Generate AI-Powered LinkedIn Posts with Ollama, Image Creation, and Gmail Delivery

This automation flow is designed to generate professional, research-backed LinkedIn posts based on a user-submitted topic and audience, enhance it with a visually aligned image prompt, and then automatically send the post and image via Gmail and/or publish it to LinkedIn.
⚙️ How It Works (Step-by-Step):

1. 📝 Form Submission (Input Trigger)

   A user fills out a form with:

    Email
   
    Topic of the Post
   
    Target Audience
   

   This form submission acts as the entry point of the workflow (Form Trigger node).

2. 🤖 LinkedIn Post Generation Agent

   An AI agent is triggered that:

    Uses Tavily API to fetch real-time web search content related to the topic.
   
    Processes the topic and audience data using an Ollama Chat Model.
    
   Generates a well-structured LinkedIn post that includes:
   
    Hook
   
    Educational insight
   
    Professional tone
   
    Source citations
   
    Hashtags and calls to action
   

3. 🎨 Image Prompt Agent

   The generated post is passed to a second agent that:

    Extracts the core message.
   
    Converts it into a graphic prompt using a different Ollama LLM.
   
    The prompt is written to be used by an image-generation model like DALL·E or Gemma/GPT-based image tools.
   

4. 🖼️ Image Generation

   The image prompt is passed to a local image generation endpoint (localhost:8098) or OpenAI ( api.openai.com ) to generate a visual asset.

   The base64 image is converted into a file.

5. 📩 Email Dispatch

   The post text and the generated image are then sent to the user's email address via the Gmail node.

   The email includes:

    The full LinkedIn post
   
    The auto-generated image as an attachment
   

6. 🔗 LinkedIn Publishing (Optional)

   If OAuth is enabled, the post can also be published directly to LinkedIn using the LinkedIn node.
