GTP chat is an online messaging system designed to provide an easy way to communicate with other people, but it is not suitable for writing an essay.
GTP chat lacks the proper formatting required to write an essay. It does not provide for spaces between words, punctuation, or any other form of grammar commonly found in essays.
While it is easy to quickly jot down ideas, the lack of editing and formatting capabilities makes it difficult to properly articulate an essay.
Additionally, GTP chat does not offer any feedback on the content of the essay, so grammar and spelling issues may remain unchecked, rendering a written essay ineffective. Furthermore, GTP chat provides little to no ability to provide properly-formatted and documented sources, making any type of research paper nearly impossible.
Finally, due to the quick, informal atmosphere of GTP chat, participants tend to write more informally and can create a paper with more casual content than is generally accepted in academic writing.
For these reasons, GTP chat is not suitable for writing an essay.
