Xenmark is a browser-based platform for reviewing technical PDF drawings and managing comments across project teams.
Upload engineering drawings, place comment pins directly on PDFs, and discuss issues through threaded conversations. When a revised drawing is uploaded, existing comments can be carried forward, preserving review history across revisions.
Designed for engineers, consultants, contractors, and project owners, Xenmark replaces scattered emails and manual drawing markups with a centralized review workflow.
Export annotated PDFs and Excel comment logs for documentation and follow-up. The free plan includes the core review functionality, while paid plans provide additional project capacity and customization.
Technical drawing reviews often rely on emails, spreadsheets, and manually annotated PDFs. Comments become difficult to track, especially when drawings are revised multiple times. We built Xenmark to simplify that process. Reviewers can comment directly on drawings, discuss issues in context, and retain comments across revisions. Our goal is to make structured drawing reviews accessible to teams of any size without requiring expensive enterprise software.
