iPhone
Photograph what you cannot read. 39 languages, explained in yours.
Rosetta turns writing you cannot read into a lesson you can revisit.
Photograph a sign, a menu, a label — even when you have no idea what language it is. Rosetta identifies it, translates the sentence, breaks it into words with readings and parts of speech, explains the grammar, and reads every word aloud.
39 LANGUAGES, IN ANY DIRECTION
Rosetta teaches every language your iPhone can speak aloud — 39 of them, from Japanese and Korean to Thai, Arabic, Greek and Cantonese. Any of them can be explained in any other, so you learn Thai through Japanese, or Greek through Spanish, whichever you actually think in.
A LESSON, NOT A TRANSLATION
Every reading gives you the sentence, its meaning, each word with its pronunciation and role, the grammar worth knowing, and example sentences you can reuse. Scribble over part of a crowded page to focus on just that phrase.
WORDS THAT STAY
Save words into a wordbook for each language, add your own notes, and review them on a spaced schedule that brings each word back just before you would forget it.
FREE AND PAID
Rosetta includes 3 free AI readings. Wordbooks, notes, pronunciation and history are free forever — only AI readings are counted. Rosetta Pro removes the limit.
