# AI智能大师 vs 写作火火

AI智能大师 and 写作火火 are too close to call on the numbers: across 3 compared parameters — price, in-app purchases and iOS requirement 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. AI智能大师 sells 4 in-app purchases, starting at $6.99 per 7 days and 写作火火 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
