More than a notebook
A vocabulary notebook that writes itself, tests you, and makes sure you never forget a word.
AI fills your notebook
Type a topic — "TOEIC vocabulary," "medical terminology," "Spanish verbs" — and Flashi generates a complete set of vocabulary cards with definitions and examples.
Spaced repetition schedules reviews
A paper notebook can't tell you which words to review today. Flashi uses SM-2 spacing to surface words right before you forget them.
Quiz yourself on vocabulary
Test recall after your review sessions so you can spot weak words before they disappear from memory.
Import existing vocabulary
Already have vocabulary lists in Anki or CSV? Import them into Flashi and continue studying with spaced repetition on iPhone.
Common questions
Is Flashi better than a paper vocabulary notebook?
For memorization, yes. A paper notebook stores words but doesn't help you review them at the right time. Flashi uses spaced repetition to schedule reviews, plus AI generation and quiz mode that paper can't offer.
Can I use Flashi as a vocabulary notebook for any language?
Yes. Generate vocabulary decks for English, Japanese, Spanish, French, German, Korean, and more. Each deck includes definitions and can be reviewed with spaced repetition.
How is Flashi different from Anki?
Flashi includes AI deck generation, import, and quiz mode — all free. Anki on iOS costs $24.99 and requires manual card creation. Both use spaced repetition.
Is Flashi free?
Yes. Flashi is free to download. An optional Flashi Pro subscription unlocks unlimited AI generation and more. No account required.
