GhostAI: Train a Custom AI to Write Like You, and Pair With It to Write Your Computer Programming Book, Business Book or Corporate Marketing Communications Material

Who is GhostAI For?

GhostAI is a groundbreaking service in private beta that allows authors to train a custom Large Language Model (LLM) to write in their unique style. By leveraging advanced AI technology, GhostAI helps authors overcome writer's block, generate new ideas, and enhance their writing process using AI that sounds like they do.

With GhostAI, you can create a personalized AI writing assistant that understands your voice and tone. This AI companion can write like you, not like ChatGPT, even if you used ChatGPT to help you do the writing itself.

If you're producing computer programming books, business books or corporate marketing communication material, GhostAI might be a good fit for your needs.

To discuss whether GhostAI is a good fit for you and join the GhostAI private beta waiting list, please click the button below to schedule a discovery Zoom call with a Leanpub founder...

Simon Brown

“I love that Leanpub makes writing and publishing a beautiful book so simple. I no longer spin my wheels with layouts and formats - Leanpub gets out of the way when it's time to write, and then automates everything when it's time to publish.”

Daniel Root
Author, Trello Dojo

“With Leanpub, the first person who purchased my book for $9.99 almost two years ago (and only received a preface, and two short intro chapters) has had access to almost every bit of knowledge I've gained in those two years, and *that's* the value.”

“While most eBook exporter apps today can generate PDF files and many support ePub, there's one tool we recommend above all after trying 8 of the most popular: Leanpub.”

Matthew Guay
Content Marketer at Zapier

Finally, a royalty rate that puts authors first.

When you publish your book with Leanpub,
you earn an 80% royalty.

Why is this royalty rate important? It means you earn $16.00 on the sale of a $20.00 book. If you worked with a conventional publisher who sold your book for $32.00, you'd typically make just $1.60! (The publisher would usually get about $16.00, and you would get about 10% of that.) With royalty rates this high, people will actually choose to pay more since they can see how much you will earn as an author.

You are free to publish your book elsewhere at the same time as you publish it on Leanpub. However, other platforms may not allow you to publish in two places at once. If you want to try an exclusive service, you can "retire" your book on Leanpub any time, and you can also come back and "unretire" your book if you conclude you were making more money on Leanpub.

You set your own prices using our variable pricing model and you can change them anytime. This means you can instantly change your prices in response to audience feedback or special events. It also means you can increase the price of your book over time, as you add more content, which is a great deal for people who buy your book early on.

If you publish your book on Leanpub, we will not get in the way if you later want to publish with a conventional publisher. In fact, this is a great outcome and it is one of the reasons Leanpub exists. We want unknown writers to be able to publish their books before they're finished, build an audience while they're writing, and then optionally go after a publishing contract. Some publishers may even let you publish your book on Leanpub until you finish it, and then take up the book into their own process when the time is right. That's exactly what happened with this book. (If you're worried that a publisher won't accept a book that's already been published on Leanpub, then you should make sure to ask them before you publish here!)

Earn $8 on a $10 Purchase, and $16 on a $20 Purchase

We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98. You earn $8 on a $10 sale, and $16 on a $20 sale. So, if we sell 5000 non-refunded copies of your book for $20, you'll earn $80,000.

(Yes, some authors have already earned much more than that on Leanpub.)

In fact, authors have earned over $14 million writing, publishing and selling on Leanpub.
