Watch Casper write a book from idea to finished manuscript
Two things stop most expert books from getting written.
Finding the time
Making it sound like you
You have spent years building expertise. Clients trust your judgment. Colleagues ask for your advice. The book is in your head, but between the work, the family and the blank page, it never gets written.
So you price out a ghostwriter and see five figures. You look at a writing course and see months. You try a generic AI tool and get text that sounds nothing like you.
All you wanted was a book with your name on it that wins clients, lands talks and opens doors.
First Book ai removes both problems. Here is how.
From a few questions to a published book, in 5 steps.
Built around your knowledge and your own stories. Not generic. Not robotic. Yours.
Answer a few questions
Your topic, your audience, your tone and the stories only you can tell. No prompts to write, no blank page.
Guided like a conversation: the AI suggests ideas and angles and asks the right questions.
Approve your outline
You get an outline of 8 chapters, each with 3 subchapters, with a clear purpose behind every section. Rename, reorder or reshape it before anything is written.
Get chapters in your voice
Each chapter is drafted from your writing sample. Read it, edit it, rewrite it or check its tone. Nothing moves on until you approve it.
Write in 12 languages, and switch a finished book to another in one click.
Cover, export, publish
A professional cover is generated for your book. Export to Word, EPUB, Markdown or PDF, ready for Amazon KDP or your editor.
You own 100% of every manuscript. Your inputs and drafts are never used to train AI.
Finish it with Author's Club
The manuscript is done. Now edit, publish and launch it with the First Book ai team and 400+ authors from around the world behind you.
What authors say
"Assisted my team with addressing the stigma associated with addictions and mental health."
What I liked about the product is I could come up with an idea and a basic concept of what I needed, as well as feed it stories from my previous caseload and life experiences, and it would allow me to create a book that I would oftentimes just give out at trainings and at conferences, as well as at shelters and recovery centers.
MisterTherapistVerified purchaserAmazing! Already booked my first conference.
The platform is really easy to use. The time it takes to start writing and finishing a book is unbelievably fast and highly accurate when moving from chapter to chapter.
jorge12Verified purchaserActually delivers.
I have tried a number of these book writing deals. This one actually delivers end to end. I have actually managed to get out 12 books so far and nobody has complained about the quality.
DmsukVerified purchaserEvery book comes with a cover. Readers do judge.
A professional cover is generated for every book, ready for Amazon KDP, print or a PDF you hand to clients.
Example covers with fictional titles and authors, for illustration.
A lead magnet, a Kindle book or a leave-behind for clients. It looks like you meant it.

Why I built this.
And what it has done for the people using it.

I'm Casper. I wrote and published my first book myself. It was eye-opening, and full of challenges I did not see coming. Talking to other writers, I found they hit the same walls. First Book ai is the tool I wanted back then.
Jeremy has ADHD. In his review he wrote that First Book ai kept him on track, organized his thoughts, and made him successful.
One buyer had wanted to write a book for more years than they would like to admit. They finished the first draft of their very first book.
If your book has been on the list for years, this is the shortest way I know to get it written.

Authors, coaches and consultants on what writing with First Book ai was like. Rated 4.3/5 from 76 reviews on AppSumo.
I am impressed.
Wow I am so impressed with the creativity and flow of ideas generated by this software, it has made for me what always seemed to be such a daunting task of writing a book become achievable. My aim in writing is to establish credibility and position myself as the expert in my professional field. The chapter by chapter reviews enabled me to edit and add personal touches. The built-in cover design really makes it easier in creating a finished book.
It brings out what you already have in your mind. It articulates your vision. It is your voice, refined.
Recommended for nonbusiness or nonfiction writers.
I like that it helps us through a guided, question-based workflow. Fast book creation: helps turn an idea into an outline and draft quickly.
fngVerified purchaserSaved a ton of time and gave me a solid foundation.
It was incredibly helpful in giving me a strong beginning for a book I've been working on and saved me a huge amount of time in the process. It was easy and intuitive to use, and gave me something substantial to work from rather than starting from scratch. I definitely recommend it.
As someone with ADHD, this app has been a huge help keeping me on track, organizing my thoughts, and making me successful. Highly recommend!
I've been wanting to write a book for more years than I'd like to admit. First Book ai made everything so much easier. It feels like having a helpful coach right there with you. I was finally able to write the first draft of my very first book.
Great platform to build a passive income channel and gain some recognition.
This platform has allowed me to build a passive income revenue channel that I previously thought was difficult to achieve. Once the entire book is created, consisting of around 50,000 words and eight chapters, the files needed for publication are easy to manage.
germankyVerified purchaserI wasn't sure how to kick things off. When I found First Book ai, I just knew it would click, and it totally did. No more writer's block. My outline is sparking really thoughtful ideas.
I use it to create business books and coaching material. It saves hours. Clean interface, fast output. Ideal for coaches, consultants, and aspiring experts.
One of the best tools I've purchased. The content is easy and editable. A great way to get things started. I'm a customer for life.
You get all the research done and a first draft in record time. I'll be using it to publish a few books for sure.
First Book made it super simple to start. The first draft shaved years off the process. Perfect if you have ideas but no clue how to structure a book.
The team is committed to improving. Support has been outstanding. Great transparency about the roadmap and planned improvements.
