I have tested this app with the free 10-credit version, and although the app owner said this app is not yet really ready for fiction books, I decided to create a 9-chapter fantasy book about an apprentice witch in an adventure in search of magical artefacts. It is a draft of around 7,000 words, and it is a very fascinating storyline. I was impressed by the quality. Testing the same kind of story in ChatGPT, in Bard and Claude gave me also nice stories, but the quality was not better than what I got with Magic Bookifier. This made me decide to buy 4 codes, I believe this app will be fantastic when developed further and I have no doubt the owners will continue to develop this. Highly recommended for anyone who wants to write books in fiction and non-fiction!
