# Sum AI vs Ai Summary

The clearest difference is rating: Sum AI at 4.5 against Ai Summary's 3.0. Sum AI also leads on ratings volume (1.7K vs 2) and update cadence (every 3 weeks vs every 3 months). Ai Summary's advantage is ads (none vs shown) and review sentiment (100% vs 76%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Sum AI sells 9 in-app purchases, starting at $4.99 per 7 days and Ai Summary sells 2 in-app purchases, starting at $3.49 per 7 days. Whichever you choose, the download price is not the number that matters.

Sum AI holds the better App Store score, 4.5 against 3.0. That said, the two scores are not equally well evidenced: Sum AI has 1.7K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 76% of Sum AI's written reviews are positive against 100% of Ai Summary's, so the app with the better star average is not the one people write more warmly about.

Sum AI ships an update every 3 weeks, Ai Summary every 3 months. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
