🌍 AI WhatsApp Translator – Multilingual Voice & Text Translator for n8n

Hi! I'm Bruno — I’ve been building AI-powered workflows for n8n and Make for 2+ years, focused on smart automation and real conversational agents.

This powerful workflow allows you to receive WhatsApp messages (text or audio), automatically detect the sender’s language using their phone prefix, translate the content using GPT-4o via LangChain, and reply instantly via WhatsApp — all with native tone and cultural fluency.

It’s ideal for international support, global communities, multilingual bots, and agencies managing clients from different countries.
