Verdict

The call

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.
