Ready to take your Japanese reading and listening comprehension to the next level? Welcome to Satori Reader. COMPELLING STORIES Read from a growing library of engrossing stories written by native speakers for intermediate students, across genres such as fantasy, slice-of-life, thrillers, documentaries, news, and more. AUDIO Tap any sentence to hear it read aloud by native voice actors (no robots!). ADAPTIVE KANJI USAGE Crack the chicken-and-egg problem of reading kanji with our unique presentation engine, which adjusts the Japanese text to accommodate your actual knowledge. This allows you to challenge yourself for the kanji you should know without being overwhelmed by what you don't. SMART DEFINITIONS Tap any word for a definition. This is more than just an automated lookup. Satori Reader shows the actual sense of each word as it's being used in the sentence. For example, the particle の has many uses: it can indicate possession; it can turn the preceding verb or phrase into a noun; it can stand in for another word; and more. We show you exactly what is happening in every instance of every word. FRIENDLY ANNOTATIONS Gray underlines indicate longer annotations that break down tricky expressions, provide cultural background, or help you to read between the lines. Our editors work hard to anticipate what might be confusing and proactively help you to make sense of things. Good-bye, confusion. Hello, clarity! SPACED REPETITION SYSTEM (SRS) The built-in spaced repetition review system helps you to build your vocabulary. Create review cards instantly as you read. Each card you create takes along a snapshot of the sentence in which you encountered the word, further helping to cement it in your memory. You can even play back the audio of that sentence while reviewing the word! HUMAN FEEDBACK Still confused about something? Just ask in the discussion section below each episode. Our team of friendly human beings is ready to help. Satori Reader is built by a team that cares. Our goal is to bring satori (enlightenment) into your Japanese reading life.

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 provides the translation, vocabulary, and 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? The 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 just 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. Wakatta?
