WATCH HOW IT WORKS

Here's how I make it easy
to turn thrillers into income.

HI, I'M KATE RILEY

Let me show you the fast and easy way
to write thrillers that sell.

You know the feeling. It's past midnight, you promised yourself one more chapter, and now you're checking the locks before bed. That's a thriller doing its job.

Thriller readers are some of the hungriest buyers in fiction. They finish a book in 2 sittings and go straight back for the next one, and a series with a hero they trust keeps them buying book after book.

I've published fiction across multiple pen names, with books on the New York Times and USA Today bestseller lists. I know how much planning sits underneath a story that feels effortless to read, and I've turned that planning into a course you can follow with Claude or ChatGPT.

Your AI does the work and recommends every step. You're the director who approves it. I show you exactly which command to run at each step, so you always know what to do next.

You get the system, the plugin and the prompts. You don't need to be a writer or a big reader.

WHY THRILLER READERS BUY BOOK AFTER BOOK

Write the books that are proven winners.
Write them faster with AI.

A dead body and a detective are a fine start. What keeps readers turning pages is a protagonist with something to lose, a villain who thinks they're the hero and a clock that won't stop.

Your AI builds the tension and the twist as parts of the same machine. Every clue is planted on purpose. Every red herring misleads without lying. When the reveal lands, your reader flips back and sees it was there the whole time.

Your AI starts by finding your most profitable lane, then recommends your tropes, your content level and your concept from 10 scored options. From there it builds the protagonist, the villain, the stakes and the twist, one step at a time, for you to approve.

It's your own thriller, with a system that keeps every piece honest.

NO IDEA, NO EXPERIENCE, NO PROBLEM

Every roadblock between you and “The End”,
handled for you.

NO IDEA YET?

Find a concept worth a whole book

Your AI studies what's selling, generates 10 concepts and scores each one, so you start with the strongest hook instead of the first idea that came to mind.

TOO MUCH TO TRACK?

Give your thriller a memory

A Twist Bible, a clue tracker and a living series bible tell your AI who knew what and when, so your timeline never breaks and your twist stays fair.

GENERIC AI PROSE?

Build your own author voice

The Voice Builder studies the top sellers in your lane and recommends a voice, so your chapters sound like your pen name and not like a robot.

The course shows you a sample thriller, The Second Key, so you can see every decision in context. You'll follow a court stenographer who notices what people leave out, while building a completely different book of your own.

Your AI drafts the words. You read, review and approve. Each lesson shows you the command to run, what your AI will do and what to look for before you approve it.

THE COURSE PLUGIN IS INCLUDED

Write your thriller novel in half the time
with our powerful Thriller Writer plugin.

MANUAL MODE

Learn what each step does

Copy the ready-made prompts into your AI, read the result, ask for changes and save the version you approve.

SHORTCUT MODE

Let Thriller Writer do it

The Thriller Writer plugin automates the whole process. One command asks the right questions, builds your documents and saves them, so you get through the course in a fraction of the time. A $197 plugin, free with the course.

Write It course artwork

Start with Shortcut Mode, because that's what every video walks you through. Prefer to paste the prompts yourself? Manual Mode has its own tab on each lesson. You can mix both ways throughout the course.

Thriller Writer is a $197 plugin, and it's included free with the course, with versions for Claude and ChatGPT and the install steps inside the download. You also get the Thriller Genre skill, which teaches your AI every lane, trope and structure rule, and the Voice Builder skill for your pen name.

The course works with either AI. The lessons explain where the steps differ, so you can follow the tools you already use.

BOOK 1 IS THE BEGINNING

One thriller sells the next.
Build the series that pays.

You're planning beyond the first book from the start. Your hero, your lane and your unanswered questions all have somewhere to go.

The course guides you to a drafted and edited Book 1 of about 80,000 words, plus a Twist Bible, a series bible and a series plan that make Book 2 easier than Book 1.

Then your AI prepares your title, blurb and keyword phrases, and plans your cover, all studied against the live top sellers in your lane. Your book is ready for the readers your AI researched.

A reader who finishes Book 1 at 2 in the morning has a next book to buy. That's the publishing opportunity we're building toward, one honest twist at a time.

A FEW THINGS YOU MAY BE WONDERING

Let's clear these up.

Do I need a book idea before I start?

No. Your AI studies what's selling, generates 10 concepts and scores them, then recommends the strongest one.

Do I need to have written a thriller before?

No. Your AI does the writing, and each lesson shows you the command to run. You just read and review what it produces.

Which kind of thriller can I write?

Any of 10 lanes: domestic, psychological, crime, legal, medical, political, spy, techno, action and romantic suspense. Your AI recommends the most profitable one for you. You can choose any lane you like, but if you're new, I recommend letting the data decide.

Does this work with Claude or ChatGPT?

Both. The course explains where their workflows differ, and Thriller Writer, the Thriller Genre skill and the Voice Builder skill include versions for both.

Is Thriller Writer included?

Yes. The course download includes the Claude and ChatGPT versions with the install steps. You can also use the manual prompts throughout.

Can I watch the lessons or read them?

Both. Every lesson has a video walkthrough and a written version. The hub saves your video position so you can return and resume.

How dark or violent does my book have to be?

Your AI recommends a content level from 1 to 5, based on what's selling in your lane. You approve it or set a hard limit, and your AI keeps every scene inside it.

Will I finish the whole series during the course?

The course guides Book 1 through drafting and editing, builds your series bible and shows you how to plan and write the books after it. Your pace depends on your review, decisions and writing time.

Does this cover publishing and book marketing?

It covers the fair-play audit, the polish pass, your title, blurb, keywords and cover. The course's focus is planning and writing your thriller series. Dedicated launch and marketing training is a separate offer.

What if I get stuck?

Ask Detective Marx inside the lesson. You can ask up to 10 questions a day, with a route to the support team after that.

Can you promise book sales?

No. Reader demand, the quality of your finished book and how you publish and promote all affect results. The course teaches the process; it doesn't guarantee income.

YOU DON'T NEED TO FEEL READY TO START

The next thriller readers binge
could have your name on it.

You don't need a twist, a villain or a folder full of notes before you join. Those are things we build together.

Start with the lessons. Your AI finds the lane with the most room for you. Let your AI handle the work while you approve every step.

Your hero. Your twist. Your series. A clear next step whenever you're ready.
