Vocabulary you
actually remember
Build a space for the language you’re learning, and let spaced repetition tell you exactly when to review each word, not too soon, not too late.
This is how words actually move, from first glance to lasting memory, no more cramming the night before, just remembering.
Discovery a new word starts here. Answer it once, and we decide what happens next.
Practicing the word moves here after you answer right a few times in Discovery. Answer well, and you wait longer next time. Answer wrong, and it goes back to Discovery.
Mastered recalled reliably across a long stretch of time, the widest gaps between reviews of any circle.
Why wobbles works
Create your space with a language pair
Learn English, French, German, or Spanish, translated into any of those or into Arabic, Chinese, Farsi or Portuguese.
Spaced repetition that adapts
Every word moves through three circles based on how well you actually remember it.
Start from a ready-made bank
Import ready-made vocabulary for your language pair, or build your own from scratch.
Frequently asked questions
What languages can I learn?
English, French, German, or Spanish, translated into any of those or into Arabic, Chinese, Farsi or Portuguese.
How does spaced repetition work here?
Every word moves through three circles, Discovery, Practicing, and Mastered, based on how well you actually remember it. Correct answers space reviews further apart; wrong answers bring a word back sooner.
What happens if I get a word wrong?
One wrong answer in Practicing sends a word back to Discovery. A Mastered word gets more benefit of the doubt: it takes two wrong answers in a row before it drops down to Practicing.
Do I need my own word list?
No. Import a ready-made vocabulary bank for your language pair, or build your own list from scratch.
Is it free to start?
Yes, creating a space and starting to learn is free.
