Open preprint reviews.
For all researchers.

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

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.
