Could you build this?

Partial The app shell, word lookup, and saved vocabulary are vibe-codeable, but licensed native-speaker video content and accurate word-level timed transcripts are hard to get without rights and a curation pipeline.

What it would actually take: The stack is a video feed, with ASR (such as Whisper) plus forced alignment for word-level timestamps, Chinese segmentation (jieba), and dictionary data (CC-CEDICT) for pinyin and meanings. The hard parts are securing rights to a large library of native-speaker clips and checking transcript and alignment quality. That requires content licensing deals and some human review, or a creator partnership.
