# UPDF vs AI Note Taker

The clearest difference is rating: AI Note Taker at 5.0 against UPDF's 4.6. AI Note Taker also leads on review sentiment (100% vs 84%). UPDF's advantage is ratings volume (699 vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. UPDF sells 13 in-app purchases, starting at $9.99 per month and AI Note Taker sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AI Note Taker holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: UPDF has 699 ratings behind it against 4, so its average is the more settled of the two.
