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.

Shaded learns where language breaks down for you. Practice real sentences in Japanese, Spanish, and English. Get feedback tied to the exact words, patterns, and skills you missed. Then keep moving through lessons built around what you're ready to use next. NOT FLASHCARDS. NOT A FIXED COURSE. NOT A CHATBOT. Shaded is a guided learning system that watches how you answer, finds the weak spots underneath, and turns them into your next useful practice step. • No deck maintenance — review comes from your live mistakes and due skills, not from cards you build, tag, and prune yourself. • No one-size-fits-all path — two learners practicing the same language see different prompts, because their weak spots are different. • No ungrounded chat drift — AI practice is paired with dictionary anchors, reviewed material, and source-backed examples. IT LEARNS THE PIECES, NOT JUST THE SENTENCE Every sentence you practice is broken into its real units — words, particles, patterns — and each is tracked on its own: • Grounded, not guessed: checked against real dictionaries and sources, not an AI's hunch. • One meaning, many forms: 食べる, 食べます, and 食べた are one thing to learn, not three cards. • Known by skill: reading a word isn't saying it. Reading, writing, listening, and speaking are tracked separately. MODES THAT SHARE ONE LEARNER MODEL • Flow — focused practice built from recent misses, due review, and your level. • Passage — read and listen to longer material chosen for what you're ready for. • Goals & concepts — see what's due, what changed, and what to do next. • Voyage — your progress as a route you can watch advance. Daily study moves the ship. BUILT FOR REAL LANGUAGE PAIRS English speakers learning Japanese (kana, particles, readings, and sentence patterns, with scaffolding that eases off as things stick) or Spanish (verbs, agreement, and listening in real sentences) — and Japanese or Spanish speakers learning English, with explanations in your language where they help. SYNCED WITH THE WEB Start on your phone; continue at shaded.app in any browser. The weaknesses Shaded finds on your commute become the focused session you finish at your desk. Built for the messy middle — the stretch between knowing a rule and using it naturally. Shaded keeps learning from what happens when you try to use the language.

Verdict

The call

The clearest difference is ads: Satori Reader at none against Shaded Learning's shown. Satori Reader also leads on ratings volume (215 vs 3). Shaded Learning's advantage is update cadence (weekly vs every 3 months) and rating (5.0 vs 4.8). On price, in-app purchases, monetization model and device support there is nothing between them.
