Xenmark

Xenmark is a browser-based PDF drawing review platform for engineering, construction, architecture, and other technical teams. It keeps drawing annotations, structured comments, replies, statuses, and revisions together in one shared project workspace instead of scattering feedback across marked-up PDFs, emails, spreadsheets, and chat.

Engineers can upload a drawing, invite clients or other reviewers, and collect feedback directly on the drawing. Reviewers and collaborators are always free, while the project owner manages the project and subscription. Reviews can also be exported as structured PDF and Excel comment registers.

What problem it solves

Drawing feedback often arrives through marked-up PDFs, emails, spreadsheets, chat, and phone calls. Xenmark gives engineering and construction teams one shared place to collect comments directly on the drawing, track what is still open, manage revisions, and avoid manually reconciling several sources of feedback.
