Generate AI News LinkedIn Posts with GPT-4o Mini, NewsAPI, and Qdrant

This n8n workflow automates the process of generating engaging LinkedIn posts about AI news. It leverages the NewsAPI to fetch recent articles, uses an AI agent (GPT-4o Mini) to summarize and extract key information, stores relevant data in Qdrant for context, and then drafts LinkedIn posts. The workflow includes a human-in-the-loop approval step via Gmail before publishing.

What it does

  1. Triggers on a Schedule: The workflow runs on a predefined schedule (e.g., daily).
  2. Fetches AI News: Uses the NewsAPI to retrieve the latest articles related to "Artificial Intelligence".
  3. Filters and Prepares Data:
    • Filters out articles that might be irrelevant or lack sufficient content.
    • Prepares the article data for AI processing.
  4. Generates Embeddings: Creates vector embeddings of the fetched articles using OpenAI Embeddings.
  5. Stores in Vector Database: Stores the article embeddings and metadata in Qdrant for efficient retrieval and context.
  6. Retrieves Relevant Context: Queries Qdrant to find similar or related articles to provide context to the AI agent.
  7. AI Agent for Content Generation:
    • Utilizes an AI agent (GPT-4o Mini via OpenAI Chat Model) to analyze the news articles and generate a summary, key takeaways, and a draft LinkedIn post.
    • Employs a Structured Output Parser to ensure the AI output adheres to a defined format.
  8. Human-in-the-Loop Approval: Sends a draft of the LinkedIn post via Gmail for review and approval.
  9. Conditional Posting: If approved, the workflow proceeds to post to LinkedIn. (Note: The LinkedIn posting node is not present in the provided JSON, but the structure suggests this as the intended next step after approval).
  10. Updates Google Sheets: Logs the generated post details and status to a Google Sheet.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance.
  • NewsAPI Account: An API key for NewsAPI to fetch news articles.
  • OpenAI Account: An API key for OpenAI (for Embeddings and the Chat Model, specifically GPT-4o Mini).
  • Qdrant Instance: Access to a Qdrant vector database (either self-hosted or cloud-based).
  • Gmail Account: A Gmail account configured as a credential in n8n for sending approval emails.
  • Google Sheets Account: A Google Sheets account configured as a credential in n8n for logging data.
  • LinkedIn Account: (Implied) A LinkedIn account configured as a credential in n8n for publishing posts. (Note: The LinkedIn node is not in the JSON, but would be required for the full functionality described by the directory name).

Setup/Usage

  1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Set up credentials for NewsAPI, OpenAI, Qdrant, Gmail, and Google Sheets in your n8n instance.
    • Replace placeholder credentials with your actual API keys and access tokens.
  3. Adjust Node Settings:
    • Schedule Trigger (Node 839): Configure the desired schedule for the workflow to run (e.g., every day at a specific time).
    • HTTP Request (NewsAPI - Node 19): Ensure the NewsAPI endpoint and parameters are correctly set up, including your API key.
    • Embeddings OpenAI (Node 1141): Select your OpenAI credential.
    • Qdrant Vector Store (Node 1248): Configure your Qdrant instance details (host, API key, collection name).
    • OpenAI Chat Model (Node 1153): Select your OpenAI credential and ensure the model is set to gpt-4o-mini or similar.
    • Gmail (Node 356): Configure the recipient email address for approval requests.
    • Google Sheets (Node 18): Specify the Google Sheet ID and sheet name where the data should be logged.
  4. Activate the Workflow: Once all configurations are complete, activate the workflow.

The workflow will then automatically fetch news, generate content, send for approval, and (upon approval) post to LinkedIn and log the activity.

Two-way property repair management system with Google Sheets & Drive

This workflow automates the repair request process between tenants and building managers, keeping all updates organized in a single spreadsheet. It is composed of two coordinated workflows, as two separate triggers are required — one for new repair submissions and another for repair updates. A Unique Unit ID that corresponds to individual units is attributed to each request, and timestamps are used to coordinate repair updates with specific requests. General use cases include: Property managers who manage multiple buildings or units. Building owners looking to centralize tenant repair communication. Automation builders who want to learn multi-trigger workflow design in n8n. --- ⚙️ How It Works Workflow 1 – New Repair Requests Behind the Scenes: A tenant fills out a Google Form (“Repair Request Form”), which automatically adds a new row to a linked Google Sheet. Steps: Trigger: Google Sheets rowAdded – runs when a new form entry appears. Extract & Format: Collects all relevant form data (address, unit, urgency, contacts). Generate Unit ID: Creates a standardized identifier (e.g., BUILDING-UNIT) for tracking. Email Notification: Sends the building manager a formatted email summarizing the repair details and including a link to a Repair Update Form (which activates Workflow 2). --- Workflow 2 – Repair Updates Behind the Scenes:\ Triggered when the building manager submits a follow-up form (“Repair Update Form”). Steps: Lookup by UUID: Uses the Unit ID from Workflow 1 to find the existing row in the Google Sheet. Conditional Logic: If photos are uploaded: Saves each image to a Google Drive folder, renames files consistently, and adds URLs to the sheet. If no photos: Skips the upload step and processes textual updates only. Merge & Update: Combines new data with existing repair info in the same spreadsheet row — enabling a full repair history in one place. --- 🧩 Requirements Google Account (for Forms, Sheets, and Drive) Gmail/email node connected for sending notifications n8n credentials configured for Google API access --- ⚡ Setup Instructions (see more detail in workflow) Import both workflows into n8n, then copy one into a second workflow. Change manual trigger in workflow 2 to a n8n Form node. Connect Google credentials to all nodes. Update spreadsheet and folder IDs in the corresponding nodes. Customize email text, sender name, and form links for your organization. Test each workflow with a sample repair request and a repair update submission. --- 🛠️ Customization Ideas Add Slack or Telegram notifications for urgent repairs. Auto-create folders per building or unit for photo uploads. Generate monthly repair summaries using Google Sheets triggers. Add an AI node to create summaries/extract relevant repair data from repair request that include long submissions.
