Multi-Agent Book Creation Workflow with AI Tool Node and GPT-4, DALL-E

Watch the video

Who’s it for

This workflow is designed for:

  • Content creators who want to generate books or structured documents automatically.
  • Educators and trainers who need quick course materials, eBooks, or study guides.
  • Automation enthusiasts exploring multi-agent systems using the newly released AI Tool Node in n8n.
  • Developers looking for a reference template to understand orchestration of multiple AI agents with structured output.

How it works / What it does

This template demonstrates a multi-agent orchestration system powered by AI Tool Nodes:

  1. Trigger: Workflow starts when a chat message is received.
  2. Book Brief Agent: Generates the initial book concept (title, subtitle, and outline).
  3. Book Writer Agent: Expands the outline into full content by collaborating with two sub-agents:
    • Designer Agent → Provides layout/design suggestions.
    • Content Writer Agent → Drafts and refines chapters.
  4. Generate Cover Image: AI generates a custom book cover image.
  5. Upload to AWS S3: Stores the cover image securely.
  6. Configure Metadata: Adds metadata for title, author, and description.
  7. Build Book HTML: Converts markdown-based content into HTML format.
  8. Upload to Google Drive: Saves the HTML content for processing.
  9. Convert to PDF: Transforms the book into a professional PDF.
  10. Archive to Google Drive: Final version is archived for safe storage.

This workflow showcases multi-agent coordination, structured parsing, and seamless integration with cloud storage services.

How to set up

  1. Import the workflow into n8n.
  2. Configure the following connections:
    • OpenAI (for Book Brief, Book Writer, Designer, and Content Writer Agents).
    • AWS S3 (for image storage).
    • Google Drive (for document storage & archiving).
  3. Add your API keys and credentials in n8n credentials manager.
  4. Test the workflow by sending a sample chat message (e.g., “Write a book about AI in education”).
  5. Verify outputs in Google Drive (HTML + PDF) and AWS S3 (cover image).

Requirements

  • n8n (latest version with AI Tool Node support).
  • OpenAI API key (to power multi-agent models).
  • AWS account (with S3 bucket for storing images).
  • Google Drive integration (for document storage and archiving).
  • Basic familiarity with workflow setup in n8n.

How to customize the workflow

  • Switch Models: Replace gpt-4.1-mini with other models (faster, cheaper, or more powerful).
  • Add More Agents: Introduce agents for editing, fact-checking, or translation.
  • Change Output Format: Export to EPUB, DOCX, or Markdown instead of PDF.
  • Branding Options: Modify the cover generation prompt to include company logos or specific style.
  • Extend Storage: Add Dropbox, OneDrive, or Notion integration for additional archiving.
  • Trigger Alternatives: Replace chat trigger with form submission, webhook, or schedule-based runs.

✅ This workflow acts as a free, plug-and-play template to showcase how multi-agents + AI Tool Node can work together to automate complex content creation pipelines.
