# Dou AI vs Smart Chat

The clearest difference is monetization model: Smart Chat at free with in-app purchases against Dou AI's subscription. Smart Chat also leads on update cadence (every 4 days vs monthly) and rating (4.4 vs 4.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Dou AI sells 4 in-app purchases, starting at $4.99 per 7 days and Smart Chat sells 8 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Smart Chat holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Smart Chat has 1.2K ratings behind it against 4, so its average is the more settled of the two.

Dou AI ships an update monthly, Smart Chat every 4 days. The most recent releases landed on October 9, 2026 and October 22, 2026 respectively.
