You bring the words. It handles the remembering.
Opisanoja is for people who already know which words they need. There are no preset courses — add words as you meet them, and spaced repetition brings each one back at the moment you are about to forget it.
Free to start. No account required.
What it does
Your words, not a syllabus
A textbook, an exam, a new country, a book you are still fighting through — the words that matter are yours, not a course author's.
Spaced repetition
The engine tracks how well you knew each item and schedules the next review. What you clearly know stops taking up your time.
Works offline
Your vocabulary lives on the device, so you can train on a plane or underground. An account is optional — sign in only for backup and sync.
Listen while you walk
Listening training reads your phrases and their translations aloud, and keeps playing in the background with the screen off.
Streaks and goals
Daily goals, streaks and per-word progress: what is new, what you are learning, and what has moved into long-term review.
Phrases, not just words
Store whole expressions with usage examples, tag them however you like, and attach an image when a picture sticks better than a translation.
Nine ways to train
Recognising a word is not the same as being able to produce it, so the same vocabulary is approached from every angle.
- Word to translation
- Translation to word
- Flashcards, native to foreign
- Flashcards, foreign to native
- Word match
- Type the translation
- Sprint
