Learn languages from your own mistakes
You read short texts with the sound and the translation under every sentence, write them from memory, and talk with your tutor whenever you like. Whatever you get wrong comes back in your next text until you stop getting it wrong.

One text, three steps
In the app they're called Day 1, Day 2 and Day 3, but you take them at your own pace: on the same day or on different days. Here's the same sentence in all three.
Day 1. You understand it.
You read and listen to the text with the sound and the translation of every sentence. Don't know a word? Tap it to see what it means and how it sounds, and save it to your lexicon.
Cada mañana me preparo una taza de té.
ˈka.da ma.ˈɲa.na me pɾe.ˈpa.ɾo ˈu.na ˈta.θa de te
Every morning I make myself a cup of tea.
Day 2. You write it from memory.
You see the sentence in English and write it in the language you're learning, without looking. That's where your real mistakes show up.
Every morning I make myself a cup of tea.
Cada mañana me preparo
ununacopataza de té.Taza is feminine, so it's una.
Day 3. You lock it in.
You see what tripped you up in that text, grouped by rule and with the why, and save the words you missed to your lexicon. If you like, you go over it with your tutor or practice your pronunciation.
What tripped you up in this text

What it's based on: five pillars of the science of learning
Five principles backed by research on how languages are learned.
Comprehensible input
Texts at your level about what interests you, that you understand almost entirely. A language is acquired by understanding it.
Active recall
You write the text from memory. Recalling it sticks far better than rereading.
Output
You put it to use: you talk with your tutor whenever you like and practice in the Gym.
Spaced repetition
The words you save come back in your texts just before you forget them, with no loose flashcards.
The error cycle
Each mistake is grouped under the rule that explains it and comes back in your next texts until you master it.
Your mistakes write your next text
Glosae doesn't log un as a one-off slip: it notes that you're getting noun gender wrong. When a rule keeps coming up, it becomes your weak spot, and your next text brings it back in new sentences, along with the words from your lexicon that are due for review. Get it right in three texts in a row and it's mastered.
A fixed course is the same for everyone. In Glosae, every text is new and built from what you find hard.
More ways to practice, one lexicon
Everything you tap is saved to your lexicon and comes back when it's due.

Library
Read articles and books (.epub), listen to podcasts, or watch YouTube videos with the Glosae browser extension, at your own pace, tapping any word.

Gym
When a pattern keeps tripping you up, you drill it with sentences from your own texts until it stops costing you effort.

Talk
Speak or write with your tutor whenever you like, not just while studying a text. It adapts to your level and goes over your mistakes.

Free writing
Write about anything you want. Before you see the correction, you try to spot the mistakes yourself.

Frequently asked questions
Is it free?
Yes. You can start for free, no card needed. The free plan has a daily usage limit. Basic and Premium give you more usage and more natural voices; Premium also adds live voice calls.
Can I start from zero?
Yes. If you don't know the language at all, you start with a few first steps and very simple A1 texts.
How does it work?
Each text is studied in three steps, at your own pace: first you understand it, with the sound and the translation of every sentence; then you write it from memory; finally, you see what tripped you up and save the words you missed. Your mistakes are grouped by rule and come back in your next texts until you stop making them.
What is Glosae's method based on?
On five pillars of the science of learning: comprehensible input (texts at your level), active recall (you write them from memory), output (you talk with your tutor), spaced repetition (your words come back before you forget them) and the error cycle: your mistakes are grouped by rule and come back in your next texts until you stop making them.
Can I practice speaking?
Yes, by voice or in writing, whenever you like, not just while studying a text. Your tutor adapts to your level and goes over your mistakes.
Which languages can I learn?
Spanish, Italian, Portuguese, German, French, Chinese, Japanese, Russian, Turkish, Norwegian, Greek, Romanian, Polish and Swedish, from English, Spanish, Italian, Portuguese, German or French.

Do I need to install anything?
