Can I personalize a copy for each reviewer?

Yes — personalization is the whole idea. You give the tool a list of reviewers, and it generates one copy per reviewer, stamped with that reviewer's name. So instead of sending the same anonymous PDF to fifty people, each person gets a copy that's visibly theirs.

Alongside the files you get a manifest mapping each reviewer to their file and a checksum, so a surfaced copy can be traced back. See Where does the reviewer's name appear? and What is the traceability manifest?
