About KanjiLens Expand
KanjiLens offers an immersive way for Japanese learners to expand their vocabulary and kanji knowledge while reading. It integrates as a browser extension, allowing users to look up unfamiliar kanji and translate images directly within their favorite manga and novels.
This approach removes the common friction points of switching between apps or manually looking up words, keeping learners engaged with their content. The product includes a spaced repetition system (SRS) to reinforce new vocabulary, turning casual reading into an effective study session.
Its freemium model makes it accessible, with a paid tier for more intensive use.
