# 秘塔AI搜索 vs StepFun

The clearest difference is rating: StepFun at 4.3 against 秘塔AI搜索's 3.8. 秘塔AI搜索's advantage is review sentiment (59% vs 50%) and ratings volume (30 vs 8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 秘塔AI搜索 sells 13 one-off in-app purchases and StepFun sells 13 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

StepFun holds the better App Store score, 4.3 against 3.8. Both are backed by a comparable volume of ratings — 30 and 8 respectively. Written reviews complicate that: 59% of 秘塔AI搜索's written reviews are positive against 50% of StepFun'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, StepFun every 9 days. The most recent releases landed on October 16, 2026 and October 14, 2026 respectively.
