# PDF Scanner AI vs iDocument Scanner

The clearest difference is in-app purchases: iDocument Scanner at none against PDF Scanner AI's 3. iDocument Scanner also leads on iOS requirement (13.0 vs 16.0). PDF Scanner AI's advantage is ads (none vs shown) and rating (4.6 vs 4.2). On price, review sentiment and device support there is nothing between them.

Both are free to download. PDF Scanner AI sells 3 in-app purchases, starting at $2.99 per 7 days. iDocument Scanner asks for nothing beyond the download.

PDF Scanner AI holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: PDF Scanner AI has 259 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 94% of PDF Scanner AI's written reviews are positive against 100% of iDocument Scanner's, so the app with the better star average is not the one people write more warmly about.

PDF Scanner AI ships an update every 5 weeks, iDocument Scanner every 3 months. The most recent releases landed on October 13, 2026 and October 2, 2026 respectively.
