Create Animated Stories with PiAPI n8n Workflow Using GPT-4o, Midjourney & Kling APIs

Imagine sketching out a scene where a rabbit by a forest stream, golden light breaking through the leaves and watching it come alive as a short animated video in just minutes. No cameras. No editing suites. Just prompts, a workflow and PiAPI’s AI models powering the visuals, sound, and storytelling.

That’s exactly what our n8n workflow template delivers. By combining GPT-4o image generation, Midjourney, Kling and Creatomate you can generate high-quality short videos that are perfect for social posts, vlogs, product demos or even classroom explainers.
