Family
A grandfather in Lithuania wants to talk with his grandson in the United States. The grandfather speaks Russian and Lithuanian; the grandson grew up with English. Skype and FaceTime connect them — neither can make them understand each other.
Public beta · open to everyone
Speak your language. Be heard in theirs.
Langer is a messenger with a built-in interpreter. Chats and calls translate themselves as you talk, so families, couples and teams can finally speak freely — each in their own language.
On iPhone through Apple’s TestFlight app, on Android from Google Play.

Why Langer
Video calls connect people. They don’t help them understand each other.
Work
A software developer in Lithuania works with clients from Lithuania and Spain. Every message goes through copy-paste: into a translator, back into the messenger, and again for every reply.
Real situations from Lithuania.
Langer puts the interpreter inside the conversation.Working today in the beta
One app for every conversation
Everything in this section already works in the beta. The screens are illustrations.
Working prototype
Chats that translate themselves
Write the way you always do. Your message arrives in their language, theirs arrives in yours, and the original stays 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

Group chats with an AI assistant
A client writes in Lithuanian, the developers read in Ukrainian and Russian, the manager in English — and an assistant turns requests into tasks. The same works for a family chat across three countries.

Why this translation
Idiom. Literally “my hands don’t reach”. It means: I haven’t found the time yet.
Tone: casualConcept

Formal or friendly? An idiom? Langer points out the nuance and helps you answer in the right tone.

Help us take down the language barrier
We are opening an angel round for business angels who want to take Langer from a working prototype to a public launch.
The problem
Millions of people in Europe live, love and work across a language barrier: families split between countries, newcomers, cross-border teams. Video calls connect them but don’t translate; translator apps handle phrases, not conversations. So people copy-paste, wait for someone to translate, or stay silent.
Why now
Speech recognition, AI translation and natural-sounding voices have crossed the quality line for everyday conversation, and their cost keeps falling. What used to be a research demo can now live inside a messenger.
What exists
A working prototype with translated chats, translated voice calls and a voice translator in 74 languages, on a real-time backend that can switch AI providers. A web app is in development.
Vision
A messenger where language simply stops mattering — first for families and newcomers in the Baltics, then across Europe and for the organisations that serve them.
Business model
Hypotheses we will test in the beta- Freemium: a free plan with a weekly limit, paid plans, and credits for more
- A family plan for mixed-language households
- Seats and an API for clinics, schools, municipalities and support desks
The round
An angel round, open now. It funds the public launch on iPhone, Android and the web, voice quality, more languages and the first pilots with organisations.

FAQ
Questions, answered
How do I join the beta?
It’s open to everyone: install Langer on your iPhone through TestFlight or on your Android phone from Google Play, with the links at the top of this page.
Which languages are supported?
Our main languages are English, French, German, Italian, Lithuanian, Polish, Portuguese (Brazil and Portugal), Russian, Spanish and Ukrainian, and 64 more are translated too, from Arabic and Chinese to Turkish and Vietnamese: 74 in all, each into every other. We will add more based on demand — tell us which ones you need when you sign up.
How good is the translation?
Modern AI translation is very good for everyday conversation, but it is not perfect. That is why Langer always keeps the original one tap away. For legal or medical decisions, please use a certified interpreter.
How is Langer different from a translator app?
Translator apps are great for one-off phrases. Langer is where the conversation itself happens: your contacts, chats and calls, translated both ways automatically, with the original always there. No more copy-pasting between a translator and your messenger.
Which devices does it work on?
iPhone and Android, and in your browser.
Does it cost anything?
You can use Langer for free, within a weekly limit — about 20 minutes of calls a week, and plenty for everyday chats. Paid monthly plans raise the limit, and credits, bought separately, keep you going when you reach it. A call uses the limit of whoever makes it: calls you receive are free.
