# Chat AI vs ChatGPT

The clearest difference is ratings volume: ChatGPT at 11M against Chat AI's 1.1K. ChatGPT also leads on rating (4.8 vs 4.6) and chart position (#1 vs unranked). Chat AI's advantage is iOS requirement (15.0 vs 18.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Chat AI sells 4 in-app purchases, starting at $7.99 per 7 days and ChatGPT sells 8 in-app purchases, starting at $8.00 per month. Whichever you choose, the download price is not the number that matters.

ChatGPT holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: ChatGPT has 11M ratings behind it against 1.1K, so its average is the more settled of the two. Written reviews complicate that: 74% of Chat AI's written reviews are positive against 70% of ChatGPT's, so the app with the better star average is not the one people write more warmly about.

Chat AI ships an update every 10 days, ChatGPT weekly. The most recent releases landed on September 22, 2026 and September 27, 2026 respectively.
