Wakatta! Japanese Analyzer

Understand Japanese sentences — not just the words, but the grammar.
Paste a sentence and get a context-aware translation, word breakdown, grammar notes, and JLPT level estimate in seconds.

Wakatta! is an AI-powered Japanese sentence analyzer built for learners who want to understand how Japanese works.
Paste Japanese text from manga, anime subtitles, news articles, song lyrics, or everyday conversation. Wakatta! instantly analyzes the sentence and will provide the translation + vocabulary + grammar breakdown in one clean view. You don’t have to bounce between a translator, dictionary, and grammar guide anymore.

What you get for each analysis:
▶ Full English translation: Natural, context-aware translations. Not robotic word-for-word output, but fluent English that captures the real meaning.
▶ Word-by-word breakdown: Every word displayed with furigana readings, English meaning, and part of speech. See exactly how each word contributes to the sentence.
▶ Grammar pattern explanations: Wakatta! identifies grammar structures and explains them clearly. Confused by particles like wa, ga, or wo? Wondering when to use te-form? Our sentence analyzer breaks it down.
▶ JLPT level tags: Every grammar point is tagged with its JLPT level from N5 (beginner) to N1 (advanced). Know exactly where each pattern falls in your Japanese learning journey.

Accepts any Japanese input format
Type or paste Japanese in any form: hiragana, katakana, kanji, or even romaji using English letters. Don't have a Japanese keyboard? No problem. Enter "watashi wa nihongo wo benkyou shiteimasu" and Wakatta! will analyze it exactly like the full Japanese sentence with kanji.

Most Japanese learning apps require proper Japanese input. Wakatta! is different: romaji works perfectly, making it accessible for complete beginners who are just starting to learn Japanese.

Who Wakatta! is for
√ JLPT learners (N5 to N1) using real sentences as study material
√ Manga and anime fans who want to understand dialogue without guessing
√ Self-study learners who want the “why”, not just the meaning
√ Students supplementing textbooks with real-world Japanese

Why it’s different
Most translation apps stop at the meaning. Most dictionary apps stop at definitions. Wakatta! goes further and shows the sentence structure: words, grammar, and level — so you actually learn from what you read.
