I built an automated Instagram content workflow that generates AI video prompts, creates short-form Veo3 videos, writes engaging captions, and publishes posts directly to Instagram. Using n8n, Veo3, and Blotato, the system processes user input, generates a prompt with GPT, produces the video, waits for rendering, uploads media, and posts to Instagram while saving all data to Google Sheets. This workflow reduces manual workload, accelerates content production, and ensures consistent, high-quality posting for brands and creators.
