Advancing Open Science Through Collaborative Preprint Feedback

The landscape of scholarly communication continues to evolve rapidly as researchers seek faster, more transparent ways to share and evaluate findings. Preprints, which are preliminary versions of research manuscripts posted online before formal journal peer review, play an increasingly central role in this shift. Platforms dedicated to open preprint review address longstanding challenges in traditional peer review, such as delays, limited diversity among reviewers, and lack of recognition for the reviewing process itself.

One prominent initiative in this space is the PREreview platform, which facilitates constructive, open feedback on preprints from a global community. By enabling researchers to post, read, and engage with reviews, the platform supports equity and collaboration in scientific evaluation. Recent activity on the site underscores its growing momentum, with new features and community programs enhancing accessibility for early-career researchers and those from historically underrepresented groups.

Understanding Preprints and the Role of Open Review

A preprint is a version of a scholarly article made publicly available on a server prior to undergoing formal peer review and publication in a journal. Servers such as bioRxiv, medRxiv, arXiv, and others host these documents across disciplines ranging from biology and medicine to physics and social sciences. This practice accelerates the dissemination of research findings, allowing the scientific community to access and build upon new work more quickly than traditional publishing timelines permit.

Traditional peer review, while essential for quality control, often operates behind closed doors with anonymous reviewers and lengthy processes. Open preprint review offers an alternative or complementary approach by making feedback public, attributable, and rapid. Reviewers can provide structured comments on aspects like methodology, originality, clarity, and potential impact, helping authors improve their work while contributing to broader scientific discourse.

PREreview stands out by focusing specifically on this model. It provides tools for individual reviews, collaborative journal club-style discussions, and interactive live review sessions conducted via video calls. The platform integrates with multiple preprint servers and emphasizes inclusivity through multilingual support and targeted training programs.

Key Features Driving Engagement on the Platform

Researchers visiting PREreview.org encounter several core functionalities designed to lower barriers to participation. Users can browse recent preprints, request reviews for specific works, or submit their own structured feedback. Reviews receive unique identifiers and can be linked to ORCID profiles, giving reviewers formal credit for their contributions.

Live Reviews represent an innovative format where groups convene for real-time discussions of a preprint. These sessions produce summaries that authors can use to revise their manuscripts, and participating journals may incorporate the feedback into their workflows. Partnerships, such as with JMIR Publications, demonstrate how the platform extends into overlay journal models and preprint servers.

PREreview Clubs encourage organized groups, often at universities or research institutions, to collectively review preprints. This team-based approach builds skills among participants while generating multiple perspectives on a single work. Training workshops further equip new reviewers with best practices for delivering constructive criticism.

Recent Developments and Platform Highlights

In early 2026, PREreview introduced an experimental matchmaking feature. Users input DOIs or URLs of research objects they have engaged with, and the system suggests relevant preprints aligned with their interests. This tool aims to connect reviewers with content that matches their expertise, increasing the likelihood of high-quality, timely feedback. Community members are encouraged to test the feature and provide input for refinements.

Support for reviewing datasets from repositories like SciELO Data has also expanded, broadening the platform's scope beyond traditional articles. Translation efforts continue to make the interface and workflows available in additional languages, including Brazilian Portuguese, Latin American Spanish, Arabic, and French, promoting wider global participation.

The 2025 PREreview Champions Program selected cohort members to lead local engagement activities. Champions receive training, certification, a modest honorarium, and resources to organize workshops, mentor peers, launch new clubs, or facilitate live reviews within their communities. This initiative directly supports the platform's mission of empowering systematically disadvantaged researchers.

Platform statistics reflect steady growth: over 2,000 PREreviews published, coverage of 33 preprint servers, and nearly 4,500 registered PREreviewers. Recent examples include detailed reviews of preprints on topics such as phylogenomics of fish species, wearable biosensors in pediatric cardiology, and artificial intelligence applications in chemical processes.

Benefits for Researchers and the Broader Scientific Community

Open preprint review through platforms like PREreview accelerates scientific progress by surfacing feedback earlier in the research lifecycle. Authors gain actionable insights to strengthen their manuscripts before journal submission. Reviewers, particularly early-career scientists, develop critical evaluation skills and build professional networks while earning visible credit for their service.

The model promotes diversity by actively recruiting participants from varied geographic, institutional, and demographic backgrounds. Structured templates guide reviewers, reducing intimidation for newcomers. Public reviews also foster accountability and can reveal potential biases or conflicts that anonymous systems might obscure.

For institutions and funders, widespread adoption supports open science principles, potentially improving research reproducibility and public trust. Integration with ORCID ensures contributions are tracked across platforms, aiding career advancement in an era where service activities receive greater recognition.

How Researchers Can Participate and Get Started

Getting involved begins with creating a free account on the platform using an ORCID identifier. From there, users can explore the matchmaking experiment, browse active review requests, or select a preprint from supported servers to review. The review process involves answering guided questions on scientific rigor, novelty, and clarity, followed by optional free-text comments.

Those interested in deeper engagement might join or form a PREreview Club, attend a live review session, or apply for future Champions cohorts. The platform maintains an active Slack community and newsletter for updates on events, new features, and opportunities.

Authors seeking feedback can request reviews directly through the site or compatible preprint servers, increasing visibility for their work among engaged reviewers.

Challenges and Ongoing Evolution in Open Peer Review

While promising, open preprint review faces hurdles including variable reviewer participation rates, ensuring review quality, and integrating outputs with traditional journal processes. Some researchers remain hesitant due to concerns about public criticism or the time commitment involved.

PREreview addresses these through community support, training resources, and iterative platform improvements based on user feedback. Continued expansion of supported servers, enhanced notification systems, and partnerships with journals help bridge gaps between preprint and formal publication stages.

Broader ecosystem developments, such as policy changes from funders encouraging open practices and growing acceptance of preprints in hiring and promotion decisions, create a favorable environment for these tools.

Looking Ahead: The Future of Preprint Evaluation

As the volume of preprints grows, platforms facilitating structured, open feedback will become indispensable. PREreview's strategic focus on localization, matchmaking, and community leadership positions it to scale impact. Future enhancements may include advanced recommendation algorithms, expanded dataset support, and deeper integrations with scholarly infrastructure.

The emphasis on equity ensures that benefits extend beyond well-resourced institutions, contributing to a more inclusive global research enterprise. Researchers, administrators, and policymakers alike benefit from monitoring these developments as they shape the next generation of scholarly communication.

For those in academia seeking to stay informed on evolving publishing practices, resources on career development in higher education provide additional context on navigating open science landscapes.
