Reviewing PDFs shouldn't require desktop software or confusing markup tools. Synks renders your PDFs in the browser and lets reviewers click anywhere to leave contextual feedback. Pin comments to specific areas, draw attention to details with freehand annotations, and track changes across versions automatically.

Traditional PDF review workflows involve downloading files, opening them in Adobe Acrobat, adding comments, saving, and emailing back. Synks eliminates every step. Upload your PDF, share a link, and collect visual feedback in minutes.
Every comment is anchored to the exact spot on the page it refers to. No more vague descriptions like 'the text on page 3 near the bottom.' Reviewers click, annotate, and submit — it's that simple.
