AI-Powered Brand Translation & Localization Engine

This project is an advanced automation pipeline built for a major German eCommerce cosmetics brand, designed to solve a critical challenge: translating marketing copy that is not just accurate, but perfectly on-brand. It transforms a simple Airtable base into an intelligent, self-service localization hub.

For a global cosmetics brand, maintaining a consistent voice, tone, and style across multiple languages is essential but incredibly difficult. Standard machine translation tools like DeepL are fast and accurate for literal text, but they fail to capture the specific promotional tone for an ad, the casual feel of an Instagram post, or the unique nuances of the brand's voice. This often leads to generic, off-brand copy that requires hours of manual rework by local marketing teams.

This workflow, orchestrated entirely in n8n, creates a sophisticated "AI review council" that combines the strengths of different translation technologies to produce superior, brand-aligned copy.

The entire process is managed from a central Airtable base where the marketing team works.

The Request (in Airtable): A team member enters the source text into an Airtable record. They don't just select a target language; they provide crucial context by choosing the Tone (e.g., Promotional), Use Case (Ads), and Translation Style (Free).

Dynamic Guideline Injection: The automation instantly fetches a comprehensive set of brand guidelines stored in another Airtable table. This includes the core brand voice, market-specific rules (e.g., for the US vs. Netherlands), and instructions specific to the selected tone and use case.

The Dual-Engine Translation: The system sends the source text down two parallel paths simultaneously:

The AI Quality Reviewer: This is the system's most powerful feature. A final AI agent is activated, acting as a "Senior Translation Reviewer." It receives:

Its task is to critique both versions, combine their best elements, correct any flaws, and synthesize one final, superior translation. It also generates a detailed Explanation of the changes it made and why, referencing the brand guidelines.

Seamless Delivery to Airtable: The workflow updates the original Airtable record in real-time at every step. The final, polished translation and the AI's explanation are populated directly into the designated fields, and the status is marked as "Complete." The team gets a perfect, ready-to-use translation without ever leaving their workspace.

Superior Translation Quality: By combining DeepL's precision with Claude's contextual creativity and a final AI review, the system consistently outperforms any single tool.

Guaranteed Brand Consistency: The dynamic guideline system ensures every piece of copy, regardless of language, adheres strictly to the brand's voice and market-specific rules.

Massive Time & Cost Savings: Eliminates the slow, expensive back-and-forth between marketing teams and freelance translators for creative copy.

Empowers the Marketing Team: Provides a self-service tool that is easy to use and delivers results in minutes, dramatically increasing operational agility.

Built-in Quality Assurance: The AI-generated "Explanation" provides full transparency into the translation process, building trust and offering valuable insights.
