Show HN: A segmentation model client-side via WASM – free background removal

[shivaodin]

Built a background removal tool that loads a ~40MB segmentation model into the browser via WASM/WebGPU and runs inference client-side.

No upload step, no API call, no queue. Drop an image, get the result in 2-3 seconds. No per-image charges because there's no server doing the work.

The same cached model powers 6 derivative tools — background changer, passport photo maker, product photo whitener, portrait blur, sticker maker — each just different post-processing on the same mask output.
