# Rayyan vs AI Detector

The clearest difference is review sentiment: Rayyan at 37% against AI Detector's 0%. Rayyan also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 15 months). AI Detector's advantage is rating (4.1 vs 3.8) and iOS requirement (13.0 vs 15.1). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Rayyan sells 13 in-app purchases, starting at $9.99 per month and AI Detector sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AI Detector holds the better App Store score, 4.1 against 3.8. Both are backed by a comparable volume of ratings — 23 and 22 respectively. Written reviews complicate that: 37% of Rayyan's written reviews are positive against 0% of AI Detector's, so the app with the better star average is not the one people write more warmly about.

Rayyan ships an update every 5 weeks, AI Detector every 15 months. The most recent releases landed on September 25, 2026 and September 26, 2026 respectively.
