Verdict
The clearest difference is ads: Second Brain at none against Chat AI's shown. Second Brain also leads on update cadence (every 4 weeks vs every 19 months) and ratings volume (61 vs 1). Chat AI's advantage is rating (5.0 vs 4.8) and device support (3 vs 1). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Second Brain sells 3 in-app purchases, starting at $5.99 per 7 days and Chat AI sells 4 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Chat AI holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Second Brain has 61 ratings behind it against 1, so its average is the more settled of the two.
Second Brain ships an update every 4 weeks, Chat AI every 19 months. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
