How it Works

From text to flashcards
in seconds

No more manual card creation. Just paste your content and let AI do the work.

1

Paste any text

Article, news story, book excerpt, lecture transcript — anything you're reading or studying works.

2

AI extracts vocabulary

Claude AI identifies key words at B1–C1 level and instantly fills in meanings, IPA pronunciation, and example sentences.

3

Study smart

Cards are scheduled by spaced repetition. Review exactly when you're about to forget — for maximum retention.

4

Track progress

Watch words move from "New" to "Mastered". Streaks, heatmaps, and accuracy stats keep you motivated.

Each mode targets a different aspect of recall — from recognition to active production.

Spaced Repetition System

Cardify tracks every word through 4 learning levels. The algorithm schedules each card precisely when your memory is fading — so you spend more time on hard words and less on what you already know.

The result: 2–5× better retention compared to passive reading or traditional flashcard apps.
