# ChatPDF vs Skywork

The clearest difference is ads: Skywork at none against ChatPDF's shown. Skywork also leads on review sentiment (34% vs 0%). ChatPDF's advantage is rating (4.6 vs 4.3) and update cadence (every 4 days vs every 10 days). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. ChatPDF sells 2 in-app purchases, starting at $14.99 per month and Skywork sells 29 in-app purchases, starting at $16.99 per month. Whichever you choose, the download price is not the number that matters.

ChatPDF holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 92 and 63 respectively. Written reviews complicate that: 0% of ChatPDF's written reviews are positive against 34% of Skywork's, so the app with the better star average is not the one people write more warmly about.

ChatPDF ships an update every 4 days, Skywork every 10 days. The most recent releases landed on October 16, 2026 and October 22, 2026 respectively.
