I have two original audiobooks on this app that are doing well. The narration does rewrite what is uploaded, but for the most part it gets the story right. Sometimes it will read what I wrote word for word, other times it summarizes. I think that it would be better for writers if it stuck to how the story is written. The AI narrators are surprisingly realistic. The app is quite limited, though. It would be nice if readers could leave comments, likes and ratings. A creator dashboard that includes analytics would also be useful. Allowing free trials for readers and creators would boost downloads and purchases. I think this app has a lot of potential and hope it continues to improve and introduce new features like the ones I mentioned.
SUPPORT AUTHORS NOT CHEAPLY MADE AI APPS! The only reason I give this 5 stars is in the hopes that you all see this … this is in fact a 0/5 stars app because this is just AI trash DO NOT SUPPORT THESE APPS! Support the authors that write the books PLEASE… I understand it’s tempting to “ watch the books” but it’s not worth your time or money. I downloaded the app just to see how horrible this really is and you can’t even watch without paying for a subscription. There’s zero permission from the authors to publish their books in this way. We all like to talk about red flags so let’s make this simple for you 🚩#1- publishing books without authors permission 🚩#2: you have to pay to watch stolen content from real authors 🚩#3: it’s AI trash 🤖🚮 Please please please do not support this app if you can report it! Also if your still not convinced think about this for a second- your about to dump money to watch trash content that’s stolen… I’m sure this app will be taken down at some point so your going to throw away your money… YOU WILL NOT HAVE ACCESS TO THIS APP FOREVER IT WILL BE TAKEN DOEN FOR COPYRIGHT REASONS!!! ⚠️⚠️⚠️
I downloaded BookTok after being impressed by the initial sample trailer it generated from my book’s prologue. The idea of turning written work into a short cinematic trailer is genuinely exciting, and the demo made the app look polished and capable. Unfortunately, the experience immediately fell apart after subscribing. There is no functional free version—once the sample is generated, the only option is to subscribe. I paid for the $9.99/month plan, which includes a set amount of “gems” required to generate videos. That system would be fine if the app actually worked. Every attempt to create a video resulted in a “failed to create video” error. Despite this, the app still consumed all of my gems. I did not receive a single usable video. No retries, no refunds of gems, no successful output—just errors and a depleted balance. At that point, the app had effectively taken my money without providing the service it advertises. This is especially frustrating because the core idea is strong. The demo proves the app can produce impressive results—but in its current state, the paid functionality is unreliable at best and deceptive at worst. I would not recommend subscribing until the failure issue is fixed and there is a clear policy for refunds or restored gems when the app fails to deliver what you’ve paid for.
What if you could watch the world's greatest books like they are TV shows or movies? It's not just a book summary app -- it's a new way to learn with...
