AI Content Summarizer Agent for WordPress Posts

Unlock Effortless Content Enhancement with this AI Agent

This n8n AI Agent automates the creation and insertion of AI-generated summary blocks directly into your WordPress posts. It leverages OpenAI's advanced language models (like GPT-4o-mini) to understand your article content and produce concise, well-formatted HTML summaries. This not only saves significant editorial time but also boosts reader engagement and can improve SEO by providing quick takeaways.

Key Abilities & Benefits

• AI-Powered Content Summarization: Utilizes OpenAI to generate high-quality, contextually relevant summaries for your WordPress articles.
• Automated WordPress Integration: Seamlessly fetches posts, intelligently checks if a summary is needed (via Google Sheets log and AI content analysis), and updates the post content with the new HTML summary block at the top.
• Smart Duplicate Prevention: Employs a two-tiered check: first against a Google Sheets log of processed posts, then uses an AI Text Classifier to detect existing summaries within the post content itself, ensuring posts are not processed redundantly.
• Flexible Triggers: Initiate summaries manually for testing, on a recurring schedule for ongoing content, or via a webhook for real-time processing of newly published posts.
• Customizable HTML Output: Generates summaries in a specific HTML block format, which can be styled to match your WordPress theme. The prompt includes guidance for HTML structure.
• Comprehensive Logging: Records details of each summarized post (ID, title, links, summary date) into a designated Google Sheet for easy tracking and auditing.
• Team Collaboration: Optionally sends notifications to a Slack channel, keeping your content or marketing team informed of updates.
• Lightweight Solution: Achieves this automation without requiring additional WordPress plugins, keeping your website performance optimal.

• An n8n instance (Cloud or self-hosted).
• OpenAI API Key with access to a suitable model (e.g., GPT-4o-mini is used in the template).
• WordPress site credentials configured in n8n (e.g., Application Password for REST API access).
• Google Cloud Service Account credentials for Google Sheets API access.
• A Google Sheet prepared for logging (you can make a copy of the provided template).
• Slack API credentials (OAuth2 recommended) and the ID of a target channel for notifications.

1. Download the n8n workflow JSON file.
2. Import the workflow into your n8n instance.
3. Configure Triggers: The workflow offers Manual, Schedule, and Webhook triggers. By default, the 'When clicking ‘Test workflow’' (Manual) trigger is connected. Review the 'Trigger - Two Options' sticky note in the workflow. Enable your preferred trigger and connect it to the subsequent 'WordPress - Get...' node, then disable or disconnect the other triggers.
4. WordPress Credentials & URL: a. Configure all 'WordPress' nodes with your WordPress API credentials. b. In the 'Wordpress - Update Post' (HTTP Request) node, update the URL placeholder https://<your-domain.com>/... with your actual WordPress domain. c. In the 'Set fields - Prepare data for Gsheets & Slack' node, update the edit_link expression https://<your-domain.com>/... with your domain.
5. OpenAI Credentials: In the 'OpenAI Chat Model' (used by Text Classifier) and 'OpenAI' (for summary generation) nodes, select or create your OpenAI API credential. Ensure the selected model (e.g., gpt-4o-mini) is appropriate for your needs and budget.
6. Google Sheets Setup: a. Make a copy of the Google Sheets template for logging summarized posts. b. Configure the 'Google Sheets - Get rows' and 'Google Sheets - Add Row' nodes: select your Google Sheets API credentials, then enter the Document ID (from your copied sheet's URL) and the correct Sheet Name (e.g., 'AI-Summarized Posts').
7. Slack Configuration: Configure the 'Slack - Notify Channel' node by selecting your Slack API credentials and specifying the target Channel ID for notifications.
8. Customize OpenAI Summary Prompt: Open the 'OpenAI' node (id 3272ff54-9c8f-4003-bdf6-c16e8f4ba972). Review and customize the system_prompt. Pay special attention to: a. The website's theme (e.g., change 'electric vehicles and green mobility' if needed). b. The 'Good' and 'Bad' output examples to match your content style. c. The HTML structure and styling (background color, fonts, title '✨ AI Summary') to align with your WordPress theme. Refer to the 'OpenAI - Message a Model' sticky note for guidance.
9. Review Node Settings: Check other nodes like 'WordPress - Get All Posts' for limits (defaulted to 5 for safety during testing) and adjust as needed for production.
10. Test Thoroughly: Run the workflow with the manual trigger on a few test posts. Verify the summary generation, WordPress update, Google Sheets logging, and Slack notification.
11. Activate the workflow with your chosen trigger for automated operation.
