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 call 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.
