Paper all-in-one assistant: select text on any page and rewrite it inline to paraphrase, reduce similarity, or lower AI-like wording. Free to try, no login. Similarity rewrite, AI-tone rewrite, helpers, and AIGC detection use separate daily quotas. Also AIGC detection (model rate and a short note; not an official report), translate, explain, summarize, and a Word trial. Extra modes: stronger and English rewrite. Night mode can follow the system. Please read the result before submitting.
