Symbiose
What Symbiose Chat does
One-to-one messaging
Talk with a partner, friend, relative or colleague. Reply in your own language, the language you are learning, or a mix of both.
On-device translation
Translate sentences and words in eight supported languages on native iOS and Android builds after downloading the language models. The original message stays in place alongside the meaning.
Word explanations
Explore a word or phrase from the conversation. Learn what it means in the sentence where you encountered it.
Writing help
Start with what you want to say and ask for help expressing it in the other language. Review a suggestion before choosing what to send.
Corrections
Use corrections to work on your own messages.
Saved vocabulary
Save words from your chats with the sentence they came from. Return to vocabulary that already means something to you.

What makes Symbiose Chat different
Start with someone you know
Symbiose is built around existing relationships. Invite your person into a conversation rather than browsing public profiles.
Use your actual conversations
Your messages supply the words and sentences to learn. A plan for the weekend or a question about dinner gives you something specific to understand and answer.
Let each person learn at their own pace
One person can keep chatting naturally while the other uses translation and writing help. Both people can also learn each other's language.
Keep the conversation going for free
Human messaging stays available when the free AI learning allowance runs out. You can keep talking and return to additional help when your allowance renews.
Who Symbiose Chat is for
- Partners who want to use more of each other's language.
- Relatives reconnecting through a family language.
- Friends living in different language environments.
- Roommates and colleagues who already talk regularly.
- Two people learning each other's languages at different levels.
Why Symbiose Chat is being built
Being told to talk with someone fluent sounds simple until you cannot follow their reply. The conversation often switches back to a shared language, or the stronger speaker has to translate every sentence.
Symbiose is built to make that conversation possible earlier. Your person can write naturally, and you can get enough help to understand and answer before you are comfortable doing everything in the new language.

How Symbiose Chat works
- Choose your languages. Set the language you speak and the one you want to learn.
- Connect with your person. Share an invitation or connect with someone you already know.
- Start talking. Read and reply in whichever language lets you say what you mean.
- Ask for help when you need it. Translate a message, explore a word, work on a reply or save an expression.
Translation runs on the phone in native iOS and Android builds once the required language models are downloaded. Writing help, explanations and corrections use remote processing. Read how Symbiose handles your data.
