# 笔墨写作 vs AI办公助手

The clearest difference is iOS requirement: 笔墨写作 at 12.0 against AI办公助手's 14.3. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 笔墨写作 sells 13 one-off in-app purchases and AI办公助手 sells 10 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
