OpenRevyu is an expert-review platform for research papers. Upload a PDF and get comprehensive feedback on structure, methodology, results, novelty, and writing quality in minutes. Use the report as a sparring partner, not a verdict — it surfaces issues a careful reviewer might raise so you can address them before submission.
Currently we support PDF files up to 20MB. This includes research papers, conference papers, theses, grant proposals, and preprints.
A typical review takes 2-4 minutes depending on paper length. Parsing takes ~20 seconds, then two review passes (content + language) run in parallel.
Each review includes: overall score (1-10), rubric scores across 6 criteria, strengths with quotes, weaknesses with fix recommendations, detailed comments linked to PDF locations, reproducibility checklist, claim-evidence analysis, abstract/title assessment, improvement roadmap, and an editorial decision.
By default, 2 passes run in parallel: (1) Content Review — covers structure, methodology, results, novelty, claims, figures, and reproducibility, and (2) Language Review — covers grammar, style, and provides sentence rewrites. You can configure which passes to enable in Settings.
Yes. Request multiple reviews on the same paper, then click 'Compare' to see them side-by-side with rubric score differences.
The roadmap is a prioritized list of actions to improve your paper, ranked by impact. Each item includes what to do, the expected benefit, and the effort level (low/medium/high).
Yes. Click 'Download' in the header to get an annotated PDF with all review highlights baked into the document, plus a summary page at the beginning.
OpenRevyu can auto-generate a professional 'Response to Reviewers' letter based on the review comments. Click 'Response Letter' on the review page to generate it, then copy or download as Markdown.
Every review comment includes an exact quote from your paper. When you click the quote, the PDF viewer scrolls to that location and highlights it. This uses a position index built from your PDF at parse time.
Yes. Select text in the PDF viewer to add your own annotations. Hold Alt + drag to select an area. Your annotations appear in the 'Notes' tab.
Quote matching uses fuzzy text search. It may fail if the PDF has non-standard encoding, scanned images instead of text, or if the review paraphrased instead of quoting verbatim.
On a reviewed paper's page, scroll to the bottom and use 'Submit Revision' to upload the revised PDF. The new review will compare against the previous version's feedback.
The comparison view shows score deltas across all rubric criteria, side-by-side summaries, and counts of addressed/partially addressed/not addressed issues.
If you upload an identical PDF as a revision, the system detects it and reuses the previous review without using a credit. You must make actual changes for a new review.
Each review costs 1 credit. Uploading and parsing your paper is always free — you only pay when you request an expert review. Reviews are $10 each, purchased as credits. Credits are refunded automatically if a review fails or if a revision is identical to the previous version.
$10 per review, paid as you go. No subscription. Institutional pricing is available for universities and research groups — see the Pricing page.
No. Credits you purchase stay on your account until you use them.

Use OpenRevyu as a sparring partner, not a verdict. Reports are designed to surface issues a careful reviewer might raise so you can address them before submission — not to replace the editorial decision of a journal or conference.
