# AI社区 vs 青碳行

The clearest difference is ads: AI社区 at none against 青碳行's shown. AI社区 also leads on iOS requirement (10.0 vs 13.0). 青碳行's advantage is update cadence (every 4 weeks vs every 5 months). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

AI社区 ships an update every 5 months, 青碳行 every 4 weeks. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
