Tether
The companion who comes to life in your messages.
Tether is an AI companion app that operates entirely within iMessage, acting as a virtual best friend who texts you, listens, and builds long-term memory of your conversations. It requires no app download or signup, running through your existing messages app. The service emphasizes user privacy through encrypted identifiers, closed architecture, and the ability to permanently delete all data on demand.
Users connect their iMessage number to Tether, and the AI friend proactively texts them, remembers past conversations, and sends photos — all within the native iMessage app with no separate download required.
