Leka

Leka is a web-based flashcard app designed for language learners who want to streamline their study routine. It combines translation, spaced repetition flashcards using the FSRS algorithm, and integrated verb conjugation tables in one workflow. Users can type or paste text, which is automatically translated and converted into study cards. The app supports Spanish, Italian, German, French, Portuguese, and Dutch, with offline functionality as a progressive web app.

The maker built Leka with Lovable to solve their own language learning workflow after moving to Spain. It's free to start with a premium upgrade available, and upcoming features include different study modes, voice-to-text, and image-based translation.
