Could you build this?

Partial The UI and OBS integration are buildable, but live captions need low-latency streaming speech recognition and translation, and the hard part is making that pipeline fast and reliable during a live broadcast.

What it would actually take: Build an OBS plugin or browser-source overlay fed by a streaming ASR API (e.g., Deepgram, AssemblyAI, or Whisper with a streaming wrapper) and a translation API such as DeepL. The hard part is end-to-end latency, chunking and stability of partial transcripts, and handling timing and dropouts during live streams. This needs real-time audio engineering experience and load testing, not just prompting.
