to right-to-left layout — a small UI configuration is required. This is available as an add-on and typically takes less than a day to implement.

What works, and how

Not all language capabilities are equal. Here's the honest breakdown.
