# Privacy AI vs BookWrite

The clearest difference is in-app purchases: BookWrite at none against Privacy AI's 3. BookWrite also leads on rating (5.0 vs 4.8). Privacy AI's advantage is ratings volume (20 vs 1) and update cadence (weekly vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Privacy AI sells 3 in-app purchases, starting at $3.99 per 7 days. BookWrite asks for nothing beyond the download.

BookWrite holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Privacy AI has 20 ratings behind it against 1, so its average is the more settled of the two.

Privacy AI ships an update weekly, BookWrite every 3 weeks. The most recent releases landed on October 13, 2026 and October 8, 2026 respectively.
