Edit real text, mark up, measure, sign and merge PDFs with construction-grade tools — entirely in your browser. Nothing is sent to a server. Ever.
No credit card · Works offline once loaded


Don’t take our word for it — open your browser’s network tab while you work. As you edit, measure and sign, the transfer count stays at zero.
No uploads. Ever.
Every tool runs inside your browser. Contracts, drawings and reports are processed on your machine and nowhere else.
Instant by design
No upload bars, no queues, no server round-trips. A 200-page drawing set opens and scrolls like a native app.
Compliance-friendly
Files never reach our servers, so there is nothing for us to store, leak or be subpoenaed for. We keep only your signature, if you ask.
Open your PDF once — every tool works on it live, side by side. No modules, no re-opening files, no “studio” accounts.
Click any line and change the actual PDF text — not a sticker on top. Fonts and layout stay intact.
Revision clouds, callouts, polygons, freehand pen, stamps, sticky notes — the full redline kit construction teams expect.
Calibrate the scale once, then measure lengths, areas and volumes. Count fixtures with named, shaped markers.
Reorder by drag, rotate, delete, extract and merge pages — all live on the open document, every step undoable.
Draw, type or upload your signature, drop it exactly where it belongs, and keep it on your device for one-click reuse.
Form fields are detected automatically. Fill them inline, then flatten the result so it can never be tampered with.
Turn scans into searchable text and diff two revisions side by side — without ever re-opening the file.
