# Prism AI vs HeySage

The clearest difference is rating: HeySage at 5.0 against Prism AI's 4.0. HeySage also leads on review sentiment (100% vs 75%) and iOS requirement (15.0 vs 18.2). Prism AI's advantage is ratings volume (20 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Prism AI sells 2 in-app purchases, starting at $9.99 per month and HeySage sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

HeySage holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Prism AI has 20 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 75% of Prism AI's written reviews are positive against 100% of HeySage's.
