Toku turns native Japanese and Chinese — articles, novels, podcasts, and YouTube videos — into something you can actually read. Tap any word for its reading, meaning, and dictionary, without leaving the page. On audio and video you get a synced, word-tappable transcript: tap to learn, slow it down, replay a line, or pause after each sentence to shadow it back. It runs its own JP/CN engine on-device with offline dictionaries — fast, private, no accounts, no streaks. Just reading.

Hi Product Hunt 👋 I'm Darren, the maker of Toku. I built it because reading native Japanese and Chinese — a news article, a novel, a podcast — meant constantly stopping to look words up, and that kills the flow. So Toku does the looking-up for you: tap any word and its reading, meaning, and dictionary entry appear right there. It works on text you paste, web pages, and the part I'm most excited about — real podcasts and YouTube videos. You get a synced, word-tappable transcript: tap a word to learn it, slow the audio down, replay a line, or pause after each sentence to repeat it out loud (shadowing). Under the hood it runs its own Japanese & Chinese engine on-device with offline dictionaries — fast, private, works on a plane. No accounts, no streaks nagging you. Just reading. I'd genuinely love your feedback — what's confusing, what's missing, what you'd want next. Thank you for taking a look 🙏

the "tap any word on a youtube video or podcast" part is the bit that matters. most immersion apps make you leave the content to look something up, which kills the flow and the motivation right when you had it. keeping the lookup in place on real native material (novels, podcasts, video) is how people actually stick with a language instead of grinding flashcards. congrats on the launch.
