How it works

Three simple steps to effective memorization

1

Create a deck

Add words manually, import from a file, snap a photo, or highlight words directly from any text

2

Study every day

The SM-2 algorithm picks the optimal moment to review each card

3

Remember forever

With each review, the interval grows — from minutes to months

Everything you need to remember

AI-powered import

Pro

Upload any document — text, PDF, CSV, web link, or photos of textbook pages — and let AI analyze it and generate flashcards for you. Snap a photo and the app extracts text automatically.

Spaced repetition

The SM-2 algorithm detects when you're about to forget a word and shows it just in time. 5x more effective than cramming.

Works offline

Study on the subway, a plane, or in the countryside — no internet needed. Progress syncs when you're back online.

Words from text

Paste any text, highlight unfamiliar words — the app automatically adds translations and transcriptions.

Comprehension checkpoints

Pro

Periodically read AI-generated texts based on your deck vocabulary. See which words you understood and which ones to review.

Like a real app

Install on your phone's home screen. Works like a native app — no App Store or Google Play required.
