"Most people open up Claude, enter a prompt, it spits something out, and they're like, 'I don't like this.' Well, you're not scraping top-performing YouTube videos, analyzing your own account for brand voice, and feeding all that into the model." That is the core insight from this episode of The Startup Ideas Podcast. The guest, Mr. Vibe Marketing, walks through his complete n8n workflow for creating social media content that actually performs — not by guessing, but by feeding AI a rich dataset of what is already working.

The episode is a detailed, step-by-step walkthrough of an end-to-end automation that scrapes YouTube and X for high-engagement content on a given topic, uses that data to generate fresh content ideas, researches those ideas for real stats and case studies, drafts a LinkedIn post using Claude, creates an image, and then sends the draft to Slack for a human review before optionally auto-publishing. The guest also gives away the entire workflow as a free template.
