Matchmaking experiment

Help us improve how we match researchers to preprints based on research interests

Take the survey

Open preprint reviews. For all researchers.

Provide and receive constructive feedback on preprints from an international community of your peers.

Peer review training

Interactive workshops for organizations and institutions looking to help their members hone their skills as reviewers.

Read about our training workshops

Live Reviews

We run collaborative, interactive preprint review calls as an alternative approach to traditional peer review.

PREreview Clubs

Start or join one of our preprint review groups, where members work together to provide timely, constructive feedback.

See our many PREreview Clubs

PREreview is celebrating Peer Review Week 2026 with a global Review-a-thon, where Clubs review together preprints and datasets in any field or language. The goal is to showcase the transformative power of human, collaborative peer review in the research evaluation culture.

For underserved researchers, there’s a better way

We support and empower diverse and historically excluded communities of researchers (particularly those at early stages of their career) to find a voice, train, and engage in peer review.
