Formation n8n en Français : Automatisation & Agents IA
This course page lets you rebuild the workflow manually, node by node, live on camera. Every prompt, expression, JSON body and URL is in a copy-paste code block.
What the workflow does: it scans the Hacker News front page, one single OpenAI call picks the most exciting AI/automation story and writes a full video brief (cinematic prompt + title + caption + hashtags), AtlasCloud (Veo 3.1 Fast) generates a short vertical AI video with an automatic polling loop, and Blotato publishes the finished video to YouTube and TikTok, correctly flagged as AI-generated content.
