Saved my thesis draft with solid plagiarism checking and rewriting.
Flagged a few proper citations as AI content by mistake.
Very handy for campus work.
Free checks are too limited before forcing an upgrade.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Run similarity checks against a large comparison corpus, with several versions of checking available for different stages of a paper.
Detect how much of a document reads as AI-generated, so you can address the AIGC rate before submission.
Rewrite content to bring down both the similarity rate and the AIGC rate while aiming to preserve original formatting and meaning.
Generate drafts of literature reviews, proposals, journal articles and course papers with references and structure.
Formatting, PPT creation and research utilities support the wider thesis workflow from draft to defence.
PaperRed (paperred.com) is a China-focused academic toolkit built around the four stages students actually go through: write, check, reduce, and defend. It brings plagiarism checking, AIGC detection, similarity reduction and AI writing into a single platform, so a paper does not have to move between separate services at each step.
The writing side targets the standard campus deliverables — literature reviews, opening proposals, course papers, thesis drafts and journal articles — with support for multiple disciplines and document types. The checking side offers several versions of similarity detection plus AIGC detection, and the site highlights a free daily quota for basic checks while reserving more thorough, final-version checks for paid tiers. The reduction side uses AI rewriting to lower both the similarity rate and the AI-generated content rate, with the stated aim of keeping the original formatting and meaning intact.
Beyond the core four steps, PaperRed bundles formatting and typesetting, PPT creation and research tools, and supports computer, mobile mini-program and WeChat access. The platform is operated by Shandong Zhisheng Information Technology Co. and markets itself on accuracy, a large comparison corpus and data security for uploaded documents.
Check a thesis before submission and understand both the similarity rate and the AIGC rate.
Generate structured drafts of literature reviews and opening proposals as a starting point for revision.
Rewrite passages to lower similarity while keeping the formatting and meaning of the original text.
Use the formatting, PPT and research utilities to prepare defence materials and presentation decks.
