Vocabulary flashcards that still remember the word next month

Why word lists fade and spaced words stay

A list of twenty words learned on Monday is half gone by Friday unless each word comes back at the right moment. Cogni's spaced repetition tracks every word separately: the ones you know drift weeks ahead, the ones you keep missing return tomorrow, and the daily queue stays small enough to finish on the way to work.

Made for vocabulary

• ✓Reverse a deck to study word → meaning and meaning → word with one switch
• ✓Text-to-speech in English, Spanish, French, German, Italian, Portuguese, Ukrainian, Russian, Japanese, Chinese, Korean and Arabic
• ✓Cloze cards for grammar: hide the verb ending or the preposition
• ✓Images and audio on cards for words you want to hear and see

From reading to cards

Paste an article, a chapter or your class notes and let the AI generator write vocabulary cards from it: word, meaning, example sentence. Or type a topic, such as "ordering food in Spanish", and start from a generated deck. Every card is a draft you can edit.

Ready-made decks and your Anki decks

The library includes vocabulary decks for the most studied languages and exam word lists, and shared Anki decks such as frequency lists import as .apkg files with their audio.

Ten minutes a day, anywhere

The mobile apps work offline and the web app picks up where you left off. Streaks and a daily due count keep the habit small enough to keep, which is the only kind of language habit that survives past January.
