Full description

FillIn helps you actually remember words - not just see them once and forget. Instead of flipping flashcards, you complete real sentences with the missing word. Active recall plus spaced repetition means every word comes back right before you'd forget it. WHY FILLIN • Fill-in-the-blank exercises - type the word in a real sentence, not in isolation • Spaced repetition (SM-2) - reviews scheduled exactly when you need them • Daily goals - a clear target of correct answers and due reviews each day • Progress you can see - success rate per word, streaks, and what you've learned • AI-generated exercises - generate a prompt, use any AI assistant, and import personalized practice BUILT-IN VOCABULARY Curated word sets for several language pairs (English, Polish, Spanish, German, French) get you started immediately - no setup, no account. PRIVATE BY DESIGN Everything stays on your device. No tracking, no ads, no account required. Start filling in the blanks and watch your vocabulary stick.
