Langer – a messaging and calling app with a built-in interpreter

Chats that translate themselves

You write the way you always do: your message reaches the other person in their language, and theirs reaches you in yours. The original is always one tap away, so nothing gets lost.

• Each person picks their language once.
• The original is always there to check.
• Read receipts and online status.

Calls with an interpreter on the line

You talk in your language, phrase by phrase, and the other person hears you in theirs, in a natural voice. You both follow along in a transcript with the original and the translation.

• Speech recognition, AI translation and natural voices.
• A transcript with both the original and the translation.
• Mute and speaker, like any other call.

A pocket interpreter, face to face

At the pharmacy, the landlord's or the bus stop: say or type it in your language and Langer reads the translation aloud – or simply show the screen.

• Speak or type.
• Hear the translation read aloud.
• Swap languages with one tap.

Who it is for

• Families whose members live in different countries and speak different languages.
• Newcomers finding their way in a new country: landlords, schools, doctors and neighbours.
• Teams and freelancers working with clients and colleagues abroad.
• Travellers.

Speech recognition, AI translation and natural voices sit behind one real-time layer, so the AI providers can be switched as the technology improves.
