Hi Hunters! 👋 I'm the solo developer behind LinguaMaster. Like many of you, I spend hours watching YouTube in my target language. But I realized something frustrating: I was consuming content, not acquiring language. I’d watch a 20-minute video, enjoy it, but fail to retain any new vocabulary or understand the cultural nuance behind the jokes. Existing tools were either too simple (just dual subtitles) or too rigid (flashcard apps). I needed a "Flow State" environment where I could watch, analyze, and save words without context switching. So, I "vibe coded" LinguaMaster into existence. 🚀 What makes it different? Local-First & Private: Your learning data stays on your machine. No tracking. Context-Aware AI: It doesn't just translate; it explains why a sentence is structured that way based on the video's context. Studio Layout: A split-screen design engineered to keep you in the zone. Zero Config: It works out of the box with 500 free monthly AI credits (or bring your own API key for unlimited power). I'm currently in v0.6.1 Public Preview and would love your brutal feedback. Does the "Studio Layout" work for you? What features are missing? Let me know in the comments below! 👇 Happy Learning!
