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

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.
