When you open a file here, it is read from your disk into browser memory, processed by JavaScript and WebAssembly running on your own processor, and written straight back out as a download.

The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
