Ads Creator — Black Forest Labs Hackathon (n8n workflow) 🚀🎨

A lightweight n8n workflow built for the Black Forest Labs hackathon that turns calendar events into ready-to-use social media ads, short videos, and SEO keyword suggestions for maximum reach. ✨

This project demonstrates an automated pipeline that:

• 📅 reads events from a calendar
• ✍️ generates ad copy and SEO keywords using an LLM
• 🖼️ produces image-based ads and short video clips using Flux Kontext model
• 📧 finalizes the report and sends it as an email

Examples of generated ads are available in examples/generated_ads/.

Use case 🌟
