# AE Note vs AI PDF

The clearest difference is update cadence: AI PDF at weekly against AE Note's monthly. AI PDF also leads on device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. AE Note sells 4 in-app purchases, starting at $4.99 per month and AI PDF sells 2 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AE Note ships an update monthly, AI PDF weekly. The most recent releases landed on September 20, 2026 and September 23, 2026 respectively.
