# GPTZero vs Originality.ai

The clearest difference is review sentiment: GPTZero at 70% against Originality.ai's 0%. GPTZero also leads on rating (4.3 vs 1.0) and ratings volume (135 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. GPTZero sells 5 in-app purchases, starting at $7.99 per month and Originality.ai sells 3 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
