# AI Chat vs Illustrate GPT

The clearest difference is ads: Illustrate GPT at none against AI Chat's shown. Illustrate GPT also leads on rating (5.0 vs 4.7). AI Chat's advantage is ratings volume (1.7K vs 1) and update cadence (every 3 weeks vs every 3 months). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. AI Chat sells 1 in-app purchase, starting at $2.99 per month and Illustrate GPT sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Illustrate GPT holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: AI Chat has 1.7K ratings behind it against 1, so its average is the more settled of the two.

AI Chat ships an update every 3 weeks, Illustrate GPT every 3 months. The most recent releases landed on October 30, 2026 and October 17, 2026 respectively.
