Everything You Need for Complete Vocabulary Mastery
From scientifically curated curricula to AI-powered sentence practice, Lexiage provides a complete vocabulary development system — for individuals, families, and schools.
The 5 Learning Modes
Each mode is harder than the last — a deliberate progression from guided first contact to speed-tested mastery. Together, they form a pipeline that guarantees permanent, automatic recall.
Learn
Guided first encounter — zero failure, 100% success
Why this mode exists
The brain needs a scaffolded, stress-free first encounter with a new word. Learn Mode provides guided, letter-by-letter typing where the system only accepts the correct letter at each position — forming the first accurate memory trace.
How it works
The word appears on screen with guided typing. Then the word flashes at progressively faster speeds, building from recognition to recall. The system adapts to the student's pace.
There is no failing in Learn Mode. Every word ends at 100%.
The Mastery Pipeline
Learn → Practice → Imprint → Play → Correction (if needed) → Play again. The difficulty increases with each mode. If any words are missed in Play, they are sent to Correction before the student can attempt Play again. 100% accuracy in Play = mastery.
18 Levels of Curated Wordlists
Built from five major linguistic datasets — including the 60,000-word COCA frequency corpus, Oxford CEFR classifications, and academic vocabulary databases. Every word is selected based on frequency, academic importance, and developmental stage.
Core wordlists form the backbone — required for progression. Elective wordlists unlock after mastering the core, allowing deep dives into domains like medicine, history, science, and literature. Rigour without rigidity.
The Lexicon Engine
How Lexiage selects, organises, and sequences every word in the curriculum.
Frequency-Based Selection
Words are selected based on how often they appear in real-world English, using the COCA corpus of 60,000 words ranked by frequency of use.
CEFR Classification
Every word is mapped to the Common European Framework of Reference for Languages, ensuring age-appropriate and difficulty-appropriate placement.
Academic Vocabulary Integration
Academic word lists (AWL) are integrated into the upper levels, preparing students for university-level reading and writing.
Developmental Staging
Words are assigned to levels based on the age at which they become essential, aligned with cognitive and educational milestones.
Multi-Language Parity
The same rigorous selection process is applied across all system languages, ensuring consistent quality across English, Portuguese, French, Spanish, German, and Italian.

Word Workshop
After the modes prove you can recognise and spell a word, the Word Workshop proves you understand what it MEANS and can USE it. AI-powered sentence practice converts recognition into genuine ownership.
During any learning mode, flag words you want to explore deeper.
In the Word Workshop, write original sentences using each flagged word.
An AI evaluator provides instant feedback — checking grammar, meaning, context, and spelling.
Three correct sentences required per word — proving consistent understanding, not a lucky guess.
Creative, informal, and figurative uses are accepted. It tests understanding, not conformity.
The learning modes prove you can recognise and spell the word. The Word Workshop proves you can USE it. This is the difference between passive memory and a living, active tool in your mind.
Study Decks
The deepest form of learning is constructing it. Study Decks put the learner in the role of creator — building flashcards, writing definitions, and proving understanding through active recall.
Create decks with terms, definitions, and optional images.
Active recall flow: write your answer → compare → rate yourself (1–3) → revise.
3 correct recalls required per card to prove understanding.
Session history and accuracy tracking over time.
Works for any subject, not just vocabulary.
For Schools
Teachers assign Study Decks with only the terms. Students build the study material themselves — writing definitions and explanations. This act of construction is itself a powerful learning exercise. Students know: if I prepare these flashcards and prove understanding, I am well prepared for exams.
Progress — Every Word, Every Session, Tracked
Lexiage makes vocabulary development visible and quantifiable. For parents, reassurance. For teachers, data. For students, proof of progress.
Learning Modes
Every word attempted, every mode completed, every accuracy rate — with granular detail on mastered and corrected words.
Word Workshop
Every sentence submitted, every AI evaluation, progress toward the 3-sentence mastery per word.
Study Decks
Every study session, every self-rating, accuracy trends over time.
Multi-Language Support
Lexiage supports vocabulary development in dozens of languages — with independent progression tracking for each one.
System Wordlists
Full 18-level curated curricula with frequency-based word selection, CEFR alignment, and academic vocabulary integration.
