# GPT.Zero vs Originality.ai

The clearest difference is rating: GPT.Zero at 4.5 against Originality.ai's 1.0. GPT.Zero also leads on ratings volume (74 vs 1). Originality.ai's advantage is monetization model (freemium vs subscription). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. GPT.Zero sells 3 in-app purchases, starting at $6.99 per 7 days 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.

GPT.Zero holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: GPT.Zero has 74 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 0% and 0% positive.
