About this app

Learn words that actually stick.

Slovira turns the words you meet every day into long-term memory — with spaced repetition, smart flashcards, and AI-assisted cards. In 30+ European languages, in both directions.

— Everything you need to remember more —

• Spaced repetition — Proven SM-2 scheduling shows each word right before you'd forget it — so it moves into long-term memory.
• AI-assisted cards — Tap ✨ and AI fills in the translation, pronunciation, and a natural example sentence.
• Both directions — Learn a new language from your own — or flip it and go the other way — with a pronunciation hint written in your own script. Cards flip to match.
• Synced everywhere — Your words and progress follow you across phone, desktop, and browser — just sign in with Google.
• Capture anywhere — Save a new word from any app or webpage with the share menu and the browser extension.
• Stay motivated — XP, streaks, achievements, and a stats heatmap keep you coming back every day.

— How it works —

1. Capture a word — See a word you don't know? Add it in a tap — from the app, the share menu, or the browser extension.
2. Review smartly — Slovira schedules each card with spaced repetition, so you study only what you're about to forget.
3. Watch it stick — Words move into long-term memory, your streak grows — and the language you're learning grows with it.
