LinkedIn Post Automation with Idea Filtering

somdn_product_page

This workflow is designed to automate the creation, refinement, and publication of LinkedIn posts centered around AI, product management, and startup topics. It starts with a scheduled trigger that initiates the process every day at 10 AM, setting the stage for idea generation based on a detailed brief targeting product managers, founders, AI enthusiasts, and startup hackers worldwide, including India. The workflow then employs AI models (GPT-5) to generate multiple potential post ideas, which are then ranked and filtered by relevance, creativity, and novelty, including deduplication against previous ideas stored in Google Sheets.

Subsequently, the selected idea is expanded into a short, engaging LinkedIn post draft with a compelling hook, core insights, and call-to-action, all refined for clarity and impactful delivery. The process includes specific content polishing steps to add factual details, improve tone, and ensure the post adheres to LinkedIn’s character constraints. The final post is then styled visually with an image generated via AI, with all content assembled into a structured package for publishing. This workflow is practical for personal branding, thought leadership, and content marketing in tech and startup ecosystems, ensuring fresh, relevant, and high-quality posts are consistently created and managed.

Key nodes include Schedule Trigger, AI-based idea generation and ranking, sophisticated content refinement nodes, image generation, and Google Sheets integration for logging and managing post ideas. The automation offers a scalable solution for busy content creators who want to remain active, relevant, and engaging across professional social platforms.
