Lexori is a vocabulary trainer. Every word comes with audio, an example and a translation into your language, most with a picture too, and each one returns right before you are likely to forget it. A few minutes a day is enough.
No sign-up form: your teacher (or the Lexori team) creates your account.
What is Lexori
You don’t decide what to repeat and when. You answer a few cards a day, and Lexori takes care of the rest.
A translation into your language, an everyday example, a definition, clear spoken audio and, for most words, a picture. Not a bare list of pairs.
Spaced repetition plans every review for you. Words you know well show up rarely, shaky ones come back until they hold.
Open Today, go through the cards that are ready, and you’re done. A streak and a year of practice keep you going.

How it works
Same routine every day, on a laptop or a phone.
The number on the button is how many cards are ready right now. Nothing more to plan: when they are done, you are done. Once some words are solid, a yellow Recall button appears under it (more on that below).
The word plays by itself; press the speaker to hear it again. Try to recall the meaning before you look: say it out loud or think it through. The bar on top shows how far you are in the session.
Press Reveal answer (or Space). The example plays by itself. Compare with what you said: the translation, the picture, the example and the definition.
Again, Hard, Good or Easy. This is the only decision you make, and it sets when the word comes back. Here is how to choose.
The back of a card
When you reveal an answer, you don’t just see a translation. Each card is built so the word has something to hold on to.
The word
Exactly as you will meet it, with an article or "to" where it belongs. The speaker plays it.
Translation
Into the language you chose, with several meanings when the word has them. You can also switch translations off and learn from the picture and the definition alone.
Picture
An illustration of the meaning. Pictures stick in memory faster than lists.
Example
A short everyday phrase with the word, its own audio and its translation.
Definition
A plain explanation in the language you are learning, to start thinking in it.
Report and note
The flag reports a mistake in the word. The page icon keeps your own note on the card.
Card info
Where the word stands for you: its stage, how many times you have reviewed it and how firmly it is held.
Your answer
Four buttons, each with the time until the next review under it. Read below which one to press.
Undo
Takes back the last answer if you pressed the wrong button.
Recall cards
Recognising a word is half of knowing it. Once a word holds for about ten days, Lexori also asks it the other way round: you see the meaning and produce the word yourself.
Progress
The Progress tab shows how regular you are and how well the words hold.
My cards, the second tab, lists every word you study with a search box and a filter by stage.
Several languages, any device
Learning English and Portuguese at once? Each language gets its own deck, its own settings and its own card on Today. The streak counts them all.

For teachers
Create accounts for your students, give them the words from each lesson in a minute, and see who actually practises between classes.
See the whole class at a glance
Who practised today, how many reviews were done, how many cards are waiting, and who has not practised for a week. Each student has a private note only you can see.
Give words by pasting a list
Paste the words from today’s lesson. Lexori matches them with the dictionary and the student’s deck, and you choose for each: Learn, Known or Skip.
A dictionary that fills itself
A word nobody has added yet is created for you: translations, an example, a definition and audio. Pictures are added to the dictionary over time.
Review together in class
Review as student opens the student’s due cards, so you can go through them side by side in class. The answers count as the student’s own reviews. Progress shows their streak and accuracy.
Fix what is wrong
Spotted a weak translation or example? Suggest a correction from the dictionary; unless you are a trusted editor, it is checked before it reaches every learner.
Teachers can learn too. The Learn | Teach switch in the header opens your own deck, with the same cards and the same daily routine as your students.
Questions
There is no public sign-up. If you study with a teacher, they create your account and give you a username and password. If you want to learn on your own, or to teach with Lexori, the Lexori team creates the account for you.
Usually 5 to 15 minutes a day. The Today screen shows how many cards are ready; when you have gone through them, you are done for the day.
Nothing is lost. The cards simply wait, and the pile is a little bigger when you come back. Do it in a couple of sessions if it is too much at once. Only your streak starts over.
That is the point of spaced repetition. Every answer updates how firmly you know the word, and Lexori brings it back right before you are likely to forget it. Shaky words come back often, solid ones rarely.
New: you have not seen the word yet. Learning: its first short steps, minutes apart. Review: you know it, and it comes back at growing intervals. Relearning: you forgot it and it is going through the short steps again.
Once a word holds for about ten days, Lexori also asks it the other way round: you see the translation, the picture, the example and the definition with the word blanked out, and produce the word yourself. They have their own Recall button on Today, and you can switch them off with the Recall option in the language settings.
Right now English and European Portuguese, with translations into Russian or Ukrainian (and into English for Portuguese). More languages are on the way. One account can learn several languages; each has its own deck and settings.
If your teacher allows it, or if you learn on your own, yes: the Add a word box on Today adds a word to your deck, and Add many takes a whole list. Anything missing from the dictionary is created for you.
Yes. Open lexori.app in the browser and add it to the home screen: on iPhone, Safari → Share → Add to Home Screen; on Android, Chrome → ⋮ → Add to Home screen. It then opens full screen like an app.
Press the flag on the card and describe what is wrong. Reports go to the team that looks after the dictionary, and the fix reaches everyone who studies the word.
