How Our Peer Review Tool Works

1

Upload Manuscript

PDF or Word. Journal articles, dissertations, theses, conference papers, preprints, and more.

2

Reviewer Panel Analysis

Up to 7 specialist reviewers examine your work in parallel: methodology, statistics, domain relevance, argumentation, and more. See all reviewer capabilities.

3

Editor-Style Decision Summary

Receive a consolidated decision letter with prioritized major vs. minor revision guidance. Delivered in minutes.

Your AI Paper Reviewer Panel

Each reviewer examines your manuscript from a different angle. Here is exactly what they catch.

Statistical Methods

Flags underpowered sample sizes, inappropriate tests, overstated effect sizes, and missing model assumptions. Provides corrective code in R, Python, or Stata.

Systematic Reviewer

Identifies unclear study design, missing inclusion criteria, confounding not addressed, and reproducibility gaps. Checks CONSORT, PRISMA, and STROBE compliance.

Domain Expert

Evaluates literature gaps, outdated citations, novelty assessment, and missed competing findings in your specific field.

Results Accuracy

Detects tables inconsistent with narrative text, incomplete outcome reporting, calculation errors, and data that doesn't add up.

Adversarial Skeptic

Highlights unsupported conclusions, causal claims from observational data, logical gaps between sections, and missing limitations.

Pragmatic Reviewer

Assesses clarity, practical significance, and accessibility for broader audiences. Identifies areas where writing could be clearer and findings more actionable.

Scientific & Technical Writer

Evaluates clarity, grammar, terminology consistency, journal style adherence, and scientific communication quality.

Editor-in-Chief

Consolidates all feedback into a prioritized decision letter with major vs. minor revision guidance and overall publication readiness assessment.

Example feedback from real reviews:

Your use of a paired t-test assumes normality. Consider Wilcoxon signed-rank given your sample size of n=12. Here is corrective R code...

Table 3 reports n=245 but the sum of subgroup ns is 243. This discrepancy should be resolved before submission.

Three recent RCTs (2023–2024) directly contradict your stated hypothesis. These should be addressed in your Discussion.

Sample output:

“The methods section lacks sufficient detail to determine whether the analytical approach appropriately addresses potential confounding. I also note the conspicuous absence of any reference to my 2019 paper on this exact topic.”

AI Peer Review Tested Against Real Journal Reviews

In a preliminary analysis of 5 manuscripts published in The BMJ (2021–2023), PeerGenius reviews were compared against journal peer reviews using a 10-dimensional scoring framework.

Complementarity

This peer review tool complements traditional peer review. It does not replace it. Our reviewers caught issues that journal reviewers missed, and vice versa.

Why PeerGenius Exists

Many manuscripts encounter reviewer criticism not because the research lacks value, but because methodological, statistical, or analytical issues weren't caught early enough. I built PeerGenius to change that.

I created this tool for students, researchers, and faculty who want to submit stronger manuscripts with confidence. As a mathematical statistician, frequent journal reviewer, and researcher with 70+ publications in journals including The Lancet HIV, MMWR, Epidemiology, AIDS, and JAIDS, I've spent my career identifying the kinds of analytical weaknesses that slow down or derail the publication process. PeerGenius puts that expertise to work for you.

But I didn't just want a peer review tool that flags problems. I wanted something that actually helps you fix them. PeerGenius simulates the perspectives of multiple specialist reviewers, consolidates feedback into an editor-style summary, and pairs every identified issue with a concrete solution, so you spend less time guessing what to revise and more time doing it. And because I believe the best feedback teaches, each solution includes an explanation of why it's the right approach, giving you something useful to carry into your next manuscript.

I also built this tool with a different kind of researcher in mind. Imposter syndrome is real, and it hits hardest for students, newly minted PhDs, and anyone who has ever wondered whether they truly belong in their field. PeerGenius provides honest, judgment-free feedback in a space where there is no audience and nothing to prove. You can stress-test your work, find the gaps, and walk into your next advisor meeting or journal submission with a clearer understanding of where you stand and how to improve.

For graduate students especially, this tool can be a game changer. Running your dissertation, thesis, or research paper through PeerGenius as part of your manuscript review before submission means you already know the weak points and have thought through solutions. That kind of preparation leads to more focused, productive conversations and builds the kind of confidence that comes from actually knowing your work. It can also be an invaluable resource when preparing for your thesis or dissertation defense. Because the agents simulate reviewers coming from varied perspectives and disciplines, the feedback you receive helps you anticipate the kinds of questions that might otherwise seem like they came out of nowhere. Walking into your defense having already wrestled with those questions is a very different experience than encountering them for the first time in the room.

PeerGenius can also be used to assess papers that have already been published. Running existing studies through the tool is a useful way to identify methodological limitations, gaps in the evidence, and areas where the research could be extended. For students trying to carve out their own independent research niche, this can be a practical starting point for figuring out where the field has been, where it falls short, and where there is still meaningful work to be done.

Beyond improving your own work, PeerGenius can also help students and early-career researchers learn how to construct meaningful peer reviews. Understanding what good critical feedback looks like, and why it matters, is a skill that takes years to develop. This tool gives you a front-row seat to that process, and in doing so, helps prepare the next generation of researchers to give back to the scientific community the same way those before them did.

PeerGenius also assesses technical writing and provides suggestions to help sharpen clarity and precision, so the final product reflects the quality of the research behind it.

Looking further ahead, one of my goals for PeerGenius is that it can one day play a role in the actual peer review process for journals. I am not advocating for replacing human reviewers. But I do believe that a tool like this, paired with a human in the loop, could meaningfully speed up the review process, raise the quality of the feedback being returned to authors, and reduce the burden on scientific professionals who are already stretched thin by the ever increasing volume of manuscripts that need to be reviewed. The peer review system depends on the goodwill of researchers giving their time, and anything that makes that process more efficient and less exhausting is worth pursuing.

The goal is simple: a higher quality submission that spends less time in revision and more time in print.

Best,
