Knowledge/Memory between different ChatGPT Sessions is not stored. But you can very easily ask "Please summarize this:" Then, pasting in however many Paragraphs the chat UI allows. Repeat until fully summarized. Other useful questions to try after each sub-summary are: "Were there any points of interest outside of this summary?" "Could you give me more detail on what the article said about X, Y, Z?" I once used chatGPT to summarize a 30,000 word article, and after moving chatGPT's summaries to a .txt, it had been reduced to about 3,000 words. The summaries and points of interest also gave me great bits to search for in the full article.
