# Kai vs AI

The clearest difference is ads: Kai at none against AI's shown. Kai also leads on update cadence (every 3 days vs fortnightly). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

Kai ships an update every 3 days, AI fortnightly. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
