Kanji Lens: Japanese Manga Translator & Learning Tool

Kanji Lens is a browser extension that helps you memorize kanji directly from manga panels.

Instead of studying from dry word lists, you learn kanji in context: from the manga panels you’re already reading. The extension scans each panel, extracts the kanji from the image, and shows you readings, meanings, and furigana directly on top of the manga page. Any kanji you tap can be saved and reviewed later with a built‑in spaced‑repetition system. Each kanji is color‑coded by progress (Difficult, Learning, or Mastered), so you can instantly see which Kanji still need work and which ones you’ve already mastered.
