Test 1

When we pasted the 493-word response that ChatGPT provided us with in the first test, Grammarly revealed that 18% of the text was plagiarized. The question asked, What is the difference between WordPress and Shopify?

Test One

Three of the five pages from which the text was extracted specifically discussed Shopify and WordPress.

Test 2

When we asked for information about Argentina in the second test, it took a long time to write a 396-word passage.

Test Two

On the plagiarism scale, Grammarly increased by 14% this time. We did not see any results that were unique for Argentina this time. Grammarly was concerned with presenting a variety of topics on those pages.

Test 3

This time, we gave ChatGPT a 700-word essay to write about the International Space Station. It performed admirably, as Grammarly found only 7% of similarity.

Test Three

Additionally, similar to the second test, not one of the websites was directly related to the International Space Station.

Test 4

ChatGPT performed poorly in the last test. The 26% plagiarism score is blatantly obvious as poor writing.
