Overview
Most vocabulary apps hand you a list somebody else wrote. The words are real English, but they are not your words — not the terms in your chapters, not the vocabulary your paper tests. You end up learning words you will never be asked about while the ones on your syllabus stay fuzzy.
LexiGenome starts from your own material. Words are mined from the chapters you study, explained in language you already think in, drilled in six different ways, and scheduled so you meet each one again exactly when you were about to forget it.
Where the words come from
Words come from the chapters in your board, class and subjects — the terminology that actually appears in what you are being taught. A Class 10 Biology chapter yields the terms that chapter examines. A competitive paper yields the vocabulary that paper tests.
This is the difference that matters. “Ubiquitous” is a fine word; it is not on your Biology paper. “Transpiration” is.
Mining a chapter
In Decks, use Mine a chapter: pick the subject and the chapter, and the words worth knowing are pulled out of it into a deck you can study.
This is the fastest way to prepare for a specific paper — mine the chapters on the syllabus, and you have precisely the vocabulary that paper can ask about, with nothing extra.
Adding your own words
You can also add a word by hand — Add a word, type it (for example resilient), and optionally give a sentence or topic for context.
Use this for words from a book, a newspaper, a paper that is not on the platform, or anything you keep tripping over.
Explained in your language
A definition you have to decode twice teaches you nothing. Words are explained bilingually, so the meaning lands in the language you think in before you are asked to produce it in English.
This matters most for exactly the students who need vocabulary help most — those studying in English in a school where English is not the language of the corridor. An English-only definition quietly filters out the people it was supposed to serve.
The six practice modes
“Knowing a word” is several different skills, and each mode trains a different one. Meeting the same word in more than one mode is what turns recognition into use.
| Mode | What happens | Skill it trains |
|---|---|---|
| Recall | Flip-card spaced repetition. | Can you produce the meaning at all? |
| Cloze | Fill the blank in a real sentence. | Does it fit in context — the hardest part of using a word correctly. |
| Sentence Forge | Write your own sentence with it; the AI marks whether you actually used it correctly. | Production. The hardest mode and the one that proves you own the word. |
| Multiple Choice | Pick the right meaning from options. | Fast recognition under time pressure. |
| Listen & Spell | Hear the word, spell it. | The sound-to-spelling link that dictation and listening comprehension depend on. |
| Synonym Sort | Sort synonyms from antonyms. | The shape most competitive papers actually test. |
Which mode to use when
- New words → Recall, then Multiple Choice. Get recognition first; production comes later.
- Words you recognise but cannot use → Cloze, then Sentence Forge. This is the most common plateau and the one that costs marks in writing.
- Spelling mistakes in exams → Listen & Spell.
- Competitive vocabulary sections → Synonym Sort and Multiple Choice, for speed.
- The day before a paper → Recall only. It is the fastest sweep and the least likely to dent your confidence.
How the scheduling works
Reviews are scheduled with FSRS, a modern spaced-repetition scheduler. Rather than moving a card along fixed intervals, it models two things about you and each individual word:
- Stability — how durable your memory of that word currently is; how long it will survive without a review.
- Difficulty — how hard you personally find that word, which is not the same as how hard it is in general.
From those it picks the moment when reviewing is most useful: late enough that the retrieval is effortful (which is what strengthens memory) but early enough that you have not lost it.
In practice: words you find easy disappear for weeks, words you keep missing come back tomorrow, and your daily queue stays small because nothing is shown before it needs to be.
The Today queue
Today holds the words actually due right now. This is the daily habit, and it is usually a few minutes.
If you want to do more, add words or mine another chapter rather than re-reviewing words that are already secure.
Asking about a word
Any word has a tutor attached — ask a question about it in your own words and get an answer about that specific word. Useful for the questions a definition does not answer: “when would I use this instead of…”, “is this formal?”, “why is this wrong in my sentence?”
The Word Genome map
Your vocabulary drawn as a map rather than a number: which clusters of your syllabus you have covered, which are thin, and which words are drifting toward being forgotten.
It is the fastest way to notice that you have learned every term in one chapter and none in another — the kind of imbalance that a total word count hides completely.
League and streak
Practice earns XP toward your streak and weekly league, the same system the rest of the platform uses — see Streak, XP & weekly league. The League tab shows where you sit this week.
A sensible routine
- Mine the chapters you are currently studying into decks.
- Clear the Today queue every day. A few minutes, not a session.
- Once a week, run Sentence Forge on words you recognise but never use.
- Before a paper, sweep the relevant deck in Recall only.
- Check the Word Genome occasionally for a chapter you have neglected.
Common questions
Does it replace flashcards?
No. Flashcards cover chapter concepts, formulas and facts. This covers words — meaning, spelling, usage and near-misses. Different material, different failure modes.
Why did an easy word come back so soon?
Either you rated it as hard, or it is newly added. Stability builds over several successful reviews; a word seen once is not yet secure however easy it felt.
How long should a session be?
Finish the Today queue. That is the whole habit, and it works because it is small enough to do on a bad day.
Can I study one deck on its own?
Yes — open the deck and use Study deck. Useful when one paper is close and the rest can wait.
I missed a week. Is my progress gone?
No. The overdue words come back first and the queue is larger for a few days, then settles. Nothing is reset for missing time.
