Not worth it.
I tried YouBooks so you do not have to.
It does exactly what it promises.
You give it a prompt.
It spits out a full length draft fast.
But that is where the value stops.
Here is the real problem I ran into.
It injected a ton of fake proof.
Not exaggerated proof.
Not slightly polished proof.
Straight up things that never happened.
Results I never claimed.
Stories I never lived.
Authority I did not earn yet.
That is not just annoying.
It is dangerous.
Now instead of writing, I am fact checking my own book.
Deleting paragraphs.
Untangling fake case studies.
Making sure I am not accidentally lying to the reader.
That is way more tedious than starting clean.
With GPT, Gemini, or Claude, I can:
Write one chapter at a time
Control the claims
Build proof only where it exists
Let the authority grow honestly with the audience
The irony is this:
The more “done” YouBooks made the book feel, the harder it was to trust or use.
Speed without control is not leverage.
It is friction.
If you already have:
A real audience
Real results
Real case studies
A clear positioning
Then maybe a tool like that saves time.
If you are still building, refining, or documenting your journey in real time, it creates more cleanup than progress.
My takeaway:
I would rather write slower with truth than faster with fiction.
If you are thinking about using YouBooks, just know what you are buying.
You are not buying a finished book.
You are buying a rough draft that still needs a grown adult to clean up every claim.

Edited Dec 13, 2025Thanks for the review. Youbooks does not know your journey, your cause, your brand, unless you are famous. The alternative would be kind of freaky, if you think about it.
If you ask youbooks to write 200K words on how to relocate to Mars, it will do that. However, because there is little factual evidence on how to do that, it will come up with a lot of stuff.
We once tested it with generating a biography for a friend of mine, who is a mini celebrity in Greece; however, there is not enough factual knowledge on the internet to write about him. We asked for 50K words, and the result was more or less what you described.
Youbooks can write on subjects the LLMs know about, or, is on the internet, or, you provide sources on. It's best to be able to tick all these boxes. If these do not hold, the only alternative you have is what you suggested, a human-in-the-loop approach that takes way more time to complete, but is the only viable approach anyways.
