# IsI Browser vs AI Browser

The clearest difference is review sentiment: IsI Browser at 100% against AI Browser's 0%. IsI Browser also leads on in-app purchases (none vs 1) and iOS requirement (11.0 vs 15.6). AI Browser's advantage is rating (4.5 vs 3.5) and ratings volume (11 vs 2). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. AI Browser sells 1 in-app purchase, starting at $4.99 per month. IsI Browser asks for nothing beyond the download.

AI Browser holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: AI Browser has 11 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of IsI Browser's written reviews are positive against 0% of AI Browser's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on June 1, 2026 and August 6, 2026 respectively.
