Mazelingo is a web reader for Japanese speakers who want to read more English. Paste any Japanese text, such as a news article, blog post or your own notes, and Mazelingo mixes English sentences into it. You choose the amount of English (20%, 40%, 60% or 80%) and the difficulty (easy or standard) separately. Tap an English sentence to see the original Japanese. There is no API key or AI model to configure, and guests can try three readings a day.
