# 秘塔AI搜索 vs EchoRead

The clearest difference is rating: EchoRead at 5.0 against 秘塔AI搜索's 3.8. EchoRead also leads on review sentiment (100% vs 59%). 秘塔AI搜索's advantage is ratings volume (30 vs 4). 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 EchoRead sells 8 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
