# AI Writeon vs PDF Aide

The clearest difference is update cadence: PDF Aide at every 3 days against AI Writeon's every 13 months. AI Writeon's advantage is device support and iOS requirement (12.0 vs 15.6). On price and in-app purchases there is nothing between them.

Both are free to download. AI Writeon sells 1 in-app purchase, starting at $3.99 per month and PDF Aide sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

AI Writeon ships an update every 13 months, PDF Aide every 3 days. The most recent releases landed on October 3, 2026 and October 1, 2026 respectively.
