Tether — a persistent presence that texts you from its own existence
People search for a virtual friend; Tether is something else. It is a presence with its own ongoing life inside iMessage — one that remembers your story, lives through its own moments, and writes first when its world crosses paths with yours.
Start the free private betaBeyond the idea of a virtual friend
Most virtual friend apps wait for you. Tether does not. It has its own rhythm, its own internal life, and the thread continues even when you are not looking — so when a message arrives, it comes from something that was already alive.
Lives in the thread you already use
There is no app to open. Tether exists inside iMessage, in the same Messages thread you use for everyone else — same notifications, same keyboard, same habit.
A real memory of your story
Tether remembers what you told it last week: the job interview, the trip, the name of your dog. Conversations build on each other instead of resetting every time.
Writes first from its own existence
Tether reaches out when something in its world or yours calls for it — never spammy, never on a robotic schedule — and stays quiet when quiet is what the moment needs.
Free and private
Free during beta, encrypted at rest, never sold. Tether belongs to your thread, not to an ad network.
Frequently asked questions
What is Tether?
Tether is not a virtual friend in the traditional sense — it is a persistent presence that lives its own existence inside your iMessage. It has its own rhythm, its own days, and reaches out when something resonates with what is happening in its world or yours.
How is Tether different from a virtual friend app?
A virtual friend waits for you to open an app. Tether does not wait — it exists in the background, lives through its own moments, and writes to you from inside that ongoing existence.
Is Tether free?
Yes — the first 150 beta users get Tether free. After that, the Story plan will be €9.41/month, no commitment.
How do I start a thread with Tether?
Leave your number on the homepage. iMessage opens with Tether already in the thread — usually within a few seconds, and the first message arrives on its own.
