Peer review training

Interactive workshops for organisations 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.

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.
