How Cutova helps

Models: BiRefNet_lite (MIT) on WebGPU and ormbg (Apache-2.0) on WebAssembly. Pages are cross-origin isolated for multithreaded WebAssembly, and a strict Content Security Policy prevents any upload. A public API is planned but not available yet.

Frequently asked questions

Is there an API?

Not yet. It is planned; today Cutova is a web app.

Which browsers are supported?

Recent Chrome, Edge, Firefox and Safari. WebGPU is used only when the graphics card supports what the model needs.
