What If You Could Find Hidden Gold in the Coloring Book Market…
Before Anyone Else Sees It?

Let me tell you about a very specific kind of pain.

You've got an idea for a coloring book. Tropical birds, maybe. Or gothic mandalas. Or — who knows — cozy cottagecore animals.

So you do what every sensible person does. You open Amazon, type in your idea, squint at the results, try to figure out if anyone's buying this stuff, open seventeen more browser tabs, Google "how to research KDP niches", land on a YouTube video that's 47 minutes long and mostly talking about a tool that costs $99/month, close all your tabs, and go make a cup of tea.

Two hours later, nothing has happened. No book. No listing. No passive income. Just cold tea and that familiar feeling of "I'll start properly tomorrow."

That's exactly what I built this tool to fix.

Introducing the KDP Coloring Book Research Generator

It's a single offline HTML file. No app to install. No subscription to forget about. No API key to hunt down. You open it in your browser — yes, even without internet — and inside you've got three research weapons that used to take hours.

Fill in a form. Click a button. Get a perfect, structured AI prompt that you paste straight into ChatGPT, Claude, Gemini, or Grok — and get back a research brief that would make a full-time KDP analyst jealous.

The Niche Research tab — fill in a theme, pick your angles, hit generate.

Three Prompts. One Tool. Every Angle Covered.

The generator has three separate modes, each one targeting a different stage of your publishing process — and each one producing a prompt that would take you an hour to write yourself:

Module 01 — Niche Research Prompt

You type in a theme — "Coastal Birds", "Dark Fantasy Mandalas", "Cute Gnomes for Kids" — and the generator builds a full research brief prompt that asks your AI of choice to give you:

• Market Demand Score (out of 10) with a plain-English explanation of what it means for you
• Competition Level — Low, Medium, or High — so you know whether you're walking into a gunfight or an empty room
• Top 5 Sub-Niches to explore, ranked by sellability — each with a suggested angle or hook
• Ideal Buyer Profile — who buys this, when they buy it, why they buy it, and what makes them hit "Add to Cart"
• Seasonal Demand Calendar — exactly when to publish so you're ready for peak sales windows
• Competitor Gap Analysis — what books dominate this niche, what they're missing, and where you can walk straight through the gap
• Go / Proceed with Caution / Avoid — a final verdict with three clear reasons, so you never waste time building the wrong book

─────────────────────────────────────

with Caution", tell me exactly what I need to do differently...

That prompt — which the generator builds for you in about four seconds — usually comes back from your AI as a 1,000+ word research report. The kind of research that used to mean spreadsheets, Amazon scraping tools, and an entire Saturday morning.

Module 02 — Keyword Research Prompt

Once you've found your niche, you need to know exactly what your buyers are typing into the Amazon search bar at 11pm when they're looking for something to do with their hands.

This module generates a keyword research prompt that tells your AI to hand you:

• Up to 50 ranked keywords — with competition rating, monthly search volume, and buyer intent in plain English for each one
• Top 5 easiest-to-rank keywords — the ones where you can actually show up in search without a back catalogue of 200 books
• Long-Tail Gold — the Hidden Gems — 5 ultra-specific 4-7 word phrases that buyers actually use, but barely anyone is targeting
• Keywords to Avoid — the ones that look obvious but are buried under established players you have no chance of beating
• Keyword Placement Strategy — exactly which keywords go in your Title, Subtitle, Description, and Backend Tags

The Keyword Research tab — with the live Prompt Quality meter showing 82%.

Module 03 — KDP Listing Prompt

The last module is the one that makes the money. Because a great coloring book with a bad listing might as well be invisible.

You fill in your theme, design style, page count, and unique selling points — pick a copywriting tone (warm and friendly? urgent? benefit-led?) — and it generates a prompt that comes back with a complete, ready-to-paste Amazon KDP listing including:

• SEO-Optimized Title (under 200 characters, keyword-first, written to rank AND to sell)
• Subtitle with 2–3 secondary keywords woven in naturally
• Full Amazon Description (250–400 words, plain-text paragraphs, written to convert browsers into buyers)
• All 7 Backend Search Tags — each under 50 characters, zero overlap with your title keywords
• 2 Recommended Categories with full paths and reasons for each
• Pricing Recommendation — a specific dollar amount with a brief explanation of why

The Numbers That Actually Matter

What Changes When You Stop Guessing

There are two types of KDP coloring book publishers.

The first type publishes on vibes. They pick a niche because it feels good. They throw together a listing with whatever keywords come to mind. They publish and wait. And they mostly wait. And then they publish another one, with slightly more hope, and slightly less certainty.

The second type knows exactly what they're doing before they design a single page. They know the demand. They know the competition. They know who's buying and when. They know which keywords to chase and which to leave alone. And they write a listing that sounds like it was written for the exact person who just typed that search.

That's all this tool does. It gets you the right research. Fast. Without the faff.

The Prompt Quality Meter — Your Built-In Research Coach

Here's a detail I'm particularly proud of.

Every time you generate a prompt, the tool shows you a Prompt Quality score based on how much detail you've provided. The more inputs you fill in — your target audience, your marketplace, your research angles, any extra context — the higher your score, and the more specific and useful your AI research report comes back.

It's like having a research quality coach looking over your shoulder — nudging you toward better inputs so you get better outputs. Because a 91% quality prompt gets you research that a 43% quality prompt simply can't.

This Is For You If…

• You're building a passive income stream on Amazon KDP and want to stop guessing which niches are worth your time
• You've published coloring books before but never felt confident your research was thorough enough
• You're just starting out and want to avoid the classic beginner mistake of picking an oversaturated niche with no room for new entrants
• You already use ChatGPT or Claude for your publishing business but you're tired of writing your own prompts from scratch every time
• You want a one-time tool that works forever — no subscriptions, no updates to buy, no account to maintain
• You value your time enough to spend three minutes on research that used to take three hours

It Really Is As Simple As Four Steps

• Step 1 — Download the file. One HTML file. Lands in your downloads folder in seconds. No installation. No setup. Nothing to configure.
• Step 2 — Open it in your browser. Chrome, Firefox, Safari, Edge — it works in all of them. Works offline. Works on Windows, Mac, or Linux.
• Step 3 — Fill in your theme and hit Generate. Pick your module, enter your coloring book theme, choose your options, and click the button. Your structured AI prompt appears in the dark output box below.
• Step 4 — Copy and paste into your AI chatbot. Hit the Copy button. Open ChatGPT, Claude, Gemini, or Grok. Paste. Hit Enter. Read your research report. Publish smarter.

Questions I Know You're Thinking

"Do I need an API key?"

No. The generator creates prompts — structured text you copy and paste. You paste them into your existing free ChatGPT, Claude, or Gemini account. No API key. No paid tier required (though paid tiers will give you better output).

"Does it work on Mac / Windows / mobile?"

It works in any modern browser on any device. It's a single HTML file. If your browser can open a webpage, it can run this tool.

"Will it work after ChatGPT updates their interface?"

Yes. The tool generates text prompts. It doesn't interact with any AI platform's code or API — it just produces text you copy. That's future-proof by design.

"What if I'm totally new to KDP?"

Then this is arguably more useful to you, not less. The biggest mistake new KDP publishers make is picking niches on gut feel. This tool puts proper research in front of you before you've committed a penny or an hour of design time.

"What niches does it work for?"

Any coloring book theme you can type. Mandalas, animals, fantasy, nature, holiday-themed, kids, large print for seniors, mindfulness, architecture, floral, seasonal — any of it. You provide the theme; the generator builds the research structure around it.
