LinkedIn Content Creator System

Overview

Automate your entire LinkedIn content machine — from research and image generation to scheduling and posting — with this AI-powered workflow.

This workflow pulls in past content ideas, researches new ones using Perplexity, generates a new post (with image) using your brand's voice and style, saves the output to Google Sheets, and auto-posts twice a week to LinkedIn. It’s perfect for founders, creators, and marketers who want to stay consistent on LinkedIn without manually writing or designing every post.
