# AI Pro vs ChatBrief

The clearest difference is update cadence: ChatBrief at every 2 days against AI Pro's weekly. ChatBrief also leads on iOS requirement (13.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. AI Pro sells 9 in-app purchases, starting at $0.99 per 7 days and ChatBrief sells 1 in-app purchase, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

AI Pro ships an update weekly, ChatBrief every 2 days. The most recent releases landed on October 15, 2026 and October 14, 2026 respectively.
