# Cortex vs ChatAI工具

The clearest difference is iOS requirement: Cortex at 15.1 against ChatAI工具's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Cortex sells 7 in-app purchases, starting at $4.99 per 7 days and ChatAI工具 sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
