KaiwaLens

JAPANESE ON SCREEN

Read the Japanese on your screen.

Point KaiwaLens at any part of your screen and it reads the Japanese there, splits it into words, and shows you the reading and meaning of each one: a game, a manga page, a PDF, a video, a website that will not let you select text. It runs on your computer. No account, no subscription, nothing sent anywhere.
