# Chat AI vs AI 4.0 | Chatbot

The clearest difference is review sentiment: Chat AI at 97% against AI 4.0 | Chatbot's 36%. Chat AI also leads on monetization model (free with in-app purchases vs subscription) and iOS requirement (13.0 vs 15). AI 4.0 | Chatbot's advantage is rating (4.6 vs 4.2) and ratings volume (130 vs 12). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Chat AI sells 3 in-app purchases, starting at $9.99 per month and AI 4.0 | Chatbot sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AI 4.0 | Chatbot holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: AI 4.0 | Chatbot has 130 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 97% of Chat AI's written reviews are positive against 36% of AI 4.0 | Chatbot's, so the app with the better star average is not the one people write more warmly about.

Chat AI ships an update fortnightly, AI 4.0 | Chatbot every 10 days. Both last shipped on November 3, 2026.
