# CSV Quiz vs AI出題

The clearest difference is ads: CSV Quiz at none against AI出題's shown. CSV Quiz also leads on update cadence (every 5 days vs every 6 weeks) and iOS requirement (15.0 vs 18.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CSV Quiz ships an update every 5 days, AI出題 every 6 weeks. The most recent releases landed on October 16, 2026 and October 9, 2026 respectively.
