I'll teach you to read Japanese, Korean or Russian, one letter at a time.

N row, E column.
And much more than flashcards: tap countries on the map, turn a 3D skeleton, listen to Morse code, watch a request cross the internet. The whole library is free, with no ads, and Voyelle brings each card back right when you need it.
Free, no credit card. In your browser, on desktop and on your phone.
Made by Voyelle from each subject's syllabus, and free. There is nothing to build: you pick, you study. Teachers are the ones who create decks, for their own classes.
Missing a subject? Request it in the app
Every subject gets the format that suits it. Tap, listen, turn, put in order: handling things is how they stick.
Countries of the world, capitals, flags, French départements, US states: Voyelle names a place and you tap it on the map. Or it lights one up and you name it.
199 bones to turn, name or point at, from the skull to the phalanges.
Hiragana, katakana, Hangul, Cyrillic, Greek, the NATO alphabet, and Morse code, which you hear before you read it.
All 118 elements in their place: symbols, atomic numbers, families, electron configurations. You learn where an element sits, and why it sits there.
Key dates, presidents, geological time: you slide each event into place, and the timeline reads level by level.
Networks, protocols, web services: watch a request travel from the browser to the server step by step, then find the part that is failing.
Every idea comes back in harder and harder formats: first you recognise it among others, then you recall it from memory, and finally you produce it yourself.
After a missed answer, “Understand” opens the explanation, the Explorer centred on what you were looking for and the cards linked to it. Then your session picks up where it was.
No questions, no clock: roam the world, France or the United States on the map, turn the skeleton, open the periodic table, read a timeline level by level, play a protocol step by step or build an architecture in the sandbox.
A goal, the decks in the right order, each step opening once the one before is mastered, and a badge at the end. First path: “Designing a web service”, 41 decks in 7 steps.
See the pathVoyelle takes care of when. All you do is open the app for a few minutes a day.
Voyelle shows you each card right when you were about to forget it, and learns your pace as you go. Less reviewing, more remembering.
Missed a few days? No wall of overdue cards. You get a normal session back, and the rest is spread over the days ahead.
Every topic of your course or exam has its own ring that fills up as you master it. You always know where you stand and what is left to work on.
Each day Voyelle picks the cards due across all your decks and mixes them. All you do is open the app.
Every deck follows its subject's syllabus topic by topic, and never reuses real exam questions.
Mistakes are never punished. The card simply comes back sooner, which is how it sticks.
Every review earns experience. A streak freeze keeps your streak alive on a day you can't study.
A readiness score tells you when you are ready for your test, your finals or your exam.
No ads and no data sales. Your attention stays on what you are learning.
Rings that fill up topic by topic, a streak to keep alive, a league to climb every week. Coming back each day becomes something you look forward to.
Five timed rounds, each harder than the last: a map, the periodic table, the skeleton, a timeline and Morse code. One try, a score out of 1000, a grid to share without giving the answers away, and a streak of its own that never touches your study streak.
Karti hosts, referees and hands out the titles. Everyone plays on their own phone: team quizzes, secret roles, miming, places to tap at full speed. Forfeits go before Karti's Tribunal, and the next day the cards you missed are waiting in your reviews.

Those in the library: geography, anatomy, alphabets and languages, chemistry, history, maths, law, economics, computing, certifications… It grows with what members ask for: if a subject is missing, request it from the app.
Yes. The free plan gives you the whole library, unlimited reviews, today's session and 1 targeted session a day, the Explorer, learning paths, the daily challenge and the Apéro, with no ads. Voyelle Plus puts you in control of your reviews, for €9.99 a month or €59.90 a year.
No. The library's decks are made by Voyelle, and only teachers create decks, for their classes. There is nothing for you to prepare: pick a deck and start studying.
Yes, a free one that takes seconds to create. It keeps your decks and your progress in sync across your devices. The card on this page is the one thing you can play without an account, so you can get a feel for it first.
They are written from the official outline of their subject or certification, then checked before joining the library. They never reuse real exam questions, which candidates agree not to disclose.
Nothing bad happens. When you come back, Voyelle gives you a normal-sized session, starting with what you are most likely to forget, and spreads the rest over the following days. A streak freeze can also keep your streak intact.
No. Voyelle helps you remember what you learn, and keep it for a long time. It works alongside your classes, the official documentation and hands-on practice, not instead of them.
