# AIメールくん vs ビジネスメール定型文GPT

AIメールくん and ビジネスメール定型文GPT 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メールくん sells 1 in-app purchase, starting at $6.99 per 7 days and ビジネスメール定型文GPT sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
