# ChatEngine vs CreatorBio AI

The clearest difference is iOS requirement: CreatorBio AI at 13.0 against ChatEngine's 16.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ChatEngine sells 11 in-app purchases, starting at $7.99 per 7 days and CreatorBio AI sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
