# DetectGPT vs GPTZero

The clearest difference is rating: DetectGPT at 4.8 against GPTZero's 4.3. DetectGPT also leads on review sentiment (80% vs 70%). GPTZero's advantage is ratings volume (135 vs 16) and update cadence (every 8 days vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. DetectGPT sells 9 in-app purchases, starting at $5.99 per 7 days and GPTZero sells 5 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

DetectGPT holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: GPTZero has 135 ratings behind it against 16, so its average is the more settled of the two. Written reviews point the same way: 80% of DetectGPT's written reviews are positive against 70% of GPTZero's.

DetectGPT ships an update every 2 weeks, GPTZero every 8 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
