Read full descriptionHide full description
Read Japanese at the level that works for you. Paste Japanese or English text, or choose a short reading from the built-in library. Levelify creates Hard, Medium, and Easy Japanese rewrites, so you can compare them and choose the version that feels most comfortable. When you enter Japanese text, you can also show readings above its kanji. Adjust the amount of furigana to get more support when you need it or keep familiar kanji unmarked. 【What you can do】 Switch between the Japanese text you entered and three rewritten versions. Use Levelify with a sentence, message, article, or note, or open a built-in reading for a quick practice session. 【Keep useful rewrites】 Find recent rewrites in History and add favorites to Saved. You can also copy or share the Japanese text from the result screen. 【Who it's for】 Levelify is for learners who want more support when reading Japanese beyond the textbook, including news, posts, messages, and everyday writing. 【Notes】 Output is AI-generated and is not human-reviewed. It may be inaccurate, incomplete, unnatural, or miss nuance. Check the Original (the text you entered) for important legal, medical, financial, academic, or safety-related information. 【Terms of Use】 https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
