How it works
Three steps. Under 60 seconds.
Upload a GLB
Drag and drop your 3D model. We encrypt it and generate a shareable link.
Share the link
Send it to anyone — supplier, client, teammate. They open it on any device. No account needed.
Get pinned feedback
Reviewer taps the model surface and drops a comment pinned to exact 3D coordinates.

Built for hardware teams
Real workflows, not hypotheticals.
Hardware startups
Get client feedback on enclosure designs without scheduling a call. Share a link, get pinned comments overnight.
Contract manufacturers
Review DFM issues with your Shenzhen supplier across time zones. They pin exactly which face needs a radius change.
Distributed design teams
Async design reviews that capture exact viewpoints. No more "which edge do you mean?" on a video call.
Your designs stay private
Files encrypted at rest (AES-256). Signed URLs expire in 1 hour. Delete your project anytime — model and all comments permanently removed.
