This template blends the power of AI with the crucial oversight of human expertise and intervention, all managed through a central, streamlined Airtable interface. Say goodbye to generic content and hello to high-quality, deeply researched articles published directly to your WordPress site with full control. 

What problem is this workflow solving? / Use cases

Fully automated content generation tools often lack the nuance, accuracy, and strategic control necessary for truly impactful content. This workflow solves that critical gap by integrating powerful AI capabilities into a structured, human-supervised content creation process managed via a simple interface. It automates the most repetitive and time-consuming tasks – like research gathering, chapter ideations, domain copywriting – while strategically embedding essential human review points at critical junctures.

Instead of simply providing a topic and receiving a finished article of uncertain quality, you actively guide the process step-by-step within an interface. You review, refine, and approve AI suggestions for chapters and content before finalizing and publishing. This approach makes it perfect for creating high-quality, deeply researched, and brand-aligned blog posts for WordPress more efficiently, without ever sacrificing essential editorial control.

Who is this for?

This workflow template is meticulously designed for individuals and teams deeply involved in content creation who seek a powerful blend of AI-driven efficiency and essential human-controlled quality assurance:

• Content Creators & Bloggers: Who want to leverage AI for drafting and research but maintain full editorial control.
• Marketing Teams: Looking to scale content production efficiently while ensuring brand voice and quality consistency.
• SEO Specialists: Needing to produce well-researched, structured, and SEO-optimized content regularly.
• Agencies: Managing content creation for multiple clients with a structured, repeatable process.
• Anyone who prefers a “human-in-the-loop” approach over fully automated “black box” content generators.

How this workflow works

This template automates significant portions of the WordPress content creation process, utilizing Airtable as the central hub for management and user interaction, while leveraging AI for research and copywriting. The system is composed of four interconnected n8n flows, each handling a distinct stage of the content lifecycle. In addition, there is a sub-workflow dedicated to the research tool (Perplexity).

Content Creation Process in Airtable

The entire journey from idea to published post is managed within your Airtable base, offering transparency and control. Progress through each tab sequentially to complete the content creation process and produce a high-quality article that fulfills your requirements.

1. Configure Settings (“Settings” Table): Define global parameters (website details, target audience, writing style, category IDs, about us, CTA etc.) in the “Settings” table. These serve as default inputs for the AI.
2. Create Topics (“Create Topics“ Table): Add a record to the “Create Topics” table for each new blog post idea. Mark the topic as ready by setting its ‘Status’ field to “To Do” and ticking the ‘Execute Flow’ checkbox to initiate the first flow.
3. Generate Chapters (“Generate Chapters“ Table): The first flow calls to the sub-workflow to do online research and generates potential chapter outlines based on your topic and settings, saving them to the “Generate Chapters” table.
4. Select Chapters to Write (“Select Chapters“ Table): Review the suggested chapters in the “Select Chapters“ Table. Select the chapters you want to proceed with by setting their ‘Status’ to “To Do” and ticking the ‘Execute Flow’ checkbox. 
5. Generate Content for selected Chapters (“Generate Content“ Table): The second flow calls to the sub-workflow to research each selected chapter and generates draft content, saving it to the “Generate Content” table, where you have the opportunity to review and modify if necessary.
6. Select Chapter Content (“Select Content“ Table): Review and edit the AI-generated text directly in Airtable. Approve the content for each chapter. Once all necessary content is approved, trigger the third flow for the final assembly by setting the status to “To Do” and ticking the ‘Execute Flow’ checkbox.
7. Finalize Post (“Finalize Post “Table): The third flow aggregates the approved content, generates the title, SEO metadata, tags, chapter images and featured image, placing all compiled information in the “Finalize Post” table for your final review. When the final article is ready to be published on your website, mark the status as “To Do” and check the “Ready to Publish” box to activate the fourth and final flow.
8. Publish & Backup Post (“Backup Post“ Table): the fourth flow publishes the post to the website and creates a backup record in the “Backup Post” table, archiving key details including the live URL of the published article.

n8n Workflow Functions (JSON Files)

The automation is handled by four separate n8n flows, each triggered by specific changes in Airtable:

1. Flow 1 (Topic Initiation & Chapter Generation):

• Trigger: Monitors the “Create Topics” table; activates when a record’s ‘Status’ is “To Do” AND ‘Execute Flow’ checkbox is ticked.
• Action: Fetches settings from Settings. Performs initial research (e.g., via Perplexity). Uses AI to generate chapter outlines. Saves suggestions as new records in the “Generate Chapters” table.

2. Flow 2 (Content Generation & Internal Linking):

• Trigger: Monitors the “Select Chapters” table; activates when a record’s ‘Status’ is “To Do” AND ‘Execute Flow’  checkbox is ticked.
• Action: Fetches chapter details and settings. Gathers internal links (e.g., by parsing sitemap). Performs online/ deep research per chapter. Uses AI to write draft content, incorporating research and links. Saves drafts into corresponding records in the “Generate Content” table.

