Publons collects information about peer reviews and builds public reviewer profiles for participating reviewers. A Publons profile shows a researcher’s verified review history across all journals, without revealing any sensitive information about the manuscript.

Reviews are added to Publons in two ways, depending on whether or not the reviewer’s journal is an official partner of Publons.

Reviews performed for partnered journals are added automatically via the journal's peer-review submission system.

For other journals, reviewers add the information themselves -- usually by forwarding the “Thank you for reviewing” emails to as proof. Publons verifies the emails and adds the review records to the reviewer’s profile.
