Auto-Post YouTube Shorts from Google Drive with OpenRouter AI Titles & Descriptions

How it works

This workflow automatically uploads YouTube Shorts from a Google Drive folder.
It picks one video at each run, generates a YouTube-optimized title, description, and hashtags using an AI model, uploads the video through YouTube’s resumable upload API, and finally moves the processed video to a “Posted” folder.
