Generate and Auto-Publish LinkedIn Posts with GPT-4 Text and AI Images

Description

How it works
This workflow automates LinkedIn posting for businesses and personal brands.
It starts with a form where you submit your post idea. Then:
Message Model (OpenAI) generates the LinkedIn post text in a professional and engaging style.
Image Generation (OpenAI) creates a custom visual to match the post idea and brand style.
LinkedIn Node publishes the text + image directly to your LinkedIn account.

This way, you can go from idea → AI-written post → branded visual → live LinkedIn content, all in one automated flow.

Setup steps
Connect your Form Trigger (or replace with Google Forms/Typeform/Notion etc. if you prefer).
Configure OpenAI credentials for text and image generation.
Adjust the AI prompts with your own details: [business name], [founder name], [brand colors], [tone of voice].
Connect your LinkedIn account in the final node.

Requirements
OpenAI API key (for text + image generation)
LinkedIn account with API access
n8n instance (self-hosted or cloud)
