# 笔杆文库 vs AI写作机器人

The clearest difference is device support: AI写作机器人 at 3 against 笔杆文库's —. On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. 笔杆文库 sells 5 in-app purchases, starting at $4.99 per 7 days and AI写作机器人 sells 4 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
