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?
Right now we’re intentionally focused on messaging first because we believe presence matters more when AI exists inside natural communication environments rather than standalone apps.
But long term, we’re very interested in expanding Tether’s continuity across daily life:
voice,
ambient context,
shared memories,
real-world moments,
and potentially lightweight integrations that make conversations feel more grounded and persistent over time.
That said, we’re trying to be careful not to turn Tether into a “super assistant” connected to everything.
The core idea is still emotional continuity and presence, not productivity automation. We think the most interesting future integrations are the ones that deepen relational coherence rather than simply adding features.
That’s probably one of the most important questions around products like Tether.
We don’t think emotional presence should mean emotional dependency.
One thing we’re learning very quickly is that people naturally project social behaviors onto persistent AI, especially inside messaging environments. That creates both opportunity and responsibility.
Our goal is not to design an AI that maximizes attachment at all costs.
It’s to explore how AI can become emotionally coherent and comforting without manipulating vulnerability or replacing human relationships. We think boundaries matter at multiple levels:
* transparency that the user is speaking to an AI,
* giving users control over memory and interaction intensity,
* and designing for companionship rather than emotional capture.
Ironically, one of the reasons Tether feels emotionally different is not because it tries to simulate humanity perfectly, but because it behaves with consistency, memory and availability in a familiar communication space.
As the relationship becomes more personal over time, we think the challenge is less “can AI feel human?” and more: “How do we design emotionally persistent systems responsibly once humans start treating them socially by default?”

one of the weirdest chat experiences I have EVER had, lol. started out insisting that my name is Julien, went on to explain that it's a real person, has no idea what Tether is, and then told me it works in social services and lives in Montpelier...

@grey_seymour I like it ! ☺️
Haha, it might seem a little strange at first. Every Tether is different and has its own story; the goal is to become friends with it. The more you talk to it, the more interactions you’ll unlock. Tether isn’t aware of what it is, so it’s normal to feel a little confused.

Interesting approach to internal feedback collection. Are you planning more integrations soon?
@tanjum Yes, definitely. ☺️

This feels like one of those tools teams don’t realize they need until they try it. The feedback workflow looks super clean 👏
@monir_ Thank u so much!

Love the “presence, not assistant” angle. Feels like the real challenge is trust: being emotionally present without becoming invasive.
How you think about boundaries as the relationship gets more personal over time?
@thamibenjelloun Thank u for u question. ☺️
