# Fast AI vs Character Chat AI

The clearest difference is rating: Character Chat AI at 4.1 against Fast AI's 3.0. Character Chat AI also leads on ratings volume (94 vs 3) and update cadence (every 4 days vs every 2 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 Character Chat AI sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Character Chat AI holds the better App Store score, 4.1 against 3.0. That said, the two scores are not equally well evidenced: Character Chat AI has 94 ratings behind it against 3, so its average is the more settled of the two.

Fast AI ships an update every 2 weeks, Character Chat AI every 4 days. The most recent releases landed on October 18, 2026 and October 24, 2026 respectively.
