No deck maintenance
Review comes from your live mistakes and due skills, not from cards you had to build, tag, and prune yourself.
Japanese · Spanish · English
Shaded learns where language breaks down for you.
Practice real sentences. Get feedback tied to the words, patterns, and skills you actually missed. Then keep moving through lessons built around what you are ready to use next.
Learning
Not a deck · Not a fixed course · Not an open-ended chatbot
Why it feels different
Not flashcards. Not a fixed course. Not just a chatbot.
Shaded is a guided learning system that watches how you answer, finds the weak spots underneath, and turns them into the next useful practice step.
No one-size-fits-all path
Two learners can practice the same language and see different prompts because their weak spots are different.
No ungrounded chat drift
Flexible AI practice is paired with anchors, reviewed material, and source-backed examples wherever Shaded can use them.
What Shaded actually learns
It breaks every sentence into the pieces you actually learn.
Each piece is pulled from what you say, anchored to a real source, and tracked on its own — so practice targets the exact thing that tripped you up.

In Japanese, grammar rides on particles — は and を become pieces of their own.

One unit, three ways Shaded knows it —食べる· to eat
Grounded, not guessed
Checked against a real dictionary or source — not an AI's hunch.
anchors · provenanceOne meaning, many forms
食べる, 食べます, 食べた are one unit to learn — not three cards.

How it works
It understands the shape of your mistakes.
A missed answer is not just right or wrong. Shaded looks for the word, pattern, skill, and direction that made it hard, then uses that signal to choose what happens next.
01
It gets where you are stuck.
Practice real sentences across reading, listening, writing, and speaking. When something breaks, Shaded keeps track of the part that broke instead of treating the whole exercise as a mystery.
02
Your next lesson comes from real practice.
Shaded turns recent misses, due review, ability level, and session goals into focused practice. You do not have to tune a queue to keep seeing the right challenge.
03
It follows you across modes.
Flow, Passage, goals, concepts, and Voyage all draw from the same learner model. Switching modes should feel like changing the exercise, not starting over.
Grounded AI practice
AI can make practice flexible. Anchors keep it honest.
Shaded grounds explanations in dictionaries, source examples, and reviewed learning material whenever possible, so generated practice does not drift away from the language you are trying to learn.
Momentum you can see
Progress is not hidden in a review queue.
Your home map, goals, concepts, and Voyage all show what changed and what to do next. Daily progress becomes visible without making you manage the machinery underneath.
Know what is due
Reviews return when a word, pattern, or skill needs attention.
See the next step
Flow and Passage give you focused ways to practice from the same progress model.
Keep the reward visible
Goals and Voyage turn daily study into a route you can watch advance.
Across language pairs
It understands direction, not just language names.
Japanese speakers learning English
Shaded can guide a Japanese-speaking learner through English workplace, commute, and daily-life practice with Japanese explanations where they help.
English speakers learning Japanese
Kana, particles, readings, and sentence patterns can be introduced with the scaffolding a beginner needs, then eased back as they stick.
English speakers learning Spanish
Practice can focus on verbs, agreement, listening, and real sentence use instead of isolated vocabulary lists.
Different modes, same learner
Flow, Passage, goals, and concept review share progress, so the app keeps the same sense of you as you move around.
Now on the web
Start on your phone. Keep the same learner model in the browser.
The web app at shaded.app syncs with iOS and Android, so the weaknesses Shaded found on your commute can become the focused session you continue at your desk.
Open Shaded on web
Built for the messy middle
For the stretch between knowing a rule and using it naturally.
The value is not that Shaded generates more practice. It is that Shaded keeps learning from what happens when you try to use the language.
