Where Oshiwambo is deployed

Oshiwambo supports the Bank of Namibia, the Communications Regulatory Authority of Namibia and national citizen support, hosted in-country under Namibia's sovereign AI programme.

WebchatWhatsAppTelegramSMSVoice / IVREmail
Namibia deployment

Citizens file complaints against banking, insurance, non-bank and telecom providers to any of four participating regulators through webchat and WhatsApp, without needing to know which regulator holds the mandate — supporting Oshiwambo, starting with the Oshikwanyama dialect, alongside Afrikaans, English and German.
