Unlimited Customization
Realize any graphical style with visual programming tool Lens Studio for Mac. Create custom shaders with powerful Material Editor, or choose from the premade Materials Library.

Powerful Interactive Experiences
Start with the Behavior helper script to build interactive experiences without writing code, or use JavaScript to create more complex Lenses.

Transform Anything, Anywhere
With multiple tracking options and features like segmentation and Landmarker tracking, you can create whatever world you dream up.

Add Magic to Your Creations
SnapML allows you to make your Lenses even more intelligent with machine learning. Just plug in an ML model to apply any art style to the camera feed, use custom segmentation masks, attach images to custom detected objects, understand what’s in the scene, and more. Lens Studio is amazing software!
