Create AI-Generated Books with GPT-4.1-mini, DALL-E, Google Drive and AWS S3

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:
Trigger: Workflow starts when a chat message is received.
Book Brief Agent: Generates the initial book concept (title, subtitle, and outline).
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.
Generate Cover Image: AI generates a custom book cover image.
Upload to AWS S3: Stores the cover image securely.
Configure Metadata: Adds metadata for title, author, and description.
Build Book HTML: Converts markdown-based content into HTML format.
Upload to Google Drive: Saves the HTML content for processing.
Convert to PDF: Transforms the book into a professional PDF.
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 Import the workflow into n8n.
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).
Add your API keys and credentials in n8n credentials manager.
Test the workflow by sending a sample chat message (e.g., “Write a book about AI in education”).
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.
