# 秘塔AI搜索 vs 纳米AI

The clearest difference is rating: 纳米AI at 4.3 against 秘塔AI搜索's 3.8. 纳米AI also leads on ratings volume (211 vs 30). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. 秘塔AI搜索 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.

纳米AI holds the better App Store score, 4.3 against 3.8. That said, the two scores are not equally well evidenced: 纳米AI has 211 ratings behind it against 30, so its average is the more settled of the two. Written reviews complicate that: 59% of 秘塔AI搜索's written reviews are positive against 54% of 纳米AI's, so the app with the better star average is not the one people write more warmly about.

秘塔AI搜索 ships an update every 10 days, 纳米AI weekly. The most recent releases landed on September 22, 2026 and September 24, 2026 respectively.
