Overview
Add furigana (reading annotations) to Japanese text on any website using EZFurigana backend
Tsukeru is a lightweight furigana converter that helps you read Japanese text by adding hiragana readings to kanji directly on the page. It works as a Japanese reading aid for learners, allowing you to convert kanji to hiragana using ruby annotations without leaving the site you are reading. Furigana is applied only on the active tab and only when you explicitly trigger it. Tsukeru is powered by the EZFurigana backend and is designed to be fast, simple, and privacy-first. Key features: - Add furigana to Japanese text with one click - Convert kanji to hiragana directly on the page - Works on the active tab only - Optional support for dynamic content (infinite scroll / SPAs) - Dictionary popups and vocabulary saving - Keyboard shortcut (Ctrl+Shift+F) to toggle furigana - Compatible with many popular sites such as YouTube, X (Twitter), Reddit, and more Privacy: - Tsukeru does not collect, track, or store user data - Text is sent to the backend only when you click “Apply Furigana” - Text exists on the server only for the duration of processing and is not logged or retained - No analytics, trackers, or third-party scripts Permissions are kept to the minimum required for functionality and are used only after explicit user action.
