One app for every new word.
Type a word from a book, a show or a conversation. Repi fills in the card and brings it back right before you'd forget it.
Free to start. No account needed.
Quiero aprovechar el buen tiempo.
Add a word
Type it in. Repi adds the translation, transcription and an example sentence.
Review today's cards
Two to five minutes on the bus or in a queue. You only see the words that are due.
Keep it for good
Each time you remember a word, Repi waits longer before showing it again.
Type one word. Get a full card.
Fill in with AI adds the translation, base form, transcription and example sentences. Edit any field before you save.
Four ways to practice each word
Repi switches exercises so you recognize the word, recall it, spell it and use it.
- Remember this word?
- Translate the word
- Complete the sentence
- Make a sentence
Write your own sentence. AI checks it.
Use the word in a sentence of your own. Repi points out the mistake and shows the fix, like 'muchos libros' instead of 'muchos libro'.
Learning more than one language?
Keep Spanish, French and German side by side. Switch languages from Home, and each one keeps its own cards.
Do I need an account?
No. You start as a guest with the full app. Sign in with Apple, Google or email later to back up your words or move them to a new phone.
What is free and what is in Premium?
Free gives you up to 50 cards and 10 AI fill-ins a day. Premium removes both limits. Decks, sync and all four exercises are free for everyone.
How much time does it take?
Two to five minutes a day for most people. Set the maximum number of cards per day in Settings; the default is 50.
What if AI gets something wrong?
Every field stays editable. You can also skip AI and type the card yourself.
Does it work offline?
Yes. Reviews, stats and adding cards by hand work without a connection. AI and sync pick up when you're back online.
