Learn the Right Words,
in the Right Order
Most courses teach vocabulary by theme. Insperium teaches by frequency — so every word you learn gives you the maximum return on your time.
Why Most Language Courses Get It Wrong
Traditional courses teach by theme: “At the Airport”, “Food & Drink”, “The Classroom”. The problem? You learn “cucumber” before “want”. You memorize “boarding pass” but can't say “because”. Theme-based ordering ignores how language actually works.
Theme-Based (Traditional)
- Lesson 1: Airport vocabulary (20 words you rarely use)
- Lesson 2: Food vocabulary (know “cucumber”, can't say “because”)
- Lesson 3: Classroom words (still can't form basic sentences)
- After 200 words: ~40% daily language coverage
Frequency-Based (Insperium)
- Block 1: The 75 most used words in all Chinese media
- Block 2: The next 75 most common words
- Block 3: And so on — always maximum impact
- After 200 words: ~80% daily language coverage
Built on SUBTLEX-CH
Our curriculum is built on SUBTLEX-CH — a frequency database compiled from 33 million words of real Chinese film and TV subtitles. This reflects how Chinese is actually spoken, not how textbooks think it should be.
Three Pillars of Insperium
Frequency-First Vocabulary
4,050 words in 54 blocks of 75, ordered by how often they appear in real Chinese. Every word you learn maximizes your comprehension.
Graded Comprehensible Input
9,000+ sentences, 640 stories, 594 dialogs — all constrained to vocabulary you've already learned. No surprise words, no guessing.
Leitner Spaced Repetition
5-box SRS system with audio. Words move up when correct, drop back when wrong. Science-proven to maximize long-term retention.
The AI Study Coach
Not a chatbot. A real planning engine that tracks your SRS box distribution, retention rate, quiz scores, listening time, and reading progress — then generates a personalized daily session.
Adaptive Pacing
If reviews pile up, it slows new words. If you're crushing it, it speeds up.
Daily Session Plans
Review → New Words → Sentences → Listening → Quiz. Built fresh each day.
Goal-Based
Set your pace: 30 min/day, 60 min/day, or crash mode for exam prep.
Weakness Detection
Identifies problem areas and adjusts focus. Listening weak? More listening drills.
