Common questions.

Buyers reviewing them. Xenmark is built for the side that receives drawings — owners, owner reps, building managers, asset operators, technical consultants. The engineering firm joins free as a Participant if you want them to address and close out comments.

No. Xenmark is focused on PDF drawing review. Engineering firms work in their CAD master files; reviewers work in PDFs. Xenmark is the structured surface in between — where the comments and replies live.

Yes. Xenmark has Length, Polylength, Perimeter, and Area measurement tools. Set the page scale first — by preset ratio, custom ratio, sheet format, or by calibrating from a distance you already know — then choose whether values show in metres, centimetres, or millimetres. Any calculated value can be overridden with a known dimension. There are also Check, Cross, Attention, Arrow, and Cloud symbols for marking a drawing without writing a comment. Available on all plans.

No. Xenmark is a focused review workflow that produces clean deliverables — comment plan PDF, comment list Excel, full archive bundle on close. It complements your DMS, it doesn't replace it. Store the deliverables wherever you already store project documents.

Anything from a house plan to a ship block, fabrication package, plant layout, or general technical drawing review. If you receive PDF drawings from an engineering firm, Xenmark fits — projects big or small.

No. Xenmark is web-based. Open a browser, sign in, and start reviewing. No desktop client, no plugins, no full BIM suite.

Each drawing slot keeps a revision history. When the engineering firm sends a new revision, you upload it to the same drawing slot. Old comments stay tied to the revision they were made on. New comments live on the new revision. Status workflow tracks "addressed in Rev B" cleanly.

Three: Project Manager, Editor, and Participant. The Project Manager runs the project — that's you. Editors are your team, consultants, and technical reviewers on your side. Participants are typically the engineering firm responding to feedback. Editors and Participants are free.

No. The Project Manager is the only one who needs a plan. Everyone you invite — your team as Editors, your engineering firm as Participants — joins free. The whole review conversation lives in one shared place without anyone else needing to buy anything.

No. Participants can view project content, add replies to comments, and export the register (PDF/Excel), but cannot create comments, add annotations, upload drawings, or change statuses. The role is built for engineering firms and external reviewers who need to participate without changing core project structure.

Yes. Project Managers, Editors, and Participants can all export the comment plan PDF and Excel list for any project they have access to. Export is not restricted to Project Managers.

Yes. Each project is access-controlled. Members only see the projects they have been invited to. No cross-project leakage, no accidentally exposing one client's drawings to another.

Two documents: a comment plan PDF (where each numbered comment is, spatially) and a comment list Excel (what each comment says). Same numbered pins on both. The engineering firm processes them like any other deliverable.

On Plus and Pro, yes — your logo and document control format on both the comment plan PDF and the Excel list. On Free, deliverables are Xenmark-branded. Custom branding is the key upgrade reason for working professionals.

A full archive bundle (.zip) containing every revision's PDF and Excel exports, all comment attachments, the complete activity log, and a README. Stored on your side. PDFs and Excel files readable forever, in any tool. No vendor lock-in.

No — and intentionally so. Xenmark is a review coordination tool, not permanent storage or a document archive. Free projects delete after a 7-day grace period. Plus projects move to read-only archive for 180 days, then delete (Pro: 365 days), with email reminders before deletion. You walk away with the archive bundle on your own storage. That's the durable record.

No. Xenmark is a review coordination tool for structured comment workflows on PDF drawings. It is not intended as permanent storage, certified document control, a legal archive, or a safety-critical record system. Store the archive bundle — which you download when a project closes — in your own DMS or storage. That's the durable record. Xenmark steps out of the way.

Every action that happened during the review — who created the project, who joined, who uploaded each revision, who created each comment, every status change, every reply, every deletion — with timestamps and attribution. Audit-grade timeline for owner reps facing potential disputes months later.

Yes, and it's free on every plan. Build against your own Xenmark data — what's new in your inbox, which projects you're on, what's still open on a revision — and every item comes back with a link straight into Xenmark. It's read-only, so nothing you connect to it can create a comment, change a status or touch a drawing, and it never hands back an email address, a file or a billing detail. Pair it with a Personal API token you create under Account & Security → Connected apps — no password ever leaves Xenmark, and you can revoke the token any time. Runnable requests live on Postman; the full specification is on GitHub.

Yes. Point your AI assistant at Xenmark and just ask — “Anything new for me?”, “What's still open on Rev B of drawing 1001-300?”, “What did Greta reply on comment #7?” It reads your reviews and answers in plain language, with a link into Xenmark on every item it mentions, so you go straight to the comment instead of hunting for it. It works with any assistant that speaks the Model Context Protocol, runs on your own machine, and can only read — it cannot change a comment, a status or a drawing. Setup is one line, npx -y xenmark-mcp, plus a Personal API token. Free on every plan, and open source on GitHub.

Three plans: Free (€0 — 1 project, 3 drawings, 3 revisions, 5 members, 250 MB attachment storage per project, Xenmark-branded exports), Plus (€14.99/mo — 3 projects, 5 drawings, 5 revisions, 10 members, 500 MB attachment storage per project, custom branded exports, 10 archive slots), and Pro (€59.99/mo — 15 projects, 20 drawings, 20 revisions, 30 members, 2 GB attachment storage per project, custom branded exports, 50 archive slots). See the pricing page for full details.

Yes. The Free plan gives you one complete review at a time — one active project, three drawings per project, three revisions per drawing, and up to five project members. Deliverables are Xenmark-branded. Start at my.xenmark.app.

Billing is handled through the Xenmark app. The marketing page is static and does not process payments or store billing details.

No. Xenmark is intended for ordinary professional PDF drawing review coordination. Users should not upload classified, highly sensitive, safety-critical, legally critical, high-value, or regulated content that requires certified document control or compliance with regulatory archiving standards. If your project requires certified document control or regulated archiving, a dedicated compliance system is more appropriate.

No. Login and signup are handled by the actual Xenmark app at my.xenmark.app. This page exists to introduce the product — authentication and billing live where they belong.

No drawing data lives on the marketing page. All projects, drawings, comments, and deliverables live inside the authenticated Xenmark app — until you close the project, download the archive bundle, and walk away.

Use the contact page to reach out — we'll get back to you. Once you have an account, support is also available from inside the Xenmark app.
