📄 What this workflow does

This workflow automatically turns a topic and a reference image URL into a finished, branded article image. It uses GPT-4o to generate a short, detailed image prompt, sends it to FAL Flux image-to-image for rendering, polls until the job is completed, downloads and resizes the image, overlays your company logo, and finally saves the branded result into a specified Google Drive folder.

👤 Who is this for

Content teams who need consistent, on-brand article images. Marketing teams looking to scale blog and landing page visuals. Designers who want to automate repetitive resizing and branding tasks. Anyone who needs a pipeline from topic → AI illustration → Google Drive asset.

✅ Requirements

OpenAI (GPT-4o) API credentials (for image prompt generation). FAL API key for Flux image-to-image generation. Google Drive OAuth2 connection + target folder ID for saving images. A company logo file/URL (direct download link from Google Drive or any public URL).

⚙️ How to set up

Connect OpenAI GPT-4o in the “Create prompt” node. Add your FAL API key to all HTTP Request nodes (generate image, check image finish, Get image link). Replace the logo link in “Get company’s logo” with your own logo URL. Configure the Google Drive node with your OAuth2 credentials and set the correct Folder ID. Update the image_url in “Link image” (or pass from upstream data). Test the workflow end-to-end with a sample subject and image.

🔁 How it works

Form/Manual Trigger → Input subject + reference image URL. GPT-4o → Generates a <70-word sharp/detailed prompt (no text/logos). FAL Flux (HTTP Request) → Submits job for image-to-image generation. Polling Loop → Wait + check status until COMPLETED. Download Image → Retrieves generated image link. Resize Image → Standardize to 800×500 pixels. Get & Resize Logo → Fetch company logo, resize for branding. Composite → Overlay logo onto article image. Save to Google Drive → Final branded image saved in target folder.

8064-generate-branded-article-images-with-gpt-4o-fal-flux-and-google-drive

This n8n workflow automates the creation of branded images for articles using AI and stores them in Google Drive. It leverages OpenAI's capabilities to generate image prompts, then uses an external image generation service (likely Fal.ai or Flux.ai, inferred from the directory name) via an HTTP Request, and finally uploads the processed image to Google Drive.

What it does

This workflow streamlines the process of generating and storing branded article images:

  1. Manual Trigger: The workflow is initiated manually, allowing for on-demand image generation.
  2. Edit Fields (Set): Sets initial data, which likely includes the article title or content that will be used for image generation.
  3. OpenAI - Generate Image Prompt: Utilizes OpenAI (likely GPT-4o, inferred from the directory name) to generate a descriptive prompt suitable for image generation based on the provided article details.
  4. Wait: Introduces a pause in the workflow, potentially to allow for rate limiting or to ensure previous steps are fully completed before proceeding.
  5. HTTP Request - Generate Image: Sends the AI-generated prompt to an external image generation API (e.g., Fal.ai or Flux.ai) to create the actual image.
  6. If - Check Image Generation Status: Checks the response from the image generation API to determine if the image was successfully created.
  7. Edit Image - Add Branding (if successful): If image generation was successful, this node processes the generated image, likely adding branding elements (e.g., logo, text overlay) to it.
  8. Google Drive - Upload Branded Image: Uploads the final branded image to a specified folder in Google Drive.
  9. Merge: This node likely merges the output of the "If" node's true and false branches, or combines data from different parts of the workflow. (Its exact function depends on the configuration, which is not detailed in the JSON).
  10. Code - Handle Errors/Cleanup (if failed or after upload): This node would typically contain custom JavaScript logic to handle errors if image generation failed, or perform post-upload cleanup/logging.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • OpenAI API Key: For the OpenAI node to generate image prompts.
  • External Image Generation Service API Key: An API key for the external image generation service (e.g., Fal.ai, Flux.ai, or a similar service) used by the HTTP Request node.
  • Google Drive Account: With appropriate permissions to upload files to a designated folder.
  • Google Drive Credential in n8n: Configured to connect to your Google Drive account.

