Sentences
Write it in Serbian
Are you Ana?
Why you still can't write a simple message
What most apps train
What speaking requires
And when you miss
The app knows which word and which rule broke, and sends exactly that back into repetition. Not the sentence, not the lesson: the one thing you got wrong.
You can do years of the first without once doing the second. Peroglot only trains the second.
How a lesson works
Every lesson has the same shape. You read one rule, learn the words it needs, then you write.
A structure you can't cheat, so you can't fool yourself.
The steps run in order and none can be skipped. You cannot reach the text before you can write the sentences.
Courses
Read from the published courses when the site is built. A level appears here the day it is published, never before.

Sentences
Write it in Serbian
You are not teachers, you are students.
negated 'to be' (plural you) + plural noun, then pronoun + 'to be' + plural noun
The sentence step, up close
You get a sentence in your language and write it in Serbian. The check reads every word, marks the one that broke and shows the rule behind it.
Every valid answer is accepted.
Word order, synonyms, a dropped pronoun: each sentence carries all of its accepted forms. This one takes 32.
Typos are forgiven, and flagged.
A slipped letter still counts as correct. A wrong ending never does; that is where the grammar lives.
Every miss lowers something specific.
A wrong form halves the level of that word or that rule, not of the whole sentence. Your weak spots come back sooner.
Everything decays
Every word, every form and every rule has a level from 1 to 10. A correct answer when it is due moves it up one, and the gap before the next time grows from ten minutes to two weeks, then keeps doubling. A miss halves the level. Nothing is ever wiped.
You can see the level of everything you know, at any time.

Two quiet guarantees
You'll never meet a word you haven't learned.
Texts, dialogues and sentences are built only from words the course has already taught you. No guessing from context, no dictionary in the other hand.
Every explanation is in your language, at every level.
The grammar is written for English speakers, not translated from a generic course. A German and a Russian learner get different explanations of the same Serbian rule.
Your first 10 lessons are free, in any course. No card needed.
Words as cards
Memory hooks, not illustrations. Each card is a picture, a voice, the translation and a sentence you have already met.

Finish a lesson step and you earn a feather. When a level is about to halve over something you are sure you knew, spend one to keep it.

From the founder
I have been learning languages for most of my life, and every app I tried stopped at recognition: years of tapping tiles, and still not one message written from scratch.
I needed Serbian, nothing serious existed, so I built the course I wanted: one that makes you write and tells you exactly what went wrong. It is hard on purpose.
Lev, founder
Yes. Lessons, pictures and audio are downloaded to your phone as you reach them, and a lesson that is on the phone works with no connection.
Nothing is deleted or reset for being away. Everything that came due is waiting, you work through it at your own pace, and a level only ever drops when you answer wrong.
As long as your mistakes make it. A lesson is one rule, about 25 words, 25 sentences to write, a text and a dialogue. The repetition step depends on what is due.
Everything you learned stays. You can keep repeating those rules and words for free, for as long as you like. New lessons and new words need a subscription. The 10 free lessons count per account, in any mix of courses.
Serbian today. More pairs are being written. This page lists exactly what is published, never more. Over time, the plan is every European language. Which one comes next is partly up to you: the next-language form counts toward the choice.
