Well, if you can't paraphrase the text yourself, you can do it with the help of an assistant with artificial intelligence, which will allow you to change the text so as not to lose its meaning, uniqueness, but at the same time improve its quality. Alternatively, you can use this AI paraphraser here https://pr-cy.io/rewrite/.

I need to paraphrase a text very urgently. I have written a big article and some sentences are not quite clear. I would like to change and improve them. Can you tell me how it can be done?
