One device, two languages: a face-to-face conversation with Miteinander
Your bicycle tyre keeps losing air. At the repair shop, you want to explain the problem, ask about the price and find out when you can collect it. You are standing in front of each other, but you do not share a language. Miteinander is built for situations like this: two people having a conversation on one shared device, using speech or typed text.
The key is a deliberate sequence: speak, review the recognised text, send, and translate with the conversation in context. Here is how to get started.
Give the conversation a starting point
Open the Miteinander web app and choose your language. Miteinander offers 21 languages, including English, German, Turkish, Ukrainian and Arabic. The interface is available in these languages too.
When you start a conversation, you can first describe the situation by typing or speaking. Then choose the other person’s language. For our fictional bicycle-shop example, the context might be:
I am at a bicycle repair shop. My rear tyre is losing air. I want to know what the repair will cost and when I can collect the bike.
This gives the AI a frame for the topic and relevant terms. A short description of where you are, what you need and what you want to find out is enough to begin. Adding context is optional.
Check your own words before translating
Type a message or record it. With voice input, speech is first converted into text. That text stays in the input field as an editable draft. Translation only starts when you send it.
Take a moment to read the draft. Has it captured the right part of the bike? Are numbers and your question correct? If “front tyre” appears where you said “rear tyre”, change it before sending. You can also add a detail:
My rear tyre has been losing air since yesterday. Can you repair it today?
You decide what you want to say: phrase your message in your own language, adjust it as needed and send it for translation when you are ready.
Take turns on the same device
Once sent, the original and translation appear in the conversation history. After a successful translation, input switches to the other person, with input labels in their language. You do not need a second device or a shared messenger account.
Further translations take the completed conversation history into account. A follow-up such as “And when would it be ready?” can therefore be considered as part of a discussion about a repair, rather than as an isolated sentence.
You can also make follow-ups more specific: “When would the rear tyre repair be finished?” keeps the subject clear for both people.
A practical routine for everyday conversations
The same approach works as a starting point at accommodation, with neighbours or when asking about a service:
- Keep one main point per message. Describe the problem before asking about price or timing.
- Check names and numbers. Pay particular attention to times, amounts and addresses in your source text.
- Make follow-ups specific. Name the item instead of relying on “that” or “it”.
- Type when it is noisy. You can use text without a microphone, or edit recognised speech afterwards.
- Confirm important arrangements. State the price and collection time again and check them together.
Trial credit and your own API key
New users may receive a one-off, limited allocation of free starting credit to try Miteinander without their own API key. You can see your available starting credit in the app.
To use your own OpenRouter API key, enter it in expert mode. You can use the same key in both key fields. You pay only for AI usage through your OpenRouter account; using Miteinander in this mode is free. There are no additional app fees, and your app credit stays untouched.
What stays in your browser – and what is processed elsewhere?
Your conversation history is stored locally in the browser on your device. Miteinander does not keep a permanent copy of your conversations on its own server.
For speech recognition and translation, the required audio or text and conversation context pass through the Miteinander server to OpenRouter and the relevant AI provider. The app server handles these contents only for the request and does not store them permanently. The connected services perform the AI processing; the saved conversation history stays in your browser.
You can return to the originals and translations there later. Clearing your browser data also removes these locally saved conversations.
Your access, across several devices
Your personal access code lets you use the same access and app credit on several devices or in different browsers. You can open Miteinander on your phone while out and about, or on your tablet at home.
Conversations stay in their respective browsers. The code restores access to your credit rather than synchronising conversation histories. If you use your own OpenRouter keys, set them up separately on each additional device. Keep your personal access code safe.
Keep the conversation in your hands
Miteinander brings you into conversation on one shared device: speak or type in your own language, adjust your message and have it translated in the context of your exchange. That leaves more room for what you actually want to say.
Start with a small everyday question. Open Miteinander, choose your two languages and briefly describe the situation. You can find further reading in the Miteinander section.
