# Chat Mind vs AI写作

The clearest difference is update cadence: Chat Mind at every 5 days against AI写作's every 3 weeks. AI写作's advantage is iOS requirement (12.0 vs 15.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Chat Mind sells 4 in-app purchases, starting at $2.99 per 7 days and AI写作 sells 4 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Chat Mind ships an update every 5 days, AI写作 every 3 weeks. Both last shipped on November 3, 2026.
