About

Tsukeru is a lightning-fast, privacy-first Japanese reading aide that injects furigana (hiragana readings) directly above kanji on any webpage—without breaking the layout!

Whether you are studying for the JLPT or just trying to navigate native Japanese websites, Tsukeru is designed to make reading effortless. Simply hit Ctrl+Shift+Z and watch the kanji instantly transform into readable text.

Unlike heavy offline dictionary extensions, Tsukeru is powered by the incredibly fast EZFurigana API, returning perfectly matched ruby annotations in milliseconds.

🌟 KEY FEATURES:

- One-Click Furigana: Convert complex kanji to hiragana instantly on the active tab.
- Deep Website Support: Fully compatible with dynamic, infinite-scroll sites like YouTube (Subtitles & Comments), X/Twitter, and Reddit.
- Inline Dictionary Tooltips: Click any word to instantly reveal English definitions, JLPT levels, Part-of-Speech, Example Sentences, and Kanji breakdowns.
- Vocabulary Builder & Anki Export: Save unknown words directly from the tooltips. Export your entire list as a .zip containing CSVs and native MP3 TTS audio, perfectly formatted for 1-click Anki importing!
- Customizable Aesthetics: Control the size, weight, and color of your furigana.
- Smart JLPT Filtering: Hide simple kanji readings (like N5 or N4) to drastically reduce visual screen clutter and challenge yourself.

🛡️ Privacy and Security:

- Active Tab Only: Tsukeru does absolutely nothing until you manually click the button or use the keyboard shortcut. It never runs passively in the background.
- Zero Telemetry: We do not collect, track, or store any user data.
- Ephemeral Processing: Text is sent to the backend strictly to apply readings, processed entirely in memory, and immediately discarded. Nothing is ever logged or retained.
- No Third-Party Scripts
