# 翻译狗 vs AI TransPDF

The clearest difference is review sentiment: 翻译狗 at 50% against AI TransPDF's 0%. 翻译狗 also leads on rating (3.6 vs 1.0) and update cadence (monthly vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 翻译狗 sells 14 in-app purchases, starting at $6.99 per month and AI TransPDF sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

翻译狗 holds the better App Store score, 3.6 against 1.0. That said, the two scores are not equally well evidenced: 翻译狗 has 7 ratings behind it against 1, so its average is the more settled of the two.

翻译狗 ships an update monthly, AI TransPDF every 2 months. Both last shipped on October 24, 2026.
