About this app

Ready to take your Japanese reading and listening comprehension to the next level? Welcome to Satori Reader.

HUNDREDS OF ARTICLES
Read from a growing library of articles written by native speakers for intermediate students, organized into interesting series such as news, stories, dialogs, 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)
Create review cards instantly as you read. Later, review them using the built-in spaced repetition system. Each card you create takes along a snapshot of the sentence in which you encountered the word. You can even listen to the audio for those sentences during reviews to further cement the word into memory.

HUMAN FEEDBACK
Still confused about something? Just ask in the comment section below each article. Knowledgeable staff are ready to help.

Satori Reader is built by a team that cares. Our goal is to bring satori (enlightenment) into your Japanese reading life. Set up a free account today, and let's get started.

Reading is undeniably the hardest part of Japanese, and this app is the best way to get good at it - and/or at listening, too. It's a lovingly crafted and regularly updated collection of stories - all professionally (and immersively) voiced over, and hand-annotated with very useful commentary on the finer points of language and grammar (adapted to the difficulty of the story, so always relevant). It also has a built-in flashcards system to help you memorize things, but I haven't used that much.

I love this app, and have been using it for years. The stories are fun and engaging, and the ability to click on words to see their translations, or play the audio of either specific sentences or the entire chapter, are super useful. It also lets you easily create flashcards with spaced repetition reviewing, and some stories have both simple and advanced versions. It gives context and explanation for grammar and word usage in translations. Thank you to all who worked on it!

This has supercharged my language acquisition. This story-based method, with audio, sound effects, show/hide translation, furigana markup and rich contextual info is exactly what I needed. Update: startup time seems a little faster, good. Suggestion: it would be good if it were a bit easier to find my way to where I am in each story. As it is, I'm working with bookmarks, but I have to remember to delete and add them.
