Burned-in subtitles on YouTube, TikTok and Instagram are not copyable and often lack pinyin. A Chrome extension that captures subtitle overlays in real time, OCRs/translates them and generates pinyin and exportable flashcards.
Burned-in subtitles on YouTube, TikTok and Instagram are not copyable and often lack pinyin. A Chrome extension that captures subtitle overlays in real time, OCRs/translates them and generates pinyin and exportable flashcards. Short-form and social video platforms increasingly burn text into video to aid engagement, creating more study material that is not machine-readable. Browser extension APIs and on-device OCR have matured enough for reliable real-time capture of rendered subtitles. The source reports daily usage and a paid-workaround willingness, and the user timeframe (travel to China in 2 months) demonstrates urgency and habitual study patterns that enable fast user adoption. This extension targets the learner workflow end-to-end: real-time capture of subtitle overlays from multiple platforms, robust OCR tuned for common subtitle fonts and styles, immediate pinyin romanization and translation, plus export to SRS/Anki or phrase lists. Evidence from the source: user needed to capture subtitles embedded in video frames and convert them to pinyin to practice daily, showing a recurring learning habit and a concrete unmet need that browser-level capture plus pinyin conversion directly solves.

Capture burned-in video subtitles and convert to pinyin for learners targets a $1.2B = 2M users x $5/mo x 12. Rationale: target global active language learners who use video as a study channel; 2M paying users at a $5/mo consumer ARPU is a conservative TAM for a niche EdTech tool. total addressable market with medium saturation and a year-over-year growth rate of 10-15% growth for language learning app usage driven by mobile and video consumption.
Key trends driving demand: Burned-in subtitles in short-form video -- more native-language learning content is delivered with non-extractable captions, creating a new need for capture tools.; Rise of immersion learning via native content -- learners prefer native materials and microlearning from clips, increasing daily usage frequency.; Improved client-side OCR and romanization libraries -- makes accurate real-time extraction and pinyin conversion feasible in extensions..
Key competitors include Language Reactor (formerly Language Learning with Netflix), Substital, Project Naptha, Mate Translate / general translator extensions, Workarounds: manual transcription, downloading subtitles, Anki import.

People spend disproportionate time creating, formatting and verifying citations. AI can extract sources, generate correctly styled citations, and produce verifiable reference trails inside writers' workflows.
Libraries are pressured to label reference librarians as "AI experts" despite their domain skills. Build an AI‑augmented reference platform that encodes librarian interview expertise, integrates local collections, and provides training + governance.
Problem: students and hobbyists waste time relearning new PCB tools as they progress. Solution: an education-first, KiCad-based platform + guided curriculum, AI tutors, and factory integration that teaches one tool for life—from class projects to production.
Many SQL resources are dry or toy-like. Build an interactive, narrative SQL practice game set in a fictional Singapore bank with realistic datasets, progressive challenges, and instant feedback to teach practical querying skills.
Large institutions struggle to issue thousands of digital certificates reliably and verifiably. This solution automates generation, personalization, delivery, and verification at cohort scale with analytics and compliance hooks.
Law students and junior associates struggle to run realistic mock trials because recruiting actors, judges and opposing counsel is costly and slow. An AI platform simulates multiple courtroom roles, gives feedback, and scales practice on demand.
