# 笔墨写作 vs 纳米AI

The clearest difference is review sentiment: 笔墨写作 at 100% against 纳米AI's 54%. 笔墨写作 also leads on rating (5.0 vs 4.3) and iOS requirement (12.0 vs 15.0). 纳米AI's advantage is ads (none vs shown) and ratings volume (211 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. 笔墨写作 sells 13 one-off in-app purchases and 纳米AI sells 14 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

笔墨写作 holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: 纳米AI has 211 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of 笔墨写作's written reviews are positive against 54% of 纳米AI's.
