# AI Author vs Submos

AI Author and Submos 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. AI Author sells 3 in-app purchases, starting at $2.99 per 7 days and Submos sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

AI Author ships an update every 2 weeks, Submos every 9 days. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
