Could you build this?

Partial The notes, quiz, and translation workflow is standard LLM work, but live system-audio capture with low-latency streaming transcription on Windows is technically demanding to make reliable.

What it would actually take: Build a Windows desktop app (e.g., Electron or WPF/.NET) that captures system or microphone audio via WASAPI loopback and streams it to a streaming ASR API (Whisper-streaming, Deepgram, or Azure Speech) with chunking and incremental translation. The hard parts are latency, speaker/segment stitching, and handling diverse lecture audio, which need audio-engineering experience and extensive testing. Post-class notes and quizzes are then ordinary LLM calls.
