Verdict
The clearest difference is rating: Summarizer AI at 3.0 against ChatPDF's 1.0. Summarizer AI also leads on ratings volume (5 vs 1). On price, update cadence, ads and in-app purchases 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. Summarizer AI sells 3 in-app purchases, starting at $6.99 per 7 days and ChatPDF sells 2 in-app purchases, starting at $8.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Summarizer AI holds the better App Store score, 3.0 against 1.0. That said, the two scores are not equally well evidenced: Summarizer AI has 5 ratings behind it against 1, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly monthly. The most recent releases landed on September 9, 2026 and September 11, 2026 respectively.
