Could you build this?
Partial The UI and 3D typography using Three.js are accessible, but orchestrating multiple on-device WebAssembly/WebGPU ML pipelines (background removal, OCR, video cutting) smoothly in-browser without crashing memory is technically challenging.
What it would actually take: Requires compiling modern CV models (e.g. RMBG, Whisper/PaddleOCR) to ONNX Runtime Web or TensorFlow.js using WebGPU/Wasm backends, combined with an in-browser video processing pipeline (using webcodecs or FFmpeg.wasm) and Three.js for 3D typography rendering. The hard part is client-side memory management, hardware acceleration fallbacks across varied user GPUs, and maintaining acceptable frame rates and inference latency entirely client-side.
