Read the Japanese web as it is

Japanese text does not get easier because you pasted it into a translator: what you need is to keep reading the page, with help in the right place. The extension works on the page's text nodes and adds reversible ruby tags, leaving the layout untouched.

Frequently asked questions

Does the extension work on Firefox?

Not yet. The current package uses a service worker, which Firefox refuses; a port is planned.

Are the pages I visit sent anywhere?

No. The dictionary is downloaded once and stored locally, and analysis happens in the browser.
