explain itself
One scan. Your tutor explains the grammar, builds your vocabulary, and tests you - all from the page you just photographed.
Three steps to learn a language from your own textbook.
Photograph the page
Snap any page from your textbook or workbook. Decent light is all it needs.
Read it explained to you
Grammar and structure explained in plain language - like a private tutor.
Speak New Language
Vocabulary sticks, grammar clicks. A new language lives in you now - go flex it.
Learning velocity
Learn 4 times faster than traditional self-study.
Your only job is to learn.
Einlang handles every step between your textbook and actually studying - vocabulary, exercises, grammar notes, all of it, instantly.
Preparation
Your materials, ready before you sit down.
Source Material
Built from your textbook pages.
Availability
Einlang is always available, in contrast to your teacher.
Vocabulary, grammar, and tricky combinations - from your book.
Teaches every word before you hit the first exercise.
Einlang reads your page and works through each new word first - so when an exercise appears, nothing on the page is unfamiliar.
Explains the rule before you apply it.
The rule comes before the exercise. Einlang walks through it the way your chapter teaches it - so you practise with understanding, not guesswork.
Your book's exercises, enlarged inside the app.
Einlang copies the exercises from your physical page so you complete the real material - no substitutes, no rewrites.
Corrects your mistakes with an explanation, not just a mark.
Get an answer wrong and Einlang shows you the rule behind the mistake - grounded in your chapter - so you understand what went wrong, not just that it did.
Answers any question about your exact chapter.
Stuck mid-exercise? Ask anything. Einlang answers from your page - not the whole language - so the explanation always connects to what you are studying right now.
Shows every word in the sentence it came from.
Vocabulary isn't taught in isolation. Each word comes with the sentence from your page - so you learn meaning and usage together, not just translation.

I used to leave lessons feeling dumb
Now I show up knowing more than I thought I did. That feeling changed everything about how I see myself as a learner.

Three years of shelf guilt - gone
Scanned it on a Sunday afternoon. By Monday I'd done more than in those entire three years combined.
jamesbcn
Something switched in my classroom
My students stopped glazing over mid-lesson. When practice comes from their actual book, they arrive caring. I didn't expect that.
ms_sophie_r
I quit every app I've ever downloaded
Not this one.
justdano
First time I understood before class
Not during. Not after looking it up. Before.
lenakay
My daughter asks me to sit with her now
She used to put her headphones in and disappear into homework. Last week she pulled up a chair for me. I don't know what changed but I'm not questioning it.
carlitos_m
B2. Seven months.
I cried when I saw the result.
anna_t
I sat in a room full of Germans and didn't panic
That feeling. That's the one I was chasing.
tomgermany
My tutor never once explained the why
Two years memorising rules I didn't understand. The first time Einlang explained why a case changes, I actually felt angry at how simple it was. Then relieved.
mariamoves
Two weeks. Then three. Then four.
That's never happened with a language app before.
raj_es
Grew up speaking it. Never writing it.
Now both.
elenita_v
I look forward to my commute now
That's a strange thing to admit. But I genuinely do.
