AI-Powered Children’s Illustrations & Story Generator with n8n and Replicate API

Introduction

Creating captivating children’s stories paired with vibrant illustrations has traditionally required significant time, artistic skill, and resources. However, advances in artificial intelligence are transforming this creative process, making it accessible to anyone with an idea. By leveraging AI-powered tools, authors and creators can now effortlessly generate both engaging narratives and matching illustrations in minutes.

In this article, we explore a custom-built workflow using n8n automation combined with replicate.com’s ideogram-ai/ideogram-v2a-turbo model. This system allows users to input a simple one-liner prompt—such as “2 tomatoes become friends in garden”—and automatically produces a short children’s story along with a colorful illustration that brings the tale to life. This seamless integration of AI storytelling and image generation opens new possibilities for educators, parents, and aspiring authors to create personalized children’s books quickly and creatively.

What are we going to build

Feel free to create an account in n8n and launch your instance, or self-host your n8n in your infrastructure

Step 1 - Input Form

Let's start by adding our trigger node, which is on form submission, with the following settings

When the workflow starts, users should see a form like the following

Step 2 - Generate Story

Next, add a new node using OpenAI message a model and use GPT-4.1-Nano as the model with the following prompts

System Prompt

User Prompt

Step 3 - Save the Story in Google Docs

Add a new node to create a folder in your Google Drive

The folder title will be the story title generated by the OpenAI model.

Now, let's add a new document to the Folder to write an AI-generated story.

Now let's loop (batch of 1) over each paragraph of the generated story and write it to the doc

Step 4 - Generate the Prompt for Image

From the Create Folder node, add a new branch to generate an Image generation prompt using the OpenAI model, providing the story and asking the model to write a prompt to generate a children's illustration for that story. Add a new OpenAI message to a model node using GPT-4.1-NANO model

System Prompt

User Prompt

Step 5 - Generate the Image with Replicate

Now let's make an HTTP call to the replicate.com endpoint and generate an image using ideogram-ai/ideogram-v2a-turbo The model feeding prompt was generated in the previous step. Here are the details of the HTTP node

• Method: POST
• URL: https://api.replicate.com/v1/models/ideogram-ai/ideogram-v2a-turbo/predictions
• Add a header for Authorization Bearer [your-replicate-api-key]
• Add a header for Content-Type application/json
• Add a header for Prefer wait

Check the Send Body flag and add the following as JSON to it

After this node, add another HTTP node to get the Binary file of the generated image, so we can use it to save in the Google Drive

Step 6 - Save the Image to Google Drive

Using the downloaded binary file to upload it to the Google Drive

Conclusion

By combining the power of AI-driven storytelling and illustration generation within an automated n8n workflow, creating personalized children’s books has become remarkably simple and efficient.
