Absolutely awesome!
Okay lets put the bottom line up front. After creating several manuscripts, I would buy it again in an instant. I bought the highest tier (5). I have played with this app and found that it does what it says it's going to do. I wanted more information on emotional non-reactivity. Not boundaries, not stuff about Buddha and lunar cycles and feelings and positive attitudes or any of that more nuanced perspective. I wanted facts and actionable advice. I got it in less than 2 hours.
The output explained everything from neuroplasticity to actionable steps. I was shocked at the detail and in-depth work it created and wondered if the ai was making stuff up. So I used Perplexity, Google and more tools to find sources that I could verify. The book does indeed follow current knowledge and advice. I can't ask for more. This is exactly what I wanted.
I don't have any feedback other than I want the quality output to stay the same. New features are great an all, but not if those features detract from the detail and depth I am currently getting. I really hope they are around for the foreseeable future so I can keep using this awesome tool.

Apr 13, 2026Thank you for sharing your experience and for the kind words - also for actually fact-checking the output. That means a lot to us!
Knowing the content holds up against Perplexity/Google, etc. is exactly the bar we're building to, and hearing that it does gives us a real boost.
Your point about quality is noted and taken seriously. New features won't come at the cost of depth and accuracy....

It really does work
It worked as advertised. I was able to get a book in an afternoon (would have been faster if I didn't keep leaving while it worked). What I really liked was it provided ideas I never thought of and added context to the main points.

Literally bought First Book AI and 2 days later published my book I'd been writing for 20 years
I have been writing my book for the last 20 years and it's basically a blue print for men and women navigating domestic abuse economic legal and emotional. And it gives a clear step by step blue print to enable the victim to take off the victim hoodie and stand in their power and do what's needed to move forward. This helped me polish it all up and I was able to move forward quickly. It just went available today and someone has already bought a copy. Time will tell now but thank you Casper 😊 and iv joined the skool group too. Just waiting to be accepted

Mar 29, 2026Thank you for sharing this. That’s a big milestone.
20 years of work turned into a finished, published book in a few days is exactly the kind of outcome we want to enable.
Glad to hear it helped you bring everything together and move forward. And great to have you in the Skool community as well - you're in now :)
Wishing you a strong launch. Let us know if we can help in any way!

Best AI book writer I've used to date
I used First Book AI just as a test, honestly, as I've actually just finished my first draft of my actual book. That one required analysis and setting of themes from actual transcripts of interviews so with that I had to use multiple AIs actually. The final one was predominantly done with Perplexity but I wanted to test out First Book AI just to see what sort of draft you could put together on the same topic without all those detailed transcriptions. Honestly it was pretty good.
Overall I think it's a great tool to use for your first draft and then to do your own editing and adding your own personality from that really good product, a lot better than the other AI book writing software that I've tried in the past, which was fairly useless actually.

Mar 28, 2026Thank you for taking the time to share this. Really appreciate the comparison as well.
Glad to hear it gave you a solid draft to work from. That’s exactly where we aim to be useful.
And you’re spot on. The best results come when you build on top of the draft with your own edits and voice.
We’ve also built a Skool community to help with the next steps. Finalising, refining, and getting the book...
