Overview
Tired of cookie-cutter “AI LinkedIn post generators”? This workflow goes beyond just text generation — it orchestrates the entire lifecycle of a LinkedIn post. From idea capture to deduplication, from GPT-powered drafting to automatic image generation and link storage, it creates ready-to-publish posts while keeping your content unique and audit-friendly.
What does this workflow do?
This workflow:
Captures Ideas & Briefs – Inputs are logged in Google Sheets with audience, goals, and angles.
Deduplicates Smartly – Avoids repeating hooks or ideas with fuzzy GPT-based dedupe + GSheet logs.
Generates Posts – GPT (OpenAI) drafts sharp LinkedIn-ready posts based on your brief.
Creates Images – Post hook + body is sent to an Image Gen model (DALL·E / SDXL) → PNG asset.
Stores & Links – Final text + image uploaded to Google Drive with shareable links.
Audit Trail – GSheets keeps full history: raw idea, draft, final post, assets, notes.
Why is this useful?
Most “AI post generators” just spit out text. This workflow builds a real publishing pipeline:
🔄 No duplicates → keeps posts fresh & original.
🖼 Images included → auto-generated visuals increase engagement on LinkedIn.
📊 Audit-ready → every post has a traceable log in Sheets.
⚡ Fast iteration → from half-baked thought → polished post in minutes.
Tools used
n8n (Orchestrator): Automates triggers, merges, retries, and Google connectors.
OpenAI (LLM): Idea generation, drafting, fuzzy dedupe, and voice conformity.
Google Sheets: Source of truth — stores ideas, dedupe logs, audit trail.
Google Drive: Stores rendered images and shares links for publishing.
Image Generation (DALL·E / SDXL): Creates header graphics from hook + body.
Who is this for?
🧑💻 Product Managers / Founders who want to post consistently but don’t have time.
🎨 Creators who want to add unique visuals without hiring a designer.
⚙️ n8n Builders who want to see how AI + automation + storage can be stitched into one pipeline.
