A schedule that adapts
FSRS-5 predicts recall for every card separately and picks the day when a repetition is worth the most. Easy words leave for months, hard ones stay close.
Spaced repetition on FSRS-5
Learn a word once – and keep it
Wortly works out the day you are about to forget a word and shows it exactly then. Ten minutes in the morning instead of an hour of cramming that leaks by Friday.

17 languages to learn
Gender, articles, romanisation and the voice for audio come from the language itself, so a Japanese word is not asked for an article it does not have.

What is inside
Not a course and not a game – a tool for the part of a language that has to be learned by heart anyway.
One word, several cards
Recognising Haus → house and typing it from memory are different skills with different forgetting curves. Each method keeps its own state and its own date.
A dictionary of your own
Add a word in two taps or paste a whole list – it is split into word, translation and example for you. Every translation stays yours to edit.
Modules to share
Collect a word set and keep it to yourself, hand it over by a secret link or publish it. Someone else’s module installs into your dictionary in one tap.
Statistics without flattery
Streak, vocabulary maturity, retention and the forecast of the load for the coming days – the plan, not only the past.
Free and quiet
No subscription, no ads, no limit on words and no notifications begging for a streak. Email, password, and you are in.
Three steps to the first session
-
Pick a language and a pace
Onboarding asks for your native language, the one you are learning and how many words a day you are ready to take.
-
Fill the dictionary
Type the words in, paste a list from a lesson, or install a ready module from the library.
-
Study when it asks
Today’s queue is already waiting on the home screen. Every answer moves the date of the next show.
Nine ways to practise one word
Switch off the ones you do not need – their cards pause and keep the progress they had.
- Recognition Word → translation
- Recall Translation → word, in your head
- Multiple choice Four options, a soft start
- Typing Type it exactly, article included
- Listening Hear it, name the meaning
- Fill the gap The gap in a sentence
- Speaking soon Say it out loud
- Matching soon Match the pairs
- Word forms soon Plural, past, participle
Why intervals beat cramming
Memory drops fastest right after learning. A repetition on the edge of forgetting flattens the curve and stretches the next interval – from ten minutes to months.
- The interval is counted from the real time between shows, not from an abstract level
- A wrong answer brings the word back in the same session
- A missed day costs a date, not the progress of a card
Questions
Is it really free?
Yes – every method, an unlimited dictionary and the full statistics. There is no paid plan.
What can I learn, and in which language?
17 languages to learn; the interface speaks English, Ukrainian, Russian and German.
How is this different from ordinary flashcards?
A word becomes several cards, one per method, and each has a schedule of its own. A word you recognise but cannot spell keeps coming back until you can.
How much time does a day take?
You set the daily goal yourself; twenty words take about ten minutes.
Ten minutes today are worth more than three hours on Sunday
Registration takes half a minute, and the first session starts right after it.
