# MS vs AI

The clearest difference is price: AI at Free against MS's $9.99. AI also leads on rating (5.0 vs 4.0) and update cadence (every 2 weeks vs every 56 months). MS's advantage is in-app purchases (none vs 4). On ratings volume, ads, device support and iOS requirement there is nothing between them.

AI is free to download; MS costs $9.99 up front. AI sells 4 in-app purchases, starting at $9.99 per 7 days. MS asks for nothing beyond the download.

AI holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 3 and 8 respectively.

MS ships an update every 56 months, AI every 2 weeks. The most recent releases landed on August 18, 2026 and October 9, 2026 respectively.
