Hi Product Hunt! 👋 I'm a foreign-trade professional who talks with overseas clients in English every day —but after years of business English, real native YouTube videos still left me lost. Textbooks taught me "fine," not fluency. So I built TubeFluent. It turns any YouTube video or podcast into a lesson: • Bilingual subtitles —read along in your native language • Tap any word →instant dictionary + pronunciation • Words you look up become your spaced-repetition review automatically • An AI speaking coach to practice actually speaking • A learning path that keeps you at "just hard enough" Today it has 20,000+ leveled videos, 70,000+ podcast episodes, and 100+ books. I built every part of it myself — recommendation engine, billing, everything. It's free to start, and I'm here all day to answer questions. Ask me anything about the tech stack, language learning, or being a solo founder!

I've been building TubeFluent, an app that turns YouTube videos into English lessons inline word lookup, AI speaking practice, pronunciation scoring down to the phoneme level, and a 5-dimension growth tracker (listening/speaking/reading/writing/vocabulary) instead of a simple streak.

Before I launch, I'd love to hear from people who've tried other language apps (Duolingo, Trancy, etc.) what's the one thing that made you quit, or the one thing you wish existed?
