For peer reviewers, Publons provides a way to get recognition for their contributions (without breaking reviewer anonymity) in a format they can include in promotion and funding applications.
Add the pre or post-publication reviews you've performed to a verified, publisher-independent profile in order to demonstrate your experience and expertise. You control how each review is displayed on your profile (blind, open, or published).
For editors, Publons allows you to track the individual manuscripts you handled as an editor and the reviewers you employed in vetting them.
With Publons, you can record the details of papers edited for any journal -- in one place. Likewise, you can keep track of all reviewers you've worked with independent of the journals they reviewed for.
Your profile can then be used to create verified reports of review and editing contributions which can in turn be used to supplement promotion or funding applications.
