Who’s it for

Content marketers, SEO teams, and founders who need fast, research-grounded blog posts or long-form articles—multi-language included. Works well for teams that want citations, outlines, and section-by-section drafting with minimal manual effort.

How it works / What it does

The workflow refines keywords, finds recent articles and authoritative citations, then synthesizes a master outline and loops through each section: generate search queries → fetch web results → summarize findings → write the section with the advanced model.

Finally, it aggregates all sections into a clean Markdown article. Optional delivery nodes (Email, Telegram) and an AI Agent are included but disabled by default.

How to set up

  1. Import the workflow JSON into n8n.
  2. Add your OpenAI credential
  3. Set simple_model / advanced_model in LLM Params

Requirements

  • n8n instance with outbound internet access.
  • OpenAI API access (Responses API + web_search_preview).
  • (Optional) Email/Telegram credentials if you want to deliver results async

How to customize the workflow

  • Edit prompts in LLM Params and Section Prompts to match tone, structure, and SEO style
  • Tweak recency and source rules in Search Articles / Search Citations.
  • Insert a human review step before “Write Section”, enable delivery nodes
  • Change working/output languages in the Language node

Research-Based Article Generator with OpenAI and Web Search for High SEO Scores

This n8n workflow automates the generation of research-based articles, leveraging AI and web search capabilities to produce content optimized for high SEO scores. It's designed to streamline content creation, from initial topic input to final article output, including options for human review and notification.

What it does

This workflow orchestrates a series of steps to generate comprehensive articles:

  1. Receives Article Request: It starts by accepting an article request via an n8n form, which typically includes the desired article topic.
  2. Initial Data Transformation: It processes the incoming data, setting up the necessary fields for the AI agent.
  3. AI Agent Article Generation: An AI Agent (likely powered by OpenAI and integrated with web search tools) is invoked to research the topic and generate the article content. This agent is configured to produce SEO-friendly content.
  4. Loop for Content Processing: The generated content is then processed in batches, allowing for structured handling of different article sections or data points.
  5. Splits Out Content Sections: It splits the content into individual sections or items for further processing.
  6. Converts to Markdown: The article content is formatted into Markdown, a lightweight markup language for creating formatted text.
  7. Aggregates Content: All processed content sections are then aggregated back into a single, cohesive article.
  8. Human-in-the-Loop Review (Optional):
    • Sends Telegram Notification: It can send a notification to a Telegram channel, potentially for a human to review the generated article.
    • Sends Email Notification: Alternatively, or in addition, it can send an email with the generated article for review.
  9. Final Output: The workflow concludes with the generated article, ready for publication or further action.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • OpenAI API Key: For the AI Agent to generate content.
  • Web Search API (Implicit): The AI Agent likely uses a web search tool (e.g., Google Search API) for research. This would require appropriate credentials for the chosen search provider.
  • Telegram Account/Bot (Optional): If you wish to receive notifications via Telegram, you'll need a Telegram bot and chat ID.
  • SMTP Server Credentials (Optional): If you wish to receive email notifications, you'll need an SMTP server configured for sending emails.

Setup/Usage

  1. Import the workflow: Download the JSON file and import it into your n8n instance.
  2. Configure Credentials:
    • AI Agent (Node 1119): Configure your OpenAI API key and any necessary web search API credentials.
    • Telegram (Node 49): If using Telegram for notifications, set up your Telegram Bot API Token and Chat ID.
    • Send Email (Node 11): If using email for notifications, configure your SMTP credentials.
  3. Configure the Form Trigger (Node 1225):
    • Activate the "n8n Form Trigger" node. This will generate a unique webhook URL.
    • Share this URL or embed the form to accept article topic submissions.
  4. Customize Content Generation (Node 1119 - AI Agent): Adjust the prompts and parameters within the AI Agent node to fine-tune the article generation process, focusing on desired tone, length, and SEO requirements.
  5. Activate the Workflow: Once all configurations are complete, activate the workflow.

Now, whenever the n8n form is submitted with an article topic, the workflow will automatically generate a research-based article, format it, and send it for review.

Automate Reddit brand monitoring & responses with GPT-4o-mini, Sheets & Slack

How it Works This workflow automates intelligent Reddit marketing by monitoring brand mentions, analyzing sentiment with AI, and engaging authentically with communities. Every 24 hours, the system searches Reddit for posts containing your configured brand keywords across all subreddits, finding up to 50 of the newest mentions to analyze. Each discovered post is sent to OpenAI's GPT-4o-mini model for comprehensive analysis. The AI evaluates sentiment (positive/neutral/negative), assigns an engagement score (0-100), determines relevance to your brand, and generates contextual, helpful responses that add genuine value to the conversation. It also classifies the response type (educational/supportive/promotional) and provides reasoning for whether engagement is appropriate. The workflow intelligently filters posts using a multi-criteria system: only posts that are relevant to your brand, score above 60 in engagement quality, and warrant a response type other than "pass" proceed to engagement. This prevents spam and ensures every interaction is meaningful. Selected posts are processed one at a time through a loop to respect Reddit's rate limits. For each worthy post, the AI-generated comment is posted, and complete interaction data is logged to Google Sheets including timestamp, post details, sentiment, engagement scores, and success status. This creates a permanent audit trail and analytics database. At the end of each run, the workflow aggregates all data into a comprehensive daily summary report with total posts analyzed, comments posted, engagement rate, sentiment breakdown, and the top 5 engagement opportunities ranked by score. This report is automatically sent to Slack with formatted metrics, giving your team instant visibility into your Reddit marketing performance. --- Who is this for?