Setup/Usage

  1. Import the workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Set up your OpenAI API Key credential in n8n.
    • Configure the Google Drive credential with access to your desired Google Drive folder.
    • The HTTP Request node will require configuration for the external image generation service, including its API endpoint and authentication (likely an API key or token in the headers).
  3. Customize Nodes:
    • Edit Fields (Set): Adjust the input data (e.g., article title, keywords) that will be sent to OpenAI.
    • OpenAI: Review and adjust the prompt generation parameters if needed.
    • HTTP Request: Ensure the URL, method, headers (for authentication), and body (for sending the image prompt) are correctly configured for your chosen image generation service.
    • Edit Image: Customize the image editing operations, such as adding specific text, logos, or resizing.
    • Google Drive: Specify the target folder ID and file naming conventions for the uploaded images.
    • Wait: Adjust the wait duration if necessary.
    • Code: Customize the JavaScript code for error handling, logging, or any other custom logic.
  4. Activate the workflow: Once configured, activate the workflow.
  5. Execute: Click "Execute workflow" on the "Manual Trigger" node to run the workflow.

🎓 How to transform unstructured email data into structured format with AI agent

This workflow automates the process of extracting structured, usable information from unstructured email messages across multiple platforms. It connects directly to Gmail, Outlook, and IMAP accounts, retrieves incoming emails, and sends their content to an AI-powered parsing agent built on OpenAI GPT models. The AI agent analyzes each email, identifies relevant details, and returns a clean JSON structure containing key fields: From – sender’s email address To – recipient’s email address Subject – email subject line Summary – short AI-generated summary of the email body The extracted information is then automatically inserted into an n8n Data Table, creating a structured database of email metadata and summaries ready for indexing, reporting, or integration with other tools. --- Key Benefits ✅ Full Automation: Eliminates manual reading and data entry from incoming emails. ✅ Multi-Source Integration: Handles data from different email providers seamlessly. ✅ AI-Driven Accuracy: Uses advanced language models to interpret complex or unformatted content. ✅ Structured Storage: Creates a standardized, query-ready dataset from previously unstructured text. ✅ Time Efficiency: Processes emails in real time, improving productivity and response speed. *✅ Scalability: Easily extendable to handle additional sources or extract more data fields. --- How it works This workflow automates the transformation of unstructured email data into a structured, queryable format. It operates through a series of connected steps: Email Triggering: The workflow is initiated by one of three different email triggers (Gmail, Microsoft Outlook, or a generic IMAP account), which constantly monitor for new incoming emails. AI-Powered Parsing & Structuring: When a new email is detected, its raw, unstructured content is passed to a central "Parsing Agent." This agent uses a specified OpenAI language model to intelligently analyze the email text. Data Extraction & Standardization: Following a predefined system prompt, the AI agent extracts key information from the email, such as the sender, recipient, subject, and a generated summary. It then forces the output into a strict JSON structure using a "Structured Output Parser" node, ensuring data consistency. Data Storage: Finally, the clean, structured data (the from, to, subject, and summarize fields) is inserted as a new row into a specified n8n Data Table, creating a searchable and reportable database of email information. --- Set up steps To implement this workflow, follow these configuration steps: Prepare the Data Table: Create a new Data Table within n8n. Define the columns with the following names and string type: From, To, Subject, and Summary. Configure Email Credentials: Set up the credential connections for the email services you wish to use (Gmail OAuth2, Microsoft Outlook OAuth2, and/or IMAP). Ensure the accounts have the necessary permissions to read emails. Configure AI Model Credentials: Set up the OpenAI API credential with a valid API key. The workflow is configured to use the model, but this can be changed in the respective nodes if needed. Connect the Nodes: The workflow canvas is already correctly wired. Visually confirm that the email triggers are connected to the "Parsing Agent," which is connected to the "Insert row" (Data Table) node. Also, ensure the "OpenAI Chat Model" and "Structured Output Parser" are connected to the "Parsing Agent" as its AI model and output parser, respectively. Activate the Workflow: Save the workflow and toggle the "Active" switch to ON. The triggers will begin polling for new emails according to their schedule (e.g., every minute), and the automation will start processing incoming messages. --- Need help customizing?
