A new video deserves more than one post on one network. This n8n workflow reads your YouTube channel feed, pulls the latest video and its thumbnail, writes a promo caption for each platform, and creates draft posts across all your connected accounts via Posta — so you review and publish instead of starting from a blank box.
What it does
- Reads your YouTube channel RSS feed and picks the newest video.
- Downloads the thumbnail and uploads it to Posta (auto-scaled per platform).
- Uses an LLM to write a promo caption per platform, created as drafts for review.
How it works
- HTTP Request — fetch the channel feed
https://www.youtube.com/feeds/videos.xml?channel_id=YOUR_CHANNEL_ID(HTTP, since n8n’s RSS node strips fields). - XML → Code — parse to JSON and build a structured object for the latest video.
- HTTP → Upload media (Posta) — download and upload the thumbnail.
- Get accounts → Filter → Remove Duplicates — one post per platform type.
- LLM (DeepSeek) — write a promo caption per platform.
- Create a post (Posta) — created as drafts so you can review before publishing.
