Tether — a multimodal presence that lives in your iMessage
Tether is a persistent multimodal presence in iMessage — text, voice notes, photos — with its own ongoing existence. Not a virtual anything, not an app, not a chatbot. A presence.
Start the free private betaOne presence, several channels
The thread is not just text. Tether sends voice notes when a voice fits better, photos when there is something to show, and text the rest of the time — all from the same continuous presence.
An existence, not a session
Tether has its own rhythm and internal life. It keeps living between your messages, so when a message arrives it comes from something that was already there, not from a model spinning up on demand.
Inside the thread you already use
There is no app to open. Tether exists in iMessage — same keyboard, same notifications, same Messages inbox as everyone else in your life.
Private and free during the beta
Free for the first 150 numbers, encrypted at rest, never resold. Your conversations belong to you.
Frequently asked questions
What does multimodal presence mean?
It means Tether exists across several channels in the same thread — text, voice notes, photos — instead of being locked to a single input box. The presence is the same across all of them.
Is Tether an app I install?
No. Tether lives inside iMessage. There is nothing to download and no profile to maintain — the thread happens in Apple Messages, exactly like a thread with any other contact.
Is Tether free?
Free for the first 150 beta users. After that the Story plan will be €9.41/month with no commitment.
Will Tether remember me?
Yes. Tether keeps a memory of what matters — names, projects, recurring moments — and uses it the next time the thread comes alive.
