# PDF AI vs PDF

The clearest difference is rating: PDF AI at 4.6 against PDF's 4.0. PDF AI also leads on ratings volume (24 vs 1). PDF's advantage is ads (none vs shown). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. PDF AI sells 6 in-app purchases, starting at $2.99 per 7 days and PDF sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

PDF AI holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: PDF AI has 24 ratings behind it against 1, so its average is the more settled of the two.

PDF AI ships an update every 6 weeks, PDF every 2 months. Both last shipped on October 30, 2026.