3. Flow 3 (Post Assembly & Image Generation):

• Trigger: Monitors the “Select Content” table; activates when all content for a topic is approved and final assembly is triggered when a record’s ‘Status’ is “To Do” AND ‘Execute Flow’ checkbox is ticked.
• Action: Fetches all content from the “Generate Content” table. Aggregates text. Uses AI for title, SEO metadata, tags, and image prompts. Generates chapter images and a featured cover image (e.g., via AI image model DALL-E). Converts content to HTML. Saves compiled data and image info into the “Finalize Post” table.

4. Flow 4 (WordPress Publishing & Backup):

• Trigger: Monitors the “Finalize Post” table; activates when a record is marked Status’ is “To Do” AND ‘Post to Website’ checkbox is ticked.
• Action: Fetches finalized data. Uploads images to WordPress. Creates WordPress post (status set to “published” by default) with content, metadata, tags, and image. Creates a record in the “Backup Post” table, with a link to the post on the website.

This modular approach ensures each stage is handled distinctly, orchestrated via updates on Airtable interface.

8. Test Connections: Run manual executions on key nodes within each flow to ensure connections and basic configurations are correct before activating.
9. Activate Workflow: Toggle the “Active” switch ON for the main/ “mother” workflow in your n8n list. No need to activate the sub/ “child” workflow.
10. Test Run: Go to the Create Topics table in Airtable, add a new topic, go through the process and get amazed by AI magic!

Airtable Database Explanation

Airtable is the central hub, acting as the database, user interface, and trigger mechanism for this workflow.

• Structure: The base uses linked tables to manage the process:
  • Settings: Global configurations.
  • Create Topics: Initiates new content pieces.
  • Generate Chapters: Stores AI-generated chapter outlines for review.
  • Select Chapters: Facilitates user selection of chapters to write.
  • Generate Content: Stores AI-generated draft content for selected chapters.
  • Select Content: Manages user approval of drafted content before final assembly.
  • Finalize Post: Holds the compiled post (text, metadata, image info) for final review and publish trigger.
  • Backup Post: Archives data (including live URL) of successfully published posts.
• Workflow Interaction:
  • User updates trigger fields in Airtable (e.g., sets Status=’To Do’ & Execute Flow=true).
  • n8n Airtable Trigger nodes detect these specific changes.
  • The corresponding n8n flow runs, fetching data from Airtable.
  • AI and other tools process data and generate outputs.
  • Results are written back to the appropriate Airtable tables/fields.
  • User reviews results in Airtable and triggers the next stage via status AND checkbox updates.

• Setup: Using the exact duplicated Airtable base template is mandatory, as n8n workflows expect specific table and field names.

Tips for Pros

• AI Prompts: Modify prompts in the AI nodes to refine tone, style, format, or incorporate specific instructions.
• AI Models: the workflow is optimized for OpenAI’s GPT-4o model due to its consistent performance. While you can replace the AI models in the nodes with alternatives (if you have the credentials for them), keep in mind that the workflow may not function. 
• AI Research Model: PerplexityAI is the tool of choice for research. The “sonar” model is the default for research in this workflow due to its speed and cost-effectiveness. However, you are welcome to explore Perplexity’s other models, such as the “sonar-deep-research” model, which is specifically designed for in-depth research.
• AI Image Model: The default AI model for image generation is OpenAI’s Dall-E. However, the outputs of this model are not impressive. While OpenAI’s 4o multimodal is expected to be available via API soon, better/ superior image quality can be achieved in the meantime by using alternative AI image models (such as FLUX.1).
• Airtable Base: Add or modify fields/tables to match your specific tracking needs, but remember to update corresponding n8n nodes accordingly.
• Triggers: Change from Airtable update triggers to Schedule triggers for batch processing if preferred.
• 3rd-party Integrations: Replace research tools, image generators, or modify the final step to publish to a different CMS or add post-publication steps like social sharing.
• Error Handling: For production reliability, incorporate an “Error Handling” workflow in n8n for this automation to catch failures and send notifications

Important Considerations

• API Rate Limits: AI and research tools have usage limits. High volume processing might cause errors. The included Wait nodes help, but may need adjustment based on your API plans. 
• Sequential Processing: The workflow processes one topic fully at a time to ensure stability and manage API limits. For fully automated, parallel processing from a list, consider the alternative template: “[n8n] Content Automation Pro – with DEEP RESEARCH – WordPress Blog Automation”.
• Testing Costs: API calls to AI models aren’t free. To ensure the workflow runs correctly, start testing with OpenAI’s GPT-4o. Once you’ve confirmed functionality, explore using other AI models which may be cheaper to keep costs down. Be aware that the workflow may not be as reliable with models other than GPT-4o. Keep an eye on your API provider’s billing dashboard to monitor usage and costs.
