Media files stay local; diagnostics are separate. Your media file is processed in your browser and is not uploaded or sent to an AI service. If enabled, anonymous diagnostics may be sent, but they do not contain file contents.

Processing Architecture & Calibration

All media streams are isolated locally inside your device using hardware-accelerated WebAssembly (WASM) and WebCodecs. Zero bytes of audio or video content are ever transmitted to external cloud servers.

How It Works

  1. Drop your audio or video file directly into the browser dropzone.
  2. The client-side engine executes local inference or bit-exact extraction without upload delays.
  3. Audition the 15-second realtime A/B comparison with the Dry/Wet slider.
  4. Export your pristine clean master file with 100% original video track preservation.

オンデバイスAI切り抜きはサーバー送信なしでどのように動作しますか？
Drop & Clean はWebAssemblyおよびWebGPUを通じて高精度な視覚認識ニューラルネットワークをブラウザ内で直接実行します。被写体抽出とAlphaマスクは100%お使いの端末上で計算されます。
透過PNGや純白背景画像として書き出しできますか？
はい。滑らかなエッジを持つ透過PNGの出力や、公的書類・EC基準の純白背景への変換、微細な修正ブラシツールに対応しています。
プライベートな写真や商品画像の安全性は確保されていますか？
画像データはブラウザのメモリ内のみに保持され、外部サーバーへのアップロードや保存は一切行われません。完全オフラインで安全に利用できます。
