# AI写作 vs AI写作助手

The clearest difference is iOS requirement: AI写作 at 12.0 against AI写作助手's 15.6. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. AI写作 sells 4 in-app purchases, starting at $3.99 per 7 days and AI写作助手 sells 11 in-app purchases, starting at $14.99 per year. Whichever you choose, the download price is not the number that matters.
