What does this character mean?
Most Chinese apps teach you to tap, not to think
- Duolingo teaches you to match pictures, not read a menu
- Anki expects you to build your own curriculum from scratch
- Generic SRS apps drill vocabulary in isolation, disconnected from real Chinese
What makes this work
Adaptive drills
44 drill types across reading, listening, speaking, and writing. The system tracks what you get wrong and adjusts. No wasted repetition.
Graded reading
Read real Chinese passages at your level. Tap any word for instant pinyin and translation. Every lookup feeds back into your drill queue.
Listening practice
Listen to passages at adjustable speed. Reveal the transcript when you're ready. Build comprehension, not just vocabulary.
HSK aligned
Content structured around HSK 1-9. Track your projected exam readiness. Know exactly where you stand and what to work on next.
The cleanup loop
Go live in Chinese
Read a graded passage. Watch a show. Listen to a podcast. Encounter real language.
Look up what you don't know
Every word you tap to check gets logged. The system sees exactly what you struggled with.
Drill your real gaps
Your next session prioritizes the words you actually needed. Not a textbook list — your list.
Memory fades. Review renews.
Without review, a new word fades within days. Spaced repetition brings it back at the exact moment you'd forget.
Each pulse is a review session. The curve gets shallower every time.
Fast and consistent
Every drill, every score, every recommendation is deterministic. The same right answer every time. Responses are instant.

Built on research, not guesswork
Aelu's scheduling algorithm is based on FSRS (Free Spaced Repetition Scheduler) with confidence-weighted scheduling — the same family of algorithms used in peer-reviewed spaced repetition research. Every drill, every interval, every difficulty rating is computed deterministically. No variable quality.
