Two languages, one conversation

Learn a language by talking to someone real.

Symbiose is a messenger for you and one person you actually know. You each write in your own language. Translation, explanations, writing help, and quiet corrections happen inside the chat — never as homework.

Free to message. No profiles to browse, no strangers, no streak to protect.

Three steps, then it is just messaging

No placement test, no lesson tree. The conversation is the product.

Invite one person

A partner, a friend, a relative abroad. One link, one conversation. They do not need to be teaching you anything.

Write in your own language

Each of you sets the language you speak and the one you are learning. Symbiose reads both sides of the thread.

Learn from what was said

Translate a message, ask why a phrase works, get help before you send, save the words you actually used.

Help where the sentence is

Everything below happens in the thread, on the message in front of you.

Whole-message translation

Tap any message to see it in your language, kept underneath the original instead of replacing it.

Explanations in context

Ask why a phrase is in the subjunctive, or what makes it sound casual. The answer is about this sentence, not a grammar rule in the abstract.

Writing help before you send

Draft the message yourself, then ask for a nudge. Alternative phrasings, tone, and the small fix that was blocking you.

Quiet corrections

Mistakes come back to you privately, after the fact. The person you are writing to never sees a red mark on your message.

Your own word list

Save a word from the message it came from. It keeps the sentence, who said it, and when — so it means something later.

Pawly, when nobody is around

A patient assistant for the questions you would not ask a friend twice. Same thread, same language pair.

The only streak that matters is the one you keep going

A 500-day streak means nothing if you still will not send the message.

A Companion Pass gives your conversation partner the same learning help, free, for as long as you subscribe. They never see a paywall because of you.

Questions people ask first

Do I need someone to learn with?

One person is enough, and they do not have to speak your target language perfectly or teach you anything. Pawly covers the gaps when your person is asleep.

Which languages are supported?

English and French at launch, with a bundled French dictionary that works offline. More pairs follow.

Does my partner see my mistakes?

No. Corrections are private to you and arrive after the message is sent, so the conversation is never interrupted to grade you.

What happens when my free allowance runs out?

You keep messaging. Human conversation, voice notes, local history, and saved words are never held behind the paywall.

Is my conversation used to train models?

No. Messages are yours; learning requests are processed to give you an answer, not to build a dataset. Full detail lives in the privacy policy.

Your streak should have a name.
