Built for serious learners. AI-native from day one.

Own the words you meet.

Vocabul turns any word you encounter — in a book, a meeting, a song — into a rich, memorable card. Tap once. AI does the dictionary work. You keep the vocabulary.

A vocabulary tool, redrawn around AI.

Not a deck. Not a curriculum. Your library — built from the words you actually meet, with AI doing the dictionary work in the background.

Novel

in the ephemeral glow of evening

Capture once. Own forever.

Your library is yours. No publisher curriculum, no community deck — just the words you chose to keep, in a vault you control.

ephemeral,adj.lasting for a very short time.

More than a dictionary entry.

Every Card carries a definition, CEFR level, part of speech, collocations, examples and IPA pronunciation — written for the way you read.

petrichor
/ˈpet.rɪ.kɔːr/
C2
noun
the petrichor of summera faint petrichor

Built around AI from day one.

Cards stream in field by field as you watch. Inflections collapse to the right lemma. Duplicates surface before you save them.

Coming soon
You saved 'petrichor' last Tuesday. Use it in a sentence.
Nice — and notice how 'after rain' is almost redundant. Try once without it?

Your coach, in your pocket. Coming soon.

An AI tutor that quizzes you on your own Cards, conversationally — not on a generic word list. Shipping in the Learn tab.

I read novels in English and used to lose every word the next day. With Vocabul I look it up once, and the Card waits for me when I'm ready.

AI-native, where it counts.

Four moments where AI does the heavy lifting — so the time you spend in Vocabul goes into learning, not card-making.

Your vocabulary, compounding.

The longer you use Vocabul, the more your library becomes yours. We don't ship pre-made word lists. We sharpen the one only you could build.

Week 120Your first Cards. Each one a full definition — the dictionary work already done.

Start. The first 20 Cards.

Capture the words you meet today. Tap once and a complete Card streams back — definition, level, examples, pronunciation. No deck to manage.

Month 3500+Vocabul knows your level, your topics, your inflection patterns. Duplicates caught automatically.

Sharpen. The library knows you.

By the third month your library has weight. Inflections collapse to the right lemma. Near-synonyms surface before you save a duplicate. Search finds the word you half-remember.

Year 1Yours.A vault of words you met, you chose, you learned. Searchable, exportable, yours.

Keep. A vault that is yours.

After a year, the library is a fingerprint — only you could have built it. Searchable, exportable, portable. Not rented from a publisher.

The learners who already moved.

Independent readers, exam candidates, working professionals, and tutors — each naming the part of Vocabul that earned the switch.

I read novels in English and used to lose every word. Now I tap, get a real card, and actually keep them.

The CEFR tags are why I switched from Quizlet. I know exactly which words are at my level — and which to push past it.

English is my work language. Vocabul catches the idioms my coworkers throw at me and quietly turns them into cards I review on the train.

I make a Set, share it with my students, and we actually talk about the words in class instead of writing them on the board.
