Hey Product Hunt 👋 I'm Zero, the maker. AI Shadowing is the tool I built for myself — a way to use YouTube for language learning without the friction that nearly made me quit twice. Quick context: I went from German A0 to A2 in about 3-4 months by shadowing native YouTube videos, 30-45 min a day. The technique works — I got to where I could follow casual dinner chitchat with my friend's parents (not the jokes or fast bits, but enough to nod along and ask follow-ups). But the *process* was brutal: 1. To replay one sentence: drag YouTube scrubber → overshoot → drag again → wait for buffer. Rhythm dies every time. 2. Unknown word? Switch to dictionary app, come back, scrub to where you were. Five seconds of friction every minute, for an hour straight. 3. YouTube's own captions are built for reading along, not practicing — auto-generated on most videos, no punctuation, split mid-sentence every ~3 seconds, no way to loop, no inline lookup. AI Shadowing fixes all three: 🎯 Paste any YouTube URL → sentence-by-sentence transcript with proper punctuation (AI cleans up the raw captions) 🔁 Click any sentence to loop it instantly — no scrubbing 📖 Click any word for an instant AI grammar explanation that actually answers the follow-up questions I'd save for my teacher ⏱️ Configurable pause between sentences for shadowing practice 📁 Also: upload your own audio (MP3 / MP4 / ZIP), same shadowing UI, syncs across browser + phone Some honest scope so you don't have to ask: - Not for absolute beginners (A0). Start with a textbook + basic vocab first; shadowing is the next layer. - Won't replace conversation practice. This is the missing piece for the lonely middle of self-study, not a full program. - I personally use the **Android version** way more — phone in pocket means I practice on the bus, walking, waiting in line. It's not on Play Store yet (web is what's live). If today's launch shows interest, I'll push the Android build through. Tech (since this crowd cares): Flutter (Web + Android), Gemini for caption cleanup + the click-to-explain feature, Google Cloud TTS for pronunciation. Built solo over ~3 months, evenings + weekends. Free, no signup. 11 languages: English, German, Spanish, French, Italian, Portuguese, Russian, Japanese, Korean, Simplified + Traditional Chinese. Monetization: nothing yet. Server-side AI + TTS isn't free, so likely freemium later — but I want to see what people actually use first. Would love brutal feedback, specifically: - What language are you learning, and is the workflow missing something for that language? - Which feature is the "I'd come back for this" hook, and which feels like noise? - What would make you switch from whatever you currently use (or what stops you from shadowing at all)? Thanks for taking a look 🙏
