Select Japanese text to see furigana in a tooltip — zero page modification Most furigana extensions work by injecting HTML directly into the page — replacing text, adding ruby tags, and breaking layouts. Furigana Tooltip does none of that. Select any Japanese text on any website and a clean tooltip appears above your selection showing kanji with their hiragana readings. The page is never touched. When you're done reading, click anywhere or press Escape and it disappears. Works everywhere — static pages, React and Vue apps, news sites, Twitter, Google Docs, anywhere text exists Zero page modification — no injected HTML, no broken layouts, no font changes, no copy-paste interference Offline — readings are generated locally using an embedded Japanese dictionary. Nothing you read is ever sent to a server On demand — furigana only appears when you select text, not automatically on every kanji on the page Built for Japanese learners who want to check a reading quickly without interrupting what they're reading.
