Translate
A translation you can take apart.
Paste a menu, a message, a paragraph you got stuck on. Set the region, the style and the tone, then take the answer apart to see how it was built. On every paid plan.

A translation box answers. This one explains.
Every general-purpose translator hands you a block of text and stops. That is fine when you only wanted the meaning. It is useless when the point was to learn something from it.
What you usually get
One block of text, in one register, for whichever region the model settled on. No way to ask which word did what, why an idiom came out the way it did, or how sure the answer was in the first place. When it looks wrong, your only move is to try again and hope.
What you get here
The same translation, with the reasoning underneath it. Hover a line to see the sentence it came from. Click it for a grammar walkthrough. Open the breakdown for the unit-by-unit reading, the idioms, and how confident the answer is.
Before you translate
Three dials, because "Spanish" is not a specification.
The same sentence comes out differently in Mexico and in Spain, and differently again in a work email and a text to a friend. Say which you want before you press Translate.
Region
Pick the region you actually want, so the vocabulary and the pronouns match where the words are going instead of averaging across a continent.
Spanish comes with Latin America, Spain, Mexico, Argentina and Colombia. French with France, Quebec, Belgium and Switzerland. Portuguese with Brazil and Portugal.
Style
How close the wording stays to the original. Faithful tracks the source, Simple flattens it into plain phrasing you can follow, Advanced reaches for the more sophisticated construction.
Faithful, Simple, Advanced.
Tone
Register, set on purpose rather than guessed at. Business for the work email, child-friendly for something you are reading to someone, poetic when the source is.
Default, Formal, Casual, Academic, Business, Child-friendly, Story, Poetic, Conversational.
Region appears for the languages with regional variants worth separating. Tone appears for the languages with a real formal and informal address, because everywhere else it would be a control with nothing to control. Style is on every pair.
After you translate
Take the answer apart.
Five ways into the result you just got back. This is the one place in Lexxio with all of them, so when a sentence in a book will not come apart, paste it in here.
Hover for the original
Translating into the language you are learning, the result is matched to what you typed sentence by sentence. Hover any line to see the sentence it came from.
Show breakdown
The translation split into units, each tagged with its grammar, so you can see which piece of the output came from which piece of the input.
Idioms, both readings
When a phrase does not go word for word, the breakdown gives you the literal reading, the actual meaning, and a short note on why the two are not the same.
How sure it is
Every translation carries a rating of High, Medium or Low. Worth having before you send the email, and worth having when the source was ambiguous to begin with.
Explain grammar
Click a sentence for a walkthrough of how the two versions line up, piece by piece. Built for the cases where the word order moves and there is no straight correspondence to point at. Going the other way, one button explains the whole passage.
Chinese, Korean, Japanese
Built for scripts you cannot sound out yet.
Pinyin, romaja or furigana over the result, a pinyin keyboard for typing Chinese, and a dictionary one double-click away.
Pinyin, romaja, furigana
Mandarin, Korean and Japanese results carry their readings above the characters, or swap the characters out for the readings entirely. One toggle, and you turn it down as you stop needing it.
Type pinyin, get hanzi
A built-in pinyin input for the Mandarin side, so you can type a Chinese sentence into the box without switching your keyboard over.
Double-click any word
Translating into the language you are learning, double-click a word in the result for its dictionary entry, without leaving the screen.
Hear it
Play the translation in the voice you choose, at the speed you choose, with the same voices Lexxio uses to read books aloud.
It keeps what you translated
Recent translations are saved, searchable, and removable one at a time. How many it holds on to is yours to set.
The honest part
This one spends your allowance every time.
Translate draws on your monthly translation, sized by how much text you send. Book pages and dictionary lookups are cached, so re-reading a page or re-checking a word costs you nothing the second time. Translate is not cached. Translating the same text twice costs you twice, so keep a copy of anything you will want again.
Up to 1,500 characters at a time. Paid plans only: included from the Reader plan up, on the desktop app and on your phone. Not part of the free tier.
Reading a whole book? That happens in your library.
Translate is for text that did not come from a book: a menu, a message, a paragraph someone sent you. Books go in your library, where the translation sits beside the page and the words you save turn into flashcards.
