Comments let you explain a change, ask a question or flag a problem without altering the document itself. Choose Sticky note, click where it belongs and type. The note appears as a small icon; hovering or clicking shows the text. Pick from five colors to tell reviewers apart.
On download, notes are written as standard PDF text annotations, so Adobe Acrobat, Apple Preview, Chrome, Edge and Firefox all list them in their comments panel and can reply to them. Your document never leaves your device.
