Localize Brand Voice with Groq Chat Completions in n8n

Localize your content in seconds—while keeping your brand voice consistent

This n8n workflow sends text to Groq’s OpenAI-compatible Chat Completions API to produce localized translations that preserve your tone and glossary terms, then returns a structured JSON response with quality checks. Perfect for reliable, repeatable multilingual localization in your automation pipeline.

What this workflow does

• Receives a POST request via an n8n webhook containing the source text/content plus optional localization settings: target_language, tone, and glossary.
• Builds a chat prompt instructing the model to translate into the requested language while preserving brand voice and using all glossary terms verbatim.
• Calls Groq Chat Completions using Groq’s OpenAI-compatible endpoint to generate the translation and related metadata.
• Parses and normalizes the model output, extracting the translation, glossary matches, tone check status, and localization notes.
• Returns only JSON to the original caller via “respond to webhook,” including the structured localization results.

Use cases

• Localize SaaS UI/help-center copy while enforcing consistent terminology via a shared glossary.
• Automate multilingual marketing translation with a defined friendly-professional tone.
• Quality-check translations by capturing tone check status and localization notes in your downstream workflow.
