# AI Chat vs Scan AI

The clearest difference is update cadence: Scan AI at every 3 weeks against AI Chat's every 4 months. Scan AI also leads on review sentiment (98% vs 76%) and iOS requirement (12.4 vs 14.0). AI Chat's advantage is ratings volume (1.3K vs 24). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. AI Chat sells 3 in-app purchases, starting at $6.99 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: AI Chat has 1.3K ratings behind it against 24, so its average is the more settled of the two. Written reviews point the same way: 76% of AI Chat's written reviews are positive against 98% of Scan AI's.

AI Chat ships an update every 4 months, Scan AI every 3 weeks. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
