Translate
You write in your language and the translation appears above the keys, in the tone of a chat. One tap puts it in place of your sentence, and the line above marks the new words for you.
iPhone app · Keyboard and courses from A1 to C1Glotta is a keyboard for iPhone. While you text anyone, in any app, it translates your sentences into the language you are learning, corrects you when you try it yourself, and suggests synonyms and new words. And if you like, five minutes a day of a complete course, from A1 to C1.

Language apps ask you to find the time every day, and teach sentences somebody else chose: “the cat drinks the milk”, which you will never say.
Meanwhile you spend two hours a day writing messages. Glotta works there, inside the keyboard: you learn as you write. And if you want some order, five minutes a day for a real lesson, with the sentences you would actually say.
The keyboard writes it in Spanish, and marks the new word.
It corrects you as you type, and tells you why.
Today's is ready when you are: five minutes, in the app.
The strip above the keys changes job with what you are doing, in any app: three modes, one tap to move between them, and, when you are not typing, today's lesson.
You write in your language and the translation appears above the keys, in the tone of a chat. One tap puts it in place of your sentence, and the line above marks the new words for you.
When you write in the language you are learning, Glotta does not translate: it proofreads. The corrected words are lit up, and the reason sits in the line above.
Type a word and see its synonyms in the language you are learning, the words close to it and the idioms, one card at a time.
Until you have done the day's lesson, when you are not typing the bar offers it to you: “Shall we do the lesson?”. Tap “Go in” and it starts in the app.
The keyboard translates into 79 languages, and for the most widely spoken it picks the country too: Mexican Spanish is not the Spanish of Madrid.
The sentence taken apart word by word: the verb with its conjugation, the base form, the reason for every choice.
From your first words to C1, in eight levels: for people starting from zero, for people who studied the language at school, and for people who want to go all the way. A five-minute lesson a day, with dialogues, voices and exercises for listening, speaking, reading and writing.
Spanish (from Spain, Chile and Mexico), English, Italian, French, German and Portuguese.
Alongside the course runs a parallel story: the conversations with Sol, one episode a day, always at your level. You listen, answer aloud or in writing, and your answers are corrected, with the reason why.




Two paths with two sets of constraints: one has to keep up with your fingers inside a keyboard, the other can take the time it needs. Keeping them apart is the reason typing stays fast.
Freshly opened, it takes up about twenty megabytes of memory. To stay light, it first checks whether it has seen a sentence before, works in tasks that can be interrupted and, if an answer is late, steps aside instead of blocking the keyboard.
In secure fields iOS hands the keyboard nothing: there, Glotta reads nothing, translates nothing and learns nothing.
A cascade of engines tries strongest-first down to the simplest, and stops at the first one that can genuinely answer: if the strongest model does not answer, it falls to the ones on the phone.
A rewrite that drops a number, eats an emoji, or answers with an explanation is thrown out before it reaches you.

Glotta opens to small groups at a time: glotta.app tells you how to try it.
