Could you build this?
Partial The UI, settings, and overlay are standard desktop work, but low-latency streaming transcription and translation of system audio across Windows and macOS is a hard engineering problem that vibe coding alone won't solve well.
What it would actually take: Capture system audio with WASAPI loopback on Windows and ScreenCaptureKit on macOS, then run a streaming ASR model (such as whisper.cpp or faster-whisper) and a local translation LLM, both quantized and tuned for consumer hardware. The hard parts are chunking and latency tuning, hardware detection and model selection, and code-signing and notarization for distribution. This needs someone comfortable with audio DSP, local inference optimization, and per-OS packaging.
