# PDF Translate Pro vs PDF AI

The clearest difference is rating: PDF AI at 4.6 against PDF Translate Pro's 4.1. PDF AI also leads on review sentiment (25% vs 0%). PDF Translate Pro's advantage is ads (none vs shown) and update cadence (every 8 days vs every 6 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. PDF Translate Pro sells 10 in-app purchases, starting at $2.99 per 7 days and PDF AI sells 6 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF AI holds the better App Store score, 4.6 against 4.1. That said, the two scores are not equally well evidenced: PDF Translate Pro has 291 ratings behind it against 24, so its average is the more settled of the two. Written reviews point the same way: 0% of PDF Translate Pro's written reviews are positive against 25% of PDF AI's.

PDF Translate Pro ships an update every 8 days, PDF AI every 6 weeks. The most recent releases landed on November 7, 2026 and November 8, 2026 respectively.
