Your note articles turned into 4-panel manga e-books. I created "4-koma no+e"

I have created an application called "4-koma no+e" that automatically generates e-books (EPUB) from your note articles, which you can then publish on platforms like Kindle.

It started with my own desire to turn my note articles into 4-panel manga, so I tried converting the articles I wrote last year. Since I'm using note, I figured others might want to do the same, so I built the "4-koma no+e" application based on the program I created at that time.

I feel that many of the articles written on note have very compelling content. However, I also felt that there were high hurdles to turning them into published works. Many creators want to focus on their creative work, so making publications often gets pushed to the back burner. Therefore, I developed this application to let a program handle the tedious tasks that tend to get postponed.


4-koma no+e

As for what kind of service it is, it literally uses AI to summarize your note articles and generate 4-panel manga images. Then, it compiles the created images into a single EPUB e-book. The works you create can be read on Kindle or Apple Books, and you can actually sell them on the Kindle Store. You can see what kind of things can be created by looking here.

You can add a full-body image of the character, and I will create a 4-panel image based on this illustration.

6. Set Gemini API Key

Create a Gemini API key🗝️

You can obtain an API key from Google AI Studio. Unfortunately, at this time, image generation is not available in the free tier. It is a pay-as-you-go system where you pay only for what you use, rather than a fixed monthly fee. For personal use, it is quite affordable, costing only a few to several dozen yen per episode.

7. Create reference 4-panel image

Set a reference image for creating a 4-panel manga

Create a sample, and if you get a 4-panel manga that looks good, save it as a reference image. Copying and pasting an article is also fine. It is a bit more difficult, but you can also create multiple characters and set them individually.

8. Scenario generation

Once you create a scenario, you will be able to generate images. If you create too many at once, you won't be able to redo them, so please start by testing with a small number of panels to see what kind of images are produced as you proceed.

You can check the 4-panel manga you created. You can edit the scenario and recreate it. You can also download it once and upload a corrected version. Please try to create a 4-panel manga you are satisfied with.

Although it involves manual work, I have summarized how to create 4-panel manga for free, so please give that a try as well.

Summary

I created "4koma no+e" to compile note articles into 4-panel manga e-books. Whether it is daily essays, travel logs, or stories about your fandom—what you have written on note is already material for a book.

Having your articles turned into 4-panel manga and listed on the Kindle Store is a simply exciting experience.
