PuzLing uses its innovative “partial translation” technique to teach you a language faster. Every English sentence you encounter will have some of it’s words and phrases swapped to Japanese. Words are chosen based on the skill of the learner - the better you get, the more Japanese you’ll encounter. It works in reverse too; text on Japanese sites will be swapped to English, so you can learn from native language content. Try it out by clicking on words in this paragraph, or see more by scrolling down the page.
