For language learners
See how a language thinks, in colour.
Most translation apps hand you a sentence and leave you to trust it. Janau gives every matching pair of words the same colour on both lines, so you can see which word became which, notice where the order changes, and start to understand why.
English
The old man watched the harbour lights fade.
Spanish
El anciano miraba apagarse las luces del puerto.
Point at any phrase to light up its partner. Notice *fade* and *apagarse* swap places — the colour is how you spot it. Tap a phrase to learn why.
How it works
Every word, matched and coloured.
Janau translates, then does the part other apps skip: it works out which words in your sentence became which words in the translation, and gives each pair a colour you can follow with your eye, so the answer also shows its working.
Type it, say it, or point your camera
Type, paste, dictate, or point the camera at a menu or a sign. It all lands in the same place, and the water ripples while Janau thinks, so the wait feels alive rather than stuck.
Each pair gets its own colour
Colours follow your sentence in reading order and repeat on the translation, so one colour means one thing on both lines. When the two languages order their words differently, you see it at once.
Tap a word to learn why
Tap any pair and Janau explains it: what it means literally, how formal it is, and the other words it could have chosen. Press and hold to lift a pair out on its own.
The water
The loading screen is water you can push.
Not a decoration — a real wave simulation, the same code the app runs. Drag a finger and the water piles up beside it; let go and the piles roll away as waves, hit the edges, and come back.
In the interest of honesty: this does nothing
The water translates nothing, measures nothing, and tells you nothing about your sentence. It is a wave simulation built for a loading screen, kept because a thing you see a dozen times a day may as well be worth looking at — and because it was fun to make. That is the whole justification, and we are at peace with it.
The colours
Six colours, chosen for every kind of eye.
When colour does the work, it has to work for everyone — including the one in twelve men who see two hues as one. Janau’s six colours are spaced so that no two neighbours blur together under the common kinds of colour blindness, and each is also a different brightness, so the pairs stay distinct even in black and white.
Colour is not the only clue
Pairs stay apart for the common kinds of colour blindness, and tapping any word names its partner in plain text — so you are never guessing from colour alone.
More than six pairs? The colours repeat
Rather than squeeze in a seventh colour that would crowd the others, long sentences start the set again — and Janau checks that a repeated colour never lands next to its twin.
The app
Three screens do the whole job.
