Burned-in subtitles on video platforms cannot be extracted or transliterated, blocking pronunciation practice. A Chrome extension that OCRs on-screen subtitles in real time, translates and outputs pinyin, plus saves snippets for SRS, solves the workflow for daily learners.
Burned-in subtitles on video platforms cannot be extracted or transliterated, blocking pronunciation practice. A Chrome extension that OCRs on-screen subtitles in real time, translates and outputs pinyin, plus saves snippets for SRS, solves the workflow for daily learners. User evidence shows daily usage and a paid workaround signal, indicating immediate demand for a smoother flow. Recent advances in lightweight OCR and transliteration models that run in-browser or via small backend services, plus wide adoption of Chrome extensions and rising consumption of short-video platforms, make low-latency, in-context subtitle capture and pinyin generation technically and commercially feasible now. Combine real-time browser-based OCR tuned for subtitle fonts and motion with on-the-fly translation and accurate pinyin transliteration, plus a lightweight SRS export and per-user vocabulary cache. The founder evidence shows a daily habit and paid-workaround willingness, so integrating capture-to-practice in the extension creates workflow lock-in as users accumulate phrase lists and study history.
