Route multilingual support requests with DeepL, GPT-3.5 and Gmail

Your automated multilingual support assistant that translates, generates AI responses, and translates back to the customer's language with comprehensive error handling.


Stop manually copy-pasting customer messages into Google Translate and crafting responses in multiple languages. This workflow orchestrates the entire multilingual support pipeline: captures requests via form, auto-detects and translates to English, generates professional AI responses, and translates back to the customer's native language automatically. You handle the business; it handles the languages.

This is not a generic "translation" template. It is a functional bidirectional communication pipeline designed to maintain conversation quality across 29 languages with production-grade error recovery.

How the workflow works

The workflow executes in five strategic stages:

1. Form Capture & Validation: Customer submits request via n8n form (email, question, language dropdown with 29 options). Validates email format, message length (5+ chars), and extracts ISO language code.
