Generate Twitter/X Captions from Google Drive Images using Cloudinary & GPT-4o-mini

This n8n workflow transforms images in a Google Drive folder into engaging Twitter/X content. It triggers on new or updated images, downloads them, uploads to Cloudinary for a public URL, and leverages Azure OpenAI's GPT-4o-mini via LangChain to analyze visuals and create optimized captions including punchy headlines, 3-part tweet threads (hook-insight-action), alt text, hashtags, mentions, and posting times.

Benefits include massive time savings for social media managers and creators, ensuring high-quality, on-brand posts without manual effort. The output is delivered via a professional HTML email with the image, all content blocks, and summaries, ready for quick publishing.

Ideal use cases: Automate content for client accounts, turn visuals into postable threads instantly, or streamline marketing workflows. Perfect for teams handling high-volume image-based social media.
