Why can’t I see the theme or subtitle preview?

Updated over 2 months ago

Some of Storykit’s preview features relies on a technology called WebGPU. This is a new web standard that’s still under development, and not all browsers support it yet.

Do you get this error?

Some of Storykit’s preview features relies on a technology called WebGPU. This is a new web standard that’s still under development, and not all browsers support it yet.

You can check if your browser supports WebGPU here:

If your browser doesn’t support WebGPU, try opening Storykit in a compatible browser (for example, the latest version of Chrome, Edge, or Safari).
If you’re using a compatible browser and still can’t see the preview, the issue might be your device. Some computers, laptops, or smartphones don’t have the necessary hardware to run WebGPU.
