See the review happen live

Live presence shows who is reviewing and which document they are reading. Comments and replies sync as they arrive, while an activity log keeps a record of the review.

Join with a link

There is no account to create. Reviewers join with a workspace link and receive a friendly animal identity they can customize. Protected workspaces also require a password shared separately from the link.

A fresh pair of eyes starts here.
