# Chat AI vs Scan AI

The clearest difference is ratings volume: Chat AI at 1.5K against Scan AI's 24. Chat AI also leads on update cadence (every 2 weeks vs every 3 weeks). Scan AI's advantage is review sentiment (98% vs 89%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Chat AI sells 5 in-app purchases, starting at $4.99 per 7 days and Scan AI sells 4 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Scan AI holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Chat AI has 1.5K ratings behind it against 24, so its average is the more settled of the two. Written reviews point the same way: 89% of Chat AI's written reviews are positive against 98% of Scan AI's.

Chat AI ships an update every 2 weeks, Scan AI every 3 weeks. Both last shipped on November 7, 2026.
