What does 'privacy-first' mean for image tools?

The tool runs entirely in your browser. Your photos are never uploaded to a server, processed on a third-party GPU, or stored after the tab closes. The only network traffic is the AI model download.

Are browser-based AI tools really free?

Yes. Because the compute runs on your device, there is no server cost to pass on. Open-source tools can be free and unlimited forever.

Do I need a powerful computer to run local AI?

No. Modern browsers fall back from WebGPU to WASM CPU. Even a 5-year-old laptop handles background removal in 5-10 seconds.
