Kioku is a free Chrome add-on developed by Kioku that aims to help users learn Japanese while browsing the web and watching Netflix. This powerful tool keeps track of your known words and provides assistance when reading regular websites and watching Netflix.

One of the main features of Kioku is its ability to highlight words that you are still learning or don't know yet.
