# nanoGPT vs Core AI

The clearest difference is in-app purchases: Core AI at none against nanoGPT's 1. Core AI also leads on update cadence (every 2 days vs every 12 months) and ratings volume (18 vs 3). nanoGPT's advantage is rating (5.0 vs 4.6). On price, ads and iOS requirement there is nothing between them.

Both are free to download. nanoGPT sells 1 one-off in-app purchase. Core AI asks for nothing beyond the download.

nanoGPT holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Core AI has 18 ratings behind it against 3, so its average is the more settled of the two.

nanoGPT ships an update every 12 months, Core AI every 2 days. Both last shipped on November 4, 2026.
