# Second Brain vs AI Chat

The clearest difference is ads: Second Brain at none against AI Chat's shown. Second Brain also leads on rating (4.8 vs 4.3). AI Chat's advantage is update cadence (every 9 days vs every 4 weeks) and device support (3 vs 1). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Second Brain sells 3 in-app purchases, starting at $5.99 per 7 days and AI Chat sells 4 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Second Brain holds the better App Store score, 4.8 against 4.3. Both are backed by a comparable volume of ratings — 61 and 106 respectively.

Second Brain ships an update every 4 weeks, AI Chat every 9 days. Both last shipped on November 3, 2026.
