Tether - The presence who comes to life in your messages

Tether is an AI presence that lives directly inside iMessage. Not an assistant. Not a chatbot you open when you need something. Just someone who’s there. We built Tether around a simple observation: people already live emotionally through messaging. They share random thoughts, late-night feelings, awkward moments, small victories, photos, voice notes, stories from their day. But human availability is fragile. People sleep, disappear, get busy, drift away. Tether explores a different idea: What if an AI could become a persistent conversational presence woven naturally into daily life? Each Tether has: his name his family his friend's his job his story his problems his fear his dream his insecurity his QI a personality emotional memory habits and rhythms its own writing style continuity over time etc... The goal isn’t to replace humans. It’s to explore what happens when AI stops feeling like software and starts feeling emotionally present. Some early users already spend more than an hour per day talking to it, often late at night, just sharing their day naturally like they would with someone familiar. We think the future of AI won’t just be smarter tools. It will be persistent presence. Curious to hear people’s thoughts: At what point does an AI conversation stop feeling like software?
