Xenmark is a browser-based PDF drawing review platform for engineering and construction teams. Upload technical drawings, add annotations and structured comments, track comment status, manage revisions, collaborate with internal and external reviewers, and export structured PDF and Excel comment registers.

Xenmark is designed to keep drawing feedback in one shared project instead of exchanging multiple marked-up PDF files by email.

Only the project owner ever needs a subscription. Reviewers and collaborators are always free, with no additional per-reviewer cost. The Free plan includes one active project, while paid plans increase the number of active projects available.

Questions & Answers

As answered by people managing Code Poster and Xenmark.app.

What makes your product unique?

Xenmark.app's answer:

Only the project owner pays. Reviewers and collaborators join free, with no per-seat cost. Everything runs in the browser, so participants do not need specialist software installed to review and mark up drawings.

Why should a person choose your product over its competitors?

Xenmark.app's answer:

General PDF tools handle annotation but not structured review workflows. Broader document management platforms can handle those workflows but often price access by participant. Xenmark sits between them: spatial pins, threaded replies, comment statuses, revision handling, and exportable comment registers โ€” with pricing based on the project owner rather than each reviewer.

How would you describe the primary audience of your product?

Xenmark.app's answer:

Engineering, construction, and architecture teams that circulate drawings for comment across company lines โ€” client, yard, subcontractor, consultant. Most useful where review feedback must be traceable afterwards, not just marked up once.

What's the story behind your product?

Xenmark.app's answer:

Drawing feedback arrives scattered โ€” marked-up PDFs, email threads, spreadsheets, chat. Someone then reconciles it by hand and works out what is still open. Xenmark was built to collapse that step: one workspace where comments, replies, statuses, and revisions stay attached to the drawing.

Which are the primary technologies used for building your product?

Xenmark.app's answer:

Browser-based application built with React and Vite. Supabase provides database, authentication, and role-based permissions. Cloudflare R2 handles drawing and attachment storage; Stripe handles billing. PDF rendering and annotation run client-side.
