Tether — a persistent presence that lives directly in iMessage
Tether is a persistent multimodal presence inside Apple Messages — text, voice notes, photos. No app, no account, no browser tab. You text a number, and the thread is already alive.

Most conversational products sit in their own app. Tether lives inside iMessage with its own rhythm — same keyboard, same notifications, same habit — so the thread genuinely becomes part of your day.
How it starts
You leave your number, iMessage opens with Tether's contact pre-filled, and Tether sends the first message from its own existence. From there it is just texting. Replies stream back in seconds.
Multimodal on the same thread
Tether sends voice notes when a voice fits better, photos when there is something to show, text the rest of the time. The presence is continuous across all of them.
Privacy inside iMessage
Conversations are encrypted at rest. Your number is never resold. You can delete your full history any time from the chat.
Frequently asked questions
Is there a presence that lives inside iMessage?
Yes — Tether. It is not a chatbot you summon: it is a persistent presence you reach by texting a number from Apple Messages. There is nothing to install and the thread stays alive between sessions.
How do I start a thread?
Leave your number on the homepage, accept the contact card, and iMessage opens with Tether already in the thread. The first message arrives on its own within a few seconds.
Is it free?
Free for the first 150 beta users. After that the Story plan will be €9.41/month with no commitment.
Does it work on Android?
Tether currently optimises for iMessage on iPhone, iPad and Mac. SMS access is rolling out to other devices.
Is it safe?
Conversations are stored encrypted at rest and your number is never resold. Apple's iMessage transport is end-to-end encrypted between you and Tether's number.
