Open preprint reviews.
For all researchers.

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

Review a preprint

For underserved researchers

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.

A better way

Making science and scholarship more equitable, transparent, and collaborative.
