# Fast AI vs AI Chat

The clearest difference is rating: AI Chat at 4.6 against Fast AI's 3.0. AI Chat also leads on ratings volume (2K vs 3). Fast AI's advantage is update cadence (every 2 weeks vs every 4 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Fast AI sells 1 in-app purchase, starting at $5.99 per 7 days and AI Chat sells 9 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AI Chat holds the better App Store score, 4.6 against 3.0. That said, the two scores are not equally well evidenced: AI Chat has 2K ratings behind it against 3, so its average is the more settled of the two.

Fast AI ships an update every 2 weeks, AI Chat every 4 weeks. Both last shipped on November 3, 2026.
