Could you build this?
Partial The phrasebook, history, and UI are easy to vibe-code, but fully offline speech recognition and translation across 11 languages needs on-device ML models and tuning that vibe coding alone won't deliver.
What it would actually take: A real version would bundle on-device speech-to-text (e.g., Whisper variants) and offline machine translation models (e.g., quantized NLLB or Marian-style models) into a mobile app via Core ML, TFLite, or ONNX Runtime. The hard parts are model size, latency, and translation quality on phones, which need ML engineering and mobile performance expertise.
