# 秘塔AI搜索 vs XThinkTank

秘塔AI搜索 and XThinkTank are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. 秘塔AI搜索 sells 13 one-off in-app purchases and XThinkTank sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

秘塔AI搜索 ships an update every 10 days, XThinkTank every 9 days. Both last shipped on October 25, 2026.
