See a word you don't know. Save it in a second. Remember it. Use it.
Vocab is made for people preparing for TOEIC, IELTS or TOEFL, and for anyone who works in English. AI fills in the meaning, pronunciation and examples from work, exam and reading situations; spaced repetition keeps the word in your head; and sentence practice checks that you can really use it.
The web app is free to sign up for (100 words). The iOS app is coming to the App Store.
Three steps from “what does that mean?” to using it
No note-taking first, no hunting for examples.
Save it in a second
Type a word and it is saved at once, even offline. Misspelled words are never saved, and you get a hint of what you may have meant.
AI fills in the rest
Meaning, IPA and audio, plus examples from work, exam and reading situations, common collocations and look-alike words. Traditional Chinese is optional.
Review and actually use it
Spaced repetition (FSRS) schedules the reviews and fill-in-the-blank recall makes it stick; then write a sentence and let AI check it.
Built for remembering and using
Every feature serves one goal: turning words you have seen into words you can use.
Real-situation examples
Each word comes with work, exam, reading and everyday examples, not just a one-line definition.
Spaced repetition (FSRS)
A modern scheduling algorithm so you only review the words you are about to forget.
Fill-in recall
Read an example and type the missing word. A better test than flipping cards.

FAQ
Can I use it now?
Yes. The web app at vocab.jimmy-tools.com is open for free sign-up; the iOS app is coming to the App Store.
Is my data safe?
Your words live on your device and are synced to the cloud once you sign in. We do not sell data; see the privacy policy for details.
Are misspelled words saved?
No. Spelling is checked first, a likely typo is not saved and a suggestion is shown; if you are sure it is right, you can ask the AI to double-check.
Is there a limit on AI lookups?
Free gets 50 a day; words that already have a shared cached entry do not count. Pro is unlimited.
Can I import my existing words?
Yes. Settings has “Import words” for CSV files and Anki text exports. Only correctly spelled words are added; the rest are listed for you to check.
