Xenmark was built to solve a problem that keeps appearing across engineering projects: client feedback on PDF drawings arrives scattered. Emails with no version reference, paper printouts mailed back, scans of marked-up PDFs, half-sentences in Teams chats.

Every new format means time spent reconstructing what changed, who said it, and what still needs action. That tedium costs both sides — in extra revision rounds, missed comments, and deadlines that slip from unclear instructions and unnecessary back-and-forth.

Updating a drawing shouldn't be detective work.

Xenmark replaces the scatter with one structured review per project. Everyone invited to the same place, every comment numbered and tracked, a comment plan PDF and Excel list exported when the review is done. The reviewers you invite never pay.

It's free to try.
