The difference between the 4 tools was not the greatest , there were some similarities of course but also there was some differences. For the task I got an article and I asked chatgpt, Perplexity.ai , scite and chat pdf to summarize it. For chat it summarized it really well he divided the article into two parts and gave a brief summary in the end; this was so close to what chatPdf did.It also summarized the article into several parts ;however, it was more brief than the one chatgpt did.And chat pdf was more a of a bullet points summary but chatgpt was in the form of a paragraph.However, for Perplexity.ai it was very organized. It made a very beneficial summary where it divided every important point mentioned in the article alone and enhanced what the article said which made me know in details everything important in the article. For the last one, in my opinion, scite was the best choice since it broke the entire article up into bullet points and provided more context than I had requested. For instance, I had written “summarize this article” as the task, but the website took the article, summarized it and even elaborated on the article and started to classify each thing and its categories which is perfect for studying and it even gave references.

I compared the 4 AI tools against google scholar and i found that the AI tools are way more efficient and get the all the information needed to the point; for example, i asked the AI tools what is tennis and the answer was totally to the point i knew almost the basics about tennis as a sport; however, when i asked google scholar “what is tennis?” i kept getting a sub information not direct information so in my opinion the AI tools are way more efficient and save time. But also, google scholar is more reliable. In my opinion we should always rely on the combination between AI tools and google acholar in order to maintain both time efficiency and reliability

In my opinion the most efficient and useful tools were from chatgpt. It has multiple of tools auch as the humanizer which helped me a lot after getting the summarized article to humanize it and be written in a simpler form asif there was a human who wrote it.And also there is an option that helps in correcting the grammar which is bery useful and easy to help enhance any grammatical errors and develop the paragraph’s structure.
