I Made $500+/Month From AI KDP By Targeting Fictional Character Fans

​

​

I've been testing a pretty simple KDP method that I don't see talked about much here.​

The idea is basically to take something that already has a huge amount of attention on TikTok, fictional characters that people are obsessed with and turn the traits people admire about those characters into a self-improvement book.

Think the type of character where teenagers see an edit and think "I want to be like this guy."

James Bond-type charisma.
Batman-type training principles
Jordan Belfort-type confidence

Obviously, you don't want to just take a copyrighted character, slap their face on a book and upload it to KDP. That's asking for problems.

The trick is using the idea and archetype, not copying the actual IP.

For example, instead of making a book called "Become Batman", you could make something like "The Vigilante Mindset: Discipline, Confidence and Mental Toughness" and build the entire book around the traits people associate with that type of character.

The character is basically the marketing hook.
The actual product is self-improvement.

Making the book​

This is where AI makes the whole thing ridiculously easy.

I don't just tell ChatGPT "write me a book about confidence" because you'll get the usual generic AI slop that everyone else is producing.

Instead, I ask ChatGPT to create a massive master prompt for an advanced writing model. The prompt covers the target audience, positioning, book structure, tone, chapter objectives, examples, exercises, research requirements and everything else needed to produce an actual non-fiction book.

I'll then feed that prompt into whichever advanced model I'm using at the time such Claude Fable, Astra 6, etc.

The important part is that the AI isn't being asked to write random chapters. It's being given a complete brief for what the finished product should accomplish.

For example, if the concept is based around becoming more charismatic, the book could go into confidence, conversation, body language, social awareness, storytelling, emotional control, listening, presence and practical exercises.

The character archetype gives the book a personality and makes the subject interesting.

After the AI produces the manuscript, I go through it and clean it up. This is important because you don't want something that obviously reads like it was generated in 30 seconds.

I'll remove repetitive sections, fix awkward wording, improve examples and make sure the advice actually makes sense. The goal isn't to create the world's greatest self-improvement book.

The goal is to create something that looks and feels like a legitimate book when someone finds it on Amazon.

The cover​

Once the manuscript is finished, I'll have AI create the KDP cover as well. This is another area where you shouldn't just accept the first thing AI gives you. The cover needs to be designed for the actual KDP specifications and, more importantly, it needs to work as a tiny Amazon thumbnail. Someone should be able to look at it for half a second and understand what the book is about.

I'll check the dimensions, resolution, text, margins, spelling and final file before uploading it. A good-looking cover makes a massive difference because the person coming from TikTok isn't necessarily looking for your book.

You've got to make them stop and think, "What's this?"

Publishing​

Then it's simply uploaded through Amazon KDP.

I price the book so that I'm making at least $1.99+ in royalty per sale after Amazon's cut.

I'm not interested in making 30 cents per sale just to say I sold a bunch of copies.

The whole point is that every sale should leave enough profit for the traffic method to make sense.

I also don't rely on countdown deals or anything complicated.

The book needs to be able to sell normally.

Getting the traffic​

This is probably the most interesting part.

Once the book is live, I go to TikTok and search for the type of content that my target reader is already watching.

If the book is based around a secret-agent type character, I'll search things like "James Bond edits", "spy edits", "charisma edits", etc.

If it's around discipline, I'll search for the relevant character edits, motivation videos and mindset content.

Then I sort by newer uploads that were made 24 hours ago.

There are constantly new edits being uploaded, so you're basically tapping into an audience that already exists rather than trying to build one from scratch.

I'll watch the videos and, where it's genuinely relevant, leave a casual comment that mentions the book.

Something along the lines of:

"This is basically what [BOOK TITLE] is about lol"

Or:

"The stuff in [BOOK TITLE] about this is actually interesting "

Or:

"I've been reading [BOOK TITLE] and now every edit makes more sense lol"

The wording gets changed around rather than posting the exact same comment everywhere.

I also wouldn't recommend pretending to be a random customer or falsely claiming you've read something you haven't. There's no reason to build the method around deception when simply making the book part of the conversation can work.

The objective isn't necessarily to get a direct click.

It's to get the book title into somebody's head.

Someone sees an interesting character edit.

They see a comment mentioning a book related to it.

They get curious.

They search the title on Amazon.

They land on the listing.

If the cover looks professional and the book description is good, you've got a chance at the sale.
That's the entire funnel.

The numbers​

When I was actively doing this, I was commenting on 20+ relevant videos a day and got the book to $500+ per month.

I eventually stopped actively promoting it.

What's interesting is that it didn't immediately go to zero.

That same book still makes roughly $50–$100/month despite me not actively pushing it anymore.

That's what made me realise the interesting part isn't necessarily the individual comment.

It's building an asset that can continue getting discovered on Amazon after you've done the initial promotion.

Scaling it​

Once you understand the formula, you can apply it to completely different concepts.

You find an archetype people already care about, identify the trait they're attracted to, turn that trait into a useful self-improvement topic, build the book with AI, make a professional cover, put it on KDP and then go where that audience already spends its time.

The mistake would be mass-uploading hundreds of garbage AI books and hoping something sticks.

I'd rather have 10 books with genuinely strong concepts than 100 books nobody wants.

The formula is basically:

Character obsession → desired trait → useful transformation → AI-assisted book → KDP → TikTok discovery → Amazon search → sale.

It's a very simple model, but the interesting part is that you're not trying to manufacture demand.

You're attaching your product to demand that already exists.
