# WriteGenius vs ChatPDF

The clearest difference is rating: WriteGenius at 5.0 against ChatPDF's 3.5. WriteGenius also leads on update cadence (every 4 days vs every 2 months). ChatPDF's advantage is ratings volume (13 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. WriteGenius sells 6 in-app purchases, starting at $7.99 per month and ChatPDF sells 4 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

WriteGenius holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: ChatPDF has 13 ratings behind it against 1, so its average is the more settled of the two.

WriteGenius ships an update every 4 days, ChatPDF every 2 months. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
