Free Flashcards with Spaced Repetition

Pick a language, see a word, try to recall its meaning, then grade yourself. Cards you find hard return sooner; cards you know move further down the pile.

Tool

Spaced-repetition flashcards

Based on FrequencyWords (CC BY-SA 4.0). Word selection from FrequencyWords (CC BY-SA 4.0); meanings checked against each language's reference dictionary. Audio is generated in your browser.

How it works

Each language has a starter deck of common beginner words. The tool uses a simple Leitner system: every card sits in a box numbered 1 to 5.

A new card starts in box 1.
Press Got it and the card moves up a box; reach box 5 and it counts as mastered.
Press Again and the card drops back to box 1 and returns later in the same session.

Cards in lower boxes are shown first, so your weakest words get the most practice. Your box numbers are stored in your browser’s localStorage, so you can close the tab and pick up where you left off on the same device.

Where the words come from

Which words count as “common” is taken from the open FrequencyWords project (word lists built from film and TV subtitles, licensed CC BY-SA 4.0). The English meanings are everyday dictionary facts, checked against each language’s reference (for example the Cambridge Dictionary for English and the Real Academia Española for Spanish). Pronunciation is spoken by your browser’s built-in voices (the Web Speech API) — we do not use recordings of named people.

Limits of this tool

The decks are beginner-sized starter sets, not a full dictionary; they are a base to build on, not a complete course.
Progress lives on one device and one browser; clearing site data resets it, and it does not sync across devices.
Browser voices vary, and a few languages may have no installed voice, in which case the Listen button is hidden.
