Try Litrevu FreeAnara (formerly Unriddle) is a research workspace for finding, reading and asking questions of papers. Litrevu is made for what a literature review asks of the papers you chose: comparing them, checking your own claims against them, and keeping your references straight.

Paste a paragraph you wrote and see which of its claims your papers back, with the passages that decide it.

Many university AI policies allow AI as a study aid, for reading, searching and summarising your sources, often with a declaration. That is what Litrevu is built for. Litrevu can also draft cited text, but many universities do not allow AI-written text in submitted work, even after you edit it. Check your institution's policy, write your own text, and declare how you used Litrevu.
