AXO Archkit
A multi-mode browser-based workspace for architectural PDFs. Tile and print large drawings (Poster, Tapestry), markup and annotate (Markup), build issue schedules and sheet binders (Schedule, Sheets), author project briefs (Brief), compare revisions (Revise), present drawing sets (Present), and mark student work against rubrics (Quill). Local-only — your files never leave the browser.
