Generate Multi-Platform Social Media Posts with GPT-4.1 and PostPulse

Description

This workflow allows you to turn any idea for a post into platform-specific content using AI. You simply provide the concept, topic, or description of a post, and the AI generates drafts adapted to multiple social media platforms — LinkedIn, Telegram, TikTok, YouTube, X/Twitter, Instagram, Bluesky and Threads. Posts are created in PostPulse ready for review, scheduling, or publishing.

Make sure community nodes are enabled in your n8n instance before importing and using this template. 👉 To install it: Go to Settings → Community Nodes → Install and enter:"@postpulse/n8n-nodes-postpulse". 💡 For more details, see n8n Integration Guide: PostPulse Developers – n8n Integration
