Frequently asked questions

Does the AI model upload my photo?

No. The neural model runs completely inside your browser via WebAssembly. Your photos never leave your computer.

Does it work offline?

Yes. After the small model is downloaded on first use, it is cached in your browser and works completely without internet.
