# AI Writer vs Book Creator

The clearest difference is review sentiment: AI Writer at 62% against Book Creator's 0%. AI Writer also leads on rating (4.7 vs 4.0) and monetization model (free with in-app purchases vs subscription). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. AI Writer sells 7 in-app purchases, starting at $9.99 per 7 days and Book Creator sells 8 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AI Writer holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: AI Writer has 1.1K ratings behind it against 27, so its average is the more settled of the two. Written reviews point the same way: 62% of AI Writer's written reviews are positive against 0% of Book Creator's.

AI Writer ships an update every 2 months, Book Creator monthly. Both last shipped on November 12, 2026.
