Description
Plinth turns 3D client review into one clean loop: import a USDZ model, pin feedback directly on the geometry, send your client a review link, and capture a clear decision — Approved or Request Changes — with a PDF sign-off record.
Built for product and industrial designers, furniture and hardware makers, and anyone who presents 3D concepts to clients and needs a real decision back.
WHY PLINTH
Comments live ON the model — pins are anchored to the 3D geometry, not to a screenshot or a video frame
A formal decision step — your client taps Approved or Request Changes (with an optional note), and that decision comes back to your dashboard
A sign-off record — export a clean review PDF with the decision, comments, and signature lines
No client account needed — clients open your review link in the free Plinth app and respond; they never pay
HOW IT WORKS
1. Import a USDZ model from Files
2. Orbit, inspect, and pin review notes on the model
3. Publish a review link and send it to your client
4. They review and decide — you pull the decision back, status updates, done
5. Export the PDF sign-off for your records
WHAT'S IN THE FREE VERSION
Import and present your model, pin comments, and complete one full client-approval loop — free. Plinth Pro unlocks unlimited projects, unlimited comments, unlimited review links, and clean unbranded PDFs.
HONEST SCOPE (v1)
Plinth is early software, built in the open. Today it's iPhone/iPad with USDZ import; review links open in the Plinth app. Browser-based review, more file formats (glTF/OBJ/STEP), Mac, and spatial review are on the roadmap — tell us what you need first.
