🚀 AI-Powered LinkedIn Post Automation

🧩 How It Works

This workflow automatically generates LinkedIn posts based on a user-submitted topic, including both content creation and image generation , then publishes the post to LinkedIn. Ideal for marketers, content creators, or businesses looking to streamline their social media activity, without the need for manual post creation.

1. Trigger : The workflow is triggered when a user submits a form with a topic for the LinkedIn post.
2. Data Mapping : The topic is mapped and prepared for the AI ​​model.
3. AI Content Generation : Calls the Google Gemini AI model to generate engaging post content and a visual image prompt.
4. Image Creation : Sends the image prompt to the external API, gen-imager , to generate a professional image matching the topic.
5. Post Creation : Publishes the text and image to LinkedIn, automatically updating the user's feed.
