# Sophia vs Notebook AI

The clearest difference is review sentiment: Sophia at 70% against Notebook AI's 0%. Sophia also leads on ratings volume (108 vs 3) and iOS requirement (18.0 vs 26.0). Notebook AI's advantage is rating (5.0 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sophia sells 13 in-app purchases, starting at $5.99 per 7 days and Notebook AI sells 2 in-app purchases, starting at $20.00 per month. Whichever you choose, the download price is not the number that matters.

Notebook AI holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Sophia has 108 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 70% of Sophia's written reviews are positive against 0% of Notebook AI's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 6 days. The most recent releases landed on October 16, 2026 and October 14, 2026 respectively.
