Hand Tracking
Pinch to grab. Open your palm to rotate the scene. Use both hands to stretch geometry along any axis. No stylus, no mouse — just fingers and joints.

Features
A CAD interface built around you, not the toolbar.
Five ideas removed a thousand buttons. Each one designed to feel like the model is already in your hand.

Voice Editing
Speak intent. Moldr parses commands in real time and applies parametric edits with no menus to navigate.

Live Parametric Editing
Every dimension is bound to the model. Change a number by voice or gesture and the geometry rebuilds instantly.

Under the hood
A tiny event-driven stack.
Every gesture and utterance flows through the same typed bus. Add a new input by publishing to the bus — no rewrites, no glue code.

Typed messages
Every intent is a serialisable event. Reproduce a session by replaying the log.
Pluggable inputs
Add a foot pedal, a MIDI controller, or a webhook — they all speak to the same bus.
Deterministic kernel
The parametric scene is a pure function of the event log. No hidden state.
Zero server round-trips
Everything runs local. Your geometry never leaves the tab unless you export.
How Moldr works
From gesture to geometry, in six beats.
step 01
Raise your hand.
The camera picks up 21 joint landmarks in real time. A glowing skeleton confirms tracking is live.
01
step 02
Pinch.
Thumb meets index. The nearest object highlights amber and is grabbed by the pinch centroid.
02
step 03
Move naturally.
Translate, rotate, and scale with the same hand that already knows how to grip a physical part.
03
step 04
Say what you want.
"Make this 10 mm taller." "Add a chamfer." Voice commands turn into typed parametric edits.
04
step 05
Geometry morphs.
The kernel rebuilds the scene from the event log. History, undo, and replay come for free.
05
step 06
Export.
STL, STEP, or GLTF. Straight from the parametric scene to your slicer or teammate.

Traditional CAD vs. Moldr.
One is a maze of nested menus you learned in a two-week course. The other is your hand.
