What is Toku Reader?

Toku Reader is an iPhone app that turns native Japanese and Chinese content—articles, novels, podcasts, and YouTube videos—into something you can actually read. Tap any word to instantly see its reading, meaning, and dictionary entry, all 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 Japanese and Chinese engine on-device with offline dictionaries—fast, private, no accounts, no streaks. Just reading.

Who it's for

• Language learners who want to read real native content without constantly switching to a dictionary or translation app.
• Self-study enthusiasts who prefer offline, private tools over cloud-dependent apps with streaks and gamification.
• Advanced readers who need fast, inline lookups for kanji, furigana, pinyin, conjugation breakdowns, and pitch accent across web pages, PDFs, EPUBs, video subtitles, and podcasts.

Key features

Tap-to-read across all content types

Paste or import texts, PDFs, and multi-chapter EPUBs. Browse real websites with readings added directly to the page—complete with tabs, history, and a distraction-free reading view. Watch videos with interactive subtitles you can search, tap, and read line by line. Listen to podcasts with a tappable, word-by-word transcript—follow shows, download episodes, and practice shadowing.

On-device dictionary and study tools

Tap any word for its meaning, readings, animated stroke order, and radical breakdown. A full dictionary tab includes handwriting input, English reverse search, and side-by-side Simplified and Traditional Chinese. Save words to a built-in spaced-repetition review deck, or import your existing Anki deck and keep your scheduling history intact.

WaniKani integration

Connect your WaniKani account to study radicals, kanji, and vocabulary directly in the app. Your SRS progress stays in sync, and known kanji light up inline as you read—so you always know what you've already mastered.

Offline-first design

The core experience works offline: tokenization, dictionaries, OCR, and reviews all run on-device. Your reading stays on your device, with no accounts, no streaks, and no cloud dependency.

What stands out

"Just reading."

That's the entire philosophy of Toku Reader. While most language apps push gamification, streaks, and cloud sync, Toku strips everything away except the act of reading itself. Every feature—from inline tap-to-define to offline dictionaries to WaniKani sync—exists to remove friction between you and the text. The result is an app that feels less like a study tool and more like a superpowered reading environment.

Worth checking out if…

You're learning Japanese or Chinese and want to read real native content—web articles, novels, manga, YouTube videos, or podcasts—without constant dictionary interruptions. You value privacy, offline access, and speed over gamified streaks. You already use Anki or WaniKani and want seamless integration. And you're on iPhone, because Toku Reader is currently iOS-only.
