No API Key or technical knowledge required. Create unlimited covers for yourself or sell to others.

Before anyone reads a single word of your book, they've already made a judgment. A cover doesn't just attract attention... it communicates credibility, genre, and quality in under three seconds. Get it wrong, and the content inside never gets a chance.
Average time a reader spends deciding whether to click on a book

Reason self-published books are dismissed — an unprofessional cover
That's not shallow... it's how the brain processes trust and quality at a glance.
In a crowded market, whether you're selling on Amazon, promoting a lead magnet, or launching a course... your cover is your first sales tool.
It signals to a potential reader: this is worth your time. A weak cover signals the opposite, no matter how strong the content is.
Stops the scroll - In thumbnail-sized listings on Amazon, Gumroad, or social media, a well-composed cover stands out from the noise and earns the click.
Signals credibility instantly - Readers associate cover quality with content quality. A polished cover tells them you take your work seriously — before they read a word.
Attracts the right audience - Genre, mood, and tone are all communicated visually. The right cover pre-qualifies your reader — so the people who pick it up are already the ones most likely to love it.
Increases conversion at every touchpoint - Whether it appears in an email, a social post, or a product listing, a strong cover converts browsers into buyers more effectively than any description alone.
The good news: you don't need a design budget or years of creative experience to get a professional result. You just need the right starting point, and the right tools...
For years, AI image generators had one glaring weakness: they couldn't reliably render text. Titles came out blurry. Author names were garbled. Letters melted into decorative scribbles. That made them nearly useless for book covers... until now.
Two AI models came out recently that are both great at rendering text...
GPT Image 2.0 (gpt-image-2)
Nano Banana 2 (Gemini 3.1 Flash Image)
Both models represent a huge leap. You can now include your exact title, subtitle, and author name in a prompt and have them rendered correctly in the final image.
Better text rendering doesn't mean better covers automatically. These models are powerful...but they're only as good as the prompts they receive.
A vague prompt still produces a generic result.
To get a cover that actually fits your book, you need to know what to include, how to structure it, and which details make the difference between a cover that looks professional and one that looks like a template.
How to describe layout and composition - Where the title sits, how much visual weight it carries, how the imagery and text interact... these need to be specified deliberately.
How to communicate genre and mood - A thriller cover and a self-help cover are visually worlds apart. The model needs clear cues about tone, color, and style... or it defaults to something generic.
How to direct typography - The model can render text... but you need to tell it what font style, size relationship, and placement will make your title command attention.
How to iterate effectively - Getting from a first output to a final cover takes structured refinement. Knowing what to adjust, and how to say it, cuts that process from hours to minutes.
I built a tool that does ALL of that for you, automatically...
This product is all about creating great looking book covers, using the latest free AI tools: ChatGPT Image 2.0 and Nano Banana 2 (or any other AI image tool).
The new AI models are especially good at handing text now, which makes them perfect for creating book covers. And so I put together a toolkit that takes full advantage of these powerful new models, specifically for creating truly professional looking book covers.
With this toolkit I wanted to remove ALL the obstacles to creating a book cover image.
You don't need any Photoshop or Canva skills
You don't need any design skills at all
You don't need any tech skills
You don't need any prompting skills
You don't need a paid AI subscription (works with free models)
You don't even have to think about the type of layout to use for the book cover, what type of colors to use, what fonts to use, what image should be included, what size everything should be, etc..
The AI handles ALL the creative work (unless you want to give some specific input).
All of the "technical" stuff is handled behind the scenes. All you have to do is fill in the box that says "Your Book Details”. After that you just copy and paste the text file it generates, and that's all the "work" involved. The AI handles the rest.

Step 1: Describe Your Book - Type your book details in plain sentences inside the "Your Book Details" box and click Generate Prompt. No special format needed, just write naturally. The tool will instantly transform your plain sentences into a ready-to-use Master Prompt in perfectly structured JSON format, with your details built in.
Step 2: Paste Into Any AI Chat Tool - Copy the Master Prompt and paste it into any AI chat tool — ChatGPT, Gemini, Claude, Grok, or any other. Hit send. The AI will read the instructions and output a detailed, fully filled-in book cover image prompt. No extra typing needed.
Step 3: Paste Into Any AI Image Tool - Copy the prompt from the AI chat tool and paste it into any AI image generator — ChatGPT Images 2.0, Nano Banana 2, Midjourney, Imagen, or any other. It will generate a high quality, custom book cover image. Repeat as many times as you want.

Plain language used to describe the book:
"My book is called Fire & Forgetting. It's a war memoir. My name is David Crane. For the layout I want the title in large bold text at the top, a full-bleed image of a soldier silhouette in the center, the tagline in small italic text, and my author name at the very bottom in small clean text."

Plain language used to describe the book:
"Create a book cover in the Epic Fantasy genre. The main image subject is a lone hero standing at the edge of a vast landscape. The art style and medium is epic digital painting with sweeping brushwork, cinematic scale, and rich, saturated color throughout. You choose the book name and all other details and fill in the details using the master template."

The above are just a few examples of the type of covers you can create. The possibilities are endless. You can create a book cover for ANY genre, on ANY topic, in ANY style, etc.. This toolkit makes it easy.

With crisp text, cinematic visuals, textured overlays, and other
extra touches that make the cover look premium...

Or create simple and clean book covers without heavy textures and details...

The Prompt Builder is a stand alone light weight HTML file. You don't need any API keys, tokens or credits to use it. Use it unlimited times. Use it on free models.


With this toolkit you're not locked into any specific AI tool, so you can use any AI models you're already comfortable with.
The prompt builder comes as a stand alone HTML file. You download it to your computer and use it anywhere you like anytime you like.


The HTML prompt builder turns plain language into a detailed JSON prompt that's perfectly structured for AI to create a book cover.
Nothing gets lost or misinterpreted
In a long prose prompt, details at the end often get less attention than details at the start. JSON gives every field equal weight. The AI reads each one as a discrete instruction, not part of a stream.
Easy to reuse and adapt
Swap out one field: title, genre, mood... and the rest of the template stays intact. You're not rewriting the whole prompt for every new cover. Just update what changed.
Precise iteration
When a result isn't quite right, you know exactly which field to adjust. Change the mood from "dark" to "melancholic" and see the difference — without touching the layout, typography, or anything else.
Works cleanly across any AI chat tool
ChatGPT, Claude, Gemini, Grok — all of them parse structured JSON reliably. The format is universally understood, so the prompt performs consistently regardless of which tool you paste it into.
Scales across multiple projects
Build a library of JSON templates — one per genre, series, or cover style. Each one is a reusable asset, not a one-off prompt you have to reconstruct from memory.
